Need Help... Three drives out!

[RussellinSacto]

Hi Everyone,

 

I think it's literally been a couple years since I last posted...  Unraid has been so reliable.  Well...  Now I need help.

 

The other day, I went to do my parity scan... and noticed a red ball on "Disk 1" (SN ending in 5W1G).  Not a big deal, I had two drives already live on the system that had pretty much nothing on them (Disk 5 could easily hold everything that was on Disk 1).  So I opened up Putty (for speed) and used Midnight Commander to move files from Disk 1 to Disk 5.

 

It ran and ran...  More than 24 hours - I knew it would take a long time...  I wasn't worried about it.  (I knew I'd later need to figure out how to remove Disk 1 from the set and rebuild parity, once the data was moved).  I understand that Disk 1 had already failed and the "move" was from dataset/parity combination to Disk 5.

 

Anyway, today I came home from work - and heard that evil hard drive clicking noise continuously... and errors on the Midnight Commander screen.  So, I cracked the case, disconnected power and data to Disk 1 (not parity) and fired it up.

 

In my browser, I now have an ugly scene:  Disk 1 Not Installed (I think this is what is said before)...  and Parity Disk and Disk 2 are now Missing (see attachment).

 

I need advice on what to do to keep as much as possible of my data. 

 

As a possible aside, my last two drives are on a standalone SATA controller card - all the rest are on the motherboard.  Maybe the MB has died?

 

Thanks for your advice,

 

Russell

Check your cables, you probably just bumped them when disconnecting drive1.

[RussellinSacto]

Thanks Turl,

 

I'm pretty sure they're snug...  But I'll check again.

 

Any other ideas?

 

Thanks,

You should check if they are being seen at the BIOS level.  Until that happens it is very unlikely that unRAID will be able to see them.

Thanks for the help.

 

I took it all apart - all power and data cables to all the drives... and reconnected them to the seven presumed good drives.  I tried a few combinations...  The two drives that had appeared as Missing - I traded out new SATA cables and connected them to never-used ports on the SATA card (instead of motherboard).

 

When Unraid Boots, I get three messages that say:

 

sata7: link is slow to respond, please be patient (ready =-19)

sata7: COMRESET failed (errorno=-16)

 

And then this ugly one:

sata7: reset failed, giving up

 

When the web interface comes up, the results are a bit different (see attachment).

 

Syslog was too big to attach - posted here:  https://www.dropbox.com/s/guf7ptcycy0pr22/syslog-20150728-214241.txt?dl=0

 

Looking forward to more advice.  :-)

 

Thanks so much,

As itimpi suggested, can you see those disks in the BIOS?

[RussellinSacto]

Sorry trurl,

 

I had included that originally - and accidentally deleted it as I cleaned up my posting...  The answer:  I'm not sure.  :-)

 

In the BIOS, in the hardware area it shows:

Primary IDE Master - Hard Disk
Primary IDE Slave - Hard Disk
Secondary IDE Master - Not Detected
Secondary IDE Slave - Hard Disk
Third IDE Master - Hard Disk
Fourth IDE Master - Hard Disk

 

Five drives.

 

Then in the Boot Order area, it shows this:

1st Drive - USB
2nd Drive - SATA:PM-St31500341
3rd Drive - SATA:PS-ST3000DM00
4th Drive - SATA:SS-Hitachi HD
5th Drive - SATA:3M-ST3000DM00
6th Drive - SATA:4M-ST3000DM00
7th Drive - RAID:03:00-1 ST315

 

Two drives (parity and the one I believe is dead) are connected to a "Sabrent 4 Port SATA PCI Host Controller Care with Raid Function (SBT-SRD4)" (I have the box).  So, that shows five SATAs, plus the RAID - not sure if the RAID is showing one drive, or if it will always be by itself.

 

When it boots, it looks to me like the RAID controller finds one drive.

 

Thanks for your continued help,

If you zip your syslog it will fit. Text compresses very well. Yours was only 24K.

 

If you think disk1 is dead and it is on the same controller as parity, you might try disconnecting disk1 and see if it will see parity then. I have had connected dead drives keep my PC from booting before.

[RussellinSacto]

Numerous tries...  I can't get either parity or Disk1 to work...  I believe everything critical is backed up.  But if I can squuezevdata out of these drives, that might be beneficial.  Any ideas?

 

Thanks,

Boy, this is really kicking my a$$.

 

I bought a new hard disk to replace the bad parity drive.  I removed both the bad parity drive and the other drive that had problems.

 

I did an initconfig and got the array fired up... no problems.  It started to do a parity build, but since that was going to take three days, I thought I better button up the case (I have a three year old).  I stopped it, did a safe shutdown, cleaned everything up...  put the case back together.

 

Fired it up again - and now it says that Disk 4 is Unformatted.  I'm given the option to Format it - but that's not really what I want to do (it has data on it).

 

Following this notes from Joe L (and the link to answer the prompts with the proper settings), I tried to fix it.  There weren't any errors or anything.

 

I rebooted the machine again, since it wasn't clear what to do after the "rebuild".  It booted just fine - still shows the drive as Unformatted.

 

Any ideas?

 

Thanks so much,

Been working on this WAY too many hours...

 

Pulled that drive from the array too...  three drives lost in short succession... seems unlikely.

 

I realize the parity drive will now have useless data - I can hope that someday I might have the time/patience to try to reconnect the other two drives and see if I can pull files off them.

 

Rebuilding array now.

 

Planning new hardware purchase - I'll probably try these two drives with new hardware (have advice for new build - please share here:  http://lime-technology.com/forum/index.php?topic=41891.0)

 

Thanks,
