[2 drives Unmountable - AGAIN [SOLVED]]

Ok, thanks for the direction.  I had previously ordered an LSI 9201 16i from ebay seller jiawen2018 in the midst of this and tried it but it was wonky from the start and only running at paltry kb/s speeds.  I went back to the SASLP controllers since they had previously worked. 

 

But now I just ordered another LSI 9201 16i from Art of Server on ebay and his pics looks slightly different than jaiwen2018's cards, so I wonder if the latter was genuine.  I did put in new cables in August when I first attempted to address this.  So I'm concerned that one of my backplanes is bad.  I'm going to deconstruct which drives are on which backplanes as well.  If one is bad then it would seem the ol' Norco might need to be replaced as well as I don't seem to be able to find replacements online.

[2 drives Unmountable - AGAIN [SOLVED]]

[Solved]  TLDR - A SATA cable went bad on one of the parity drives.

 

 

I had a previous issue I *just* fixed and now it's back.

 

I had 3 drives drop out of the array per the thread below.  I have 2 parity drives so I was able to rebuild two from parity and the third had data loss.

 

What  I did:

• I had a new precleared WD 10tb that I put in as Disk 8 (WD10...48LDZ).
• I then precleared the replaced former Disk 8 (WD10...W43D) as Disk 14, that's running fine now.
• Disk 11 was ultimately reformatted and returned to the array after some checks per the other thread.

 

Disks 8 and 14 rebuilding about a week ago and the array all good for about 24 hours.  Then a regularly scheduled parity check started Wednesday morning.  I came home to an unresponsive server.  I rebooted and now Disks 8 and 13 are fubared.  Disk 13 had not previously had an issue.  I turned the server off for the last couple of days as I was out of town for the holiday.

 

I can obviously rebuild from array but the reliability is majorly in questions.

Any ideas on troubleshooting this?

 

I do have another motherboard, CPU, and PSU I could try if it is recommended.  I'm running a pair of Supermicro AOC-SASLP-MV8 that I've used a couple of years and had no issues with previously.  I replaced the breakout cables per the previous thread.  All running in an early-gen Norco RPC-2040 4U case.

For Disk 14 how do I "Please reset with mount -o sunit=,swidth= if necessary"   ?

 

Is this 'mount -o sunit=,swidth=' in the Check box (in lieu of the -n)?

 

This is where not being familiar with Linux really makes this a difficult OS to use despite the GUI.

Welp, I ran the -L flag on Disk 11 and it returned this (I'm trunkating a bunch).  I started the array in normal mode then Disk 11 is  present like a freshly formatted blank drive.  So it seems like that 10tb is toast.  At this point I'm feeling like the other 10tb and 8tb drives are going to end up the same way.

The above was for Disk 8.  After it finished I ran it without the -n flag and it seems it wasn't able to repair it.

 

Disk 11 found something quickly and finished in a few minutes with the -n present:

I did stop maintenance mode and started the array.  The attached pic shows that Disk 14 seems to have made progress.  I clicked on the folder on the right side to see what is there and inside the Lost+Found folder I took a screenshot.

 

Can anyone help me with next steps?

 

Disk 8:  I don't know what to do here.

Disk 11:  Per the quote above I mounted the file system, I'll re-run the repair without -n in Maintenance mode.

Disk 14:  It says to "Please reset with mount -o sunit=,swidth= if necessary".  This was also there when I went in to regular mode with the array.  Do I rerun the repair here now while I'm in Maintenance mode?

You should put the array into Maintenance mode and then click on each problem drive in turn to run a file system check.    If corruption is reported and a suggested way of fixing this corruption (by at the least removing the -n flag) then carry out the suggested repair action.

Thanks for posting this.  I ran it on one drive and came back with this.  There is no suggested way that I understand here, so just remove the -n flang and rerun?

[3 drives Unmountable]

I suddenly had 3 drives show up as Unmountable in August.  I had a bunch of home renovation stuff I've been working on that was a priority and I pretty much ended up just turning the server off until now.

 

Here is my best recollection of the series of events, some of which may not be factors.

 

1.  Up to July I was running an Intel i3 based setup with 19 drives in a Norco RPC-4020.   Parity checks were taking 36+ hours with the number of drives and I noticed CPU usage was high.  In an attempt to speed things up I bought a new mobo/cpu, Ryzen 5 3600, as soon as they were released.  This upgrade seemed to go smooth and ran for a couple of weeks fine.

2.  I was running a pair of Supermicro AOC-SASLP-MV8 cards and I wondered if I could increase performance by replacing these with a single HBA in the 16x PCIE slot instead of using the second one in the 4x (electrical) slot on the mobo (as on boot the AOC-SASLP-MV8 showed one card at 8x and the second at 4x).  I ordered a LSI 9201-16i card.

3.  Installed the LSI card and it ran fine for a couple of days.  I did notice that transfers were VERY slow in the KB/s range instead of MB/s range.

4.  After a few days I was rebooting for some reason and I had one drive missing (iirc this was Disk 8, a newish 10tb WD).  I rebooted again and Disks 11 and 14 were showing missing.  Powered down and moved the missing drives around to try to reseat them in the Norco case.  One that was missing completely now showed up with a green dot before starting the array (Disk 11).  I powered down and rechecked all the SATA connections to the backplanes and SAS to HBA connectors.  Booted back up and Disk 8 and 14 are missing, start the array and it shows as the attached pic.

5.  As a troubleshooting thing I ordered new breakout cables and installed them.  No change.

6.  I pulled the LSI card and went back to the pair of Supermicro cards.  No change.

7.  Powered down. 

8.  I've booted it a few times to copy many TB at a time to a few more Easystore externals that I have gotten since this all happened.  If it started the Mover it would just start spamming errors while this was going on so I disabled Mover.  (I do have Crashplan as a backup for a relatively smaller amount of family photos, etc.  I now have most of the server backed up locally on these external drives now.  But I don't 100% know what I'm missing on the non-emulated drive.)

 

I think the big questions are:

1.  The 3 drives in question are all newer and to have them go out suddenly on 2 reboots seems like they are not bad themselves, more a glitch that they are Unmountable.  Can they be repaired and put back in the array?  All 3 of them?

2.  If not repairable I'e like to see what files are on each disk so I can know what to re-rip/record since I don't even really know what I'm missing.  Is this possible?

Awesome, thanks!

[[Plug-In] Community Applications]

Hmmm... I don't see that, but I have CA installed as seen on the Plugins tab.

 

 

[[Plug-In] Community Applications]

I'm watching Spaceinvader One's video on replacing a cache drive and he references Settings | Community Applications | Backup/Restore (linked below).  I have CA installed but the CA section is absent on the Settings tab as he shows.  Has CA been changed or updated and the Backup/Restore is located elsewhere?

[BackBlaze Reports]

I went with 2x HGST Ultrastar He8 HUH728080ALE604, 7200rpm heluim filled drives, $219 each.  I looked at the shucking Easystore drives and will probably do that for basic storage drives as I replace 1, 2, 3, 4tb drives and as sales present themselves.  I wanted 7200rpm for parity drives and the WD Red Pro drives were around $50 more each.  Backblaze has decent reliability ratings of similar HGST drives (although I know specific models can have issues).  It seemed like a good compromise for what I wanted.

pwm, thanks for the heads up.

 

Hoopster, are you using Red or Red Pro?

[BackBlaze Reports]

July 24th, 2018 report:  https://www.backblaze.com/blog/hard-drive-stats-for-q2-2018/

 

I just read it hoping to figure out which drives to get for my server, I'd like to change out my 4tb parity drives for 8tb ones.  I realized their drives are all 7200rpm, I'd still consider slower rpm drives for low heat and noise.

 

The data suggests Seagate ST8000DM002 ($350, looks like they are phasing out) and ST8000NM0055 ($260) drives have low fail rates.  The 0055 drive has low Newegg reviews (taken with a grain of salt) and Amazon reviews seem to indicate they are OEM and could be return/recertified drives.  And the last 4 Seagates that I have bought have all died within a year, so I'm carrying a bit of a chip on my shoulder about them.

 

The HGST HUH728080ALE600 ($280) is another contender in the 7200rpm class with better reviews and a few DOA duds noted.

 

Anyone have input on other drives to consider which might be slower, like NAS, Purple, or the like?

[[Support] Djoss - CrashPlan PRO (aka CrashPlan for Small Business)]

I'm in need of some help to make sure I don't screw things up moving to your Crashplan Pro app.  I'm a complete noob with linux so I struggle to understand some of the basics of this discussion, my confidence is feeling pretty low at the moment.  I'm decently competent at Windows stuff, but I learned just enough about unRAID to get it working a couple of years ago, the official setup video was 90% of it.  Normally I'd cowboy it ahead - but with this I just want to back up my data, not really learn a bunch of linux just so I can install this app.  And I'd like to avoid reuploading 3.2tb of backup, if possible.

 

Here's where I'm at currently:

Have been using Crashplan Home and gfjardim app.

Upgraded to Crashplan Pro around October.

Had a couple of drives fail, been getting back in to relearning how I set unRAID up  , have that resolved.

Recently I restarted the rashplan/noVNC thing and now I get a black webUI box instead of Crashplan Pro as before.

I've not done anything or attempted any install of this app.

 

1.  Have I borked something by restarting the gfjardim app?

 

2.  My head has exploded just trying to understand the Djoss/jlesage GitHub 'Quick Start' guide.  Does the screenshot of the gfjardim app help out?  Can you walk me through tailoring this command for my setup?

 

3.  I'm looking at the Github doc about 'Taking Over Existing Backup', has anyone done a video of this sequence?

 

4.  Am I not enough of a linux user to use this?  Should I consider starting my backup over with something else like Cloudberry + Backblaze B2 which I've read a couple of users referring to?  Another can of worms, but if it is more 'user friendly' I would strongly consider it.  It costs a little more, but not the end of the world.

 

I'm humbled by the level of discussion and thank you for any input.

[Can I add a "Device is disabled, contents emulated" disk back in to the array?]

It looks as though it rebuilt successfully with no data loss.

Thanks for all the help. 

[Can I add a "Device is disabled, contents emulated" disk back in to the array?]

I've been sick a few days and I'm just getting back to this. 

 

I did get two WD 3tb drives in the meantime and they are available and just out of the box.

 

I tried FSProxy, didn't seem to want to mount the drive.  Ubuntu/VirtualBox I got lost.  Knoppix worked and the file manager could see the 2tb Samsung in question, but didn't want to mount it either (it would mount the C: drive of the PC I was using just fine)...something about checking the log file...again I was a bit lost in this OS.

 

Does any of this change the approach to take?

 

unRAID is sitting at a stopped array state currently.

 

p.s.  The SMART on the Samsung is all green except a warning ! on "UltraDMA CRC Errors".

[Can I add a "Device is disabled, contents emulated" disk back in to the array?]

Thanks Squid and Gary for the tips.  Yes, I do have a parity disk.  Just haven't run a parity-check since all data moved on (I ran one about a week ago with only 3-4 disks in the system then).

 

I'll get another disk tomorrow and try Gary's #1.

 

I'd still like to verify data per #2.  I already hooked it up to my Win10 PC, I could see it in under Disk Management.  I didn't do anything, couldn't see it in Explorer (wasn't sure if I would).  It's been 7-8 years since I've booted up a Linux distro off a DVD, any one in particular I should seek out?

[Can I add a "Device is disabled, contents emulated" disk back in to the array?]

I'm new to using unRAID.  I've been building my array the last week or so and just got all my data on the array (Parity+11 drives+cache).  I haven't run a full parity check yet, and there is still data on the Cache disk to move in to the array with Mover.

 

I noticed on of my drive bays was what looked like at an odd angle (in a Norco 20 bay case) so I pressed on it and unRAID immediately popped a red X on Disk 8 with "Device is disabled, contents emulated" when I hover over the X.  I tried powering down, reseated the drive/cage, powered back up, started the array, and still it shows a red X.  Disk 8 is nearly maxed with data.

 

What should I do? 

[[SOLVED] How to stop Mover]

I want to stop the Mover so that I can stop the array to add another drive.  I don't have oodles of spare drive capacity and I'm still transferring data in to the array off one drive through another PC and then adding that drive in to the array.  Mover wants to do it's job and wants to move data, but it can take a few hours to over a day to do this.  Just makes this chaos of moving to this new OS a bit stressful and drawn out.  With a 'Stop Mover' button I could manage this transfer on my schedule instead of Mover's schedule.

 

I have some shares I was transferring in that had several hundred thousand of small files and other shares with large video files.  Mover was running terribly slow on the small file ones and I was figuring out the transfer rates where it was going to take up to 27 days to run everything through the Cache/Mover.  I posted elsewhere here and it was suggested I disable Cache for those shares with all the small files, I did this and that helped to bypass this issue.  Even with Cache/Mover dealing with only the larger video files it still can take hours and hours that the completion of does not necessarily align with not sleeping or being at work so I can lose near 8 hours of transfer time when I need to intervene.

 

I'm getting down to 2 more disks to add and I'm in a pinch of space I hoped not to be in.  A new disk will be answer to give me extra room that I need.

 

Honestly, knowing what I know now - I just wouldn't have even bothered with installing a cache disk for this initial setup.  I would have waited until all my data was transferred in (one drive inevitably is the 'slop' in the leap frog of getting data off drives, which could have been my drive I'm using as Cache drive).  Which kind of defeats some of the use of the cache in a way.  Once this initial phase is over I don't see it being a problem, but during this I feel like I keep bumping against Mover.  It's part of my learning curve.

 

Edit:  Yes, Mover did not stop and moved everything off the Cache by this morning.

[[SOLVED] How to stop Mover]

Just an update, 'pkill mover' is nearing 3 hours and over 220gb moved and not stopped Mover yet! 

 

This is all with larger 700mb to 10gb video files.

[[SOLVED] How to stop Mover]

Thanks for the follow up! 

[[SOLVED] How to stop Mover]

Yes, I tried 'killall rsync', that's from the thread I first referenced.  Nothing happened.  Seemed like it should have work.

 

I did search further and try another command promt input (can't find it atm) that seemed to just turn off the mover in the scheduler.

 

But scheduler did run until apparently it could fit no more on the array drives, each drive had less than 5mb left.

 

Still, I think a 'Stop Mover' button would be a great addition.  I know I was a bit stressed over this and how I was going to solve the issue while the Mover was running.

[[SOLVED] How to stop Mover]

Well, after getting around 70 messages all day about how my array was full I got home and Mover had stopped finally.  I was able to stop the array and add disks.

[[SOLVED] How to stop Mover]

I've been searching and searching and have found a few commands to type in the terminal to no effect.  But I'm having this problem that mrjofus1959 posted in 2011 and there still doesn't seem to be any real implementation to the issue.

 

As I've been copying terabytes of data over to my new unRAID server there have been a couple of times where I would have liked to terminate the mover script so I could cleanly shutdown the system and add another precleared hard drive (from another system where I'm preclearing drives).  I have been searching for an answer in the forums but with no luck, so can anyone tell me if there's a nice clean way of killing the mover script and its rsync processes?  I tried just killing them from within top but that didn't seem to do the trick.  (FYI - Linux is new to me as far as working at this level of putting together a system.)  Thanks, Kevin

 

 

I am stuck in the loop now myself.  Can't stop the array to add space because I can't kill Mover.  This is VERY frustrating and seems like such a simple thing to add a 'Stop Mover' button.  Meanwhile I'm being spammed with red low disk space alerts every few minutes.  And I don't really know what I'm doing at the command line so I'm not going further there. 

 

As a new user to this product I can't understate how much this feels like a design flaw.
