I had the same problem with preclear , cach_dirs, and drives spinning up. Most of my storage is large video recordings, with one share containing many small files. I excluded the share with the small files from cache_dirs, and it fixed the problem.

But the real question is:
If you have a flash drive with a fully functional 4.7, labeled UNRAID, license key, disks configured, shares set up, etc.
And a flash with a fully functional 5.x,labeled UNRAID, license key, disks configured, shares set up, etc.
Can you shutdown a server under one OS, pull the flash, copy super.dat to the other flash, insert the other flash, and bring up the server under the other OS.
The goal is that both OS's are happy, no irregularities, and no rebuilding of the raid drive required under either OS. Is the super.dat file the only thing that needs to change when switching flash drives?
I would like to be able to switch back and forth several times before committing to 5.x, with minimal impact.

Got 2 keys when I bought my license.

Still running 4.7. I'd like to start building a 5.0 environment on a separate flash drive, and have the ability to go back and forth between releases. Is copying super.dat when switching flash drives all that's necessary?
I seem to remember that Tom said that it wasn’t a problem going back to 4.7 after newperms has been run.

Thanks for the great feedback.
Just for the record, I've included the previous syslog. A power outage from Hurricane Sandy forced the server down after 9 months. Other than a few media errors and a sporatic "frozen" error from the unresolved Barracuda 7200.11 firmware issues, nothing noteworthy.
UnRaid 4.7 has been so incredibly stable that I haven't wanted to upgrade. The price I paid was having to purchase another small (2TB) drive, and not having the luxury to wait for a good sale.
I'm looking forward to an equally stable 5.0 release.

It's in the zip file

This Server has been totally stable for 3 years.
An ST32000542AS red balled, and I’m pre-clearing a replacement. In the mean time, I’ve been testing the drive on another pc. Seatools for DOS comes up clean. The UnRaid MyMain Smart web page looks good. Smartctl doesn’t show anything critical.
I’m wondering if the problem is the drive or some other component.
The end of the Syslog shows the drive failure.
4.7 final, C2SEE w/drive on the internal controller, Celeron 1400, 4GB, Corsair VX450, (1) SIL3132 PCIx SATA controller, Intel PCI NIC, 7 drives in total.
-
Not a good idea. Some linux kernels unlock the HPA.
Set the drive to 2TB with HDAT2 and verified after a power off. Booted UnRaid RC8a, and it saw a 3TB drive.
Figured if I ever wanted to upgrade from 4.7 to 5.0, I should stay away from mucking with the HPA.
Anyone holding off for 5.0 Final will have to bite the bullet and buy 2TB drives if you have a drive failures. Wish I upgraded earlier.
-
I have a 3TB drive that went through multiple Pre-Clear passes on a test 5.0 system. I'd like to use the HPA trick to reduce the size to match the 2TB drive, then use it to replace the failed drive. Its on the on-board controller on a C2SEE, so I wouldn't expect controller problems. Anyone see potential problems?

My compromise for minimizing power cycles - l keep all drives set to manual and spin everything down at bed time. Whenever they spinup, they stay that way for the rest of the day.
Does anyone have a script that changes the spindown delay depending on the time of day?
-
Are you single?
Nope..
That seems like a very interesting option. As much as I don't mind kludging stuff.. I think that is going a bit too far for me. lol..@aim60 The cheapest on ebay is just a couple bucks less than GPS, but probably will go with your link. How long have they lasted?
Battery Geek seems to be the cheapest on ebay:
http://cgi.ebay.com/RBC25-UPS-Battery-Pack-SU1400RMXL3U-RBC8-RBC23-RBC24-/200468876592
$52 shipped, versus GPS is $56 shipped. Also, battery geek is 0.5 ah higher, but not sure that is that big of deal for me.
Thanks,

They lasted 3 years.
The first set they sent were their own private label batteries. Their replacements, 3 years later, were another brand. These guys refurb large (as in pallet jacks and fork lifts) UPS's, so I figured they wouldn't risk their reputation selling junk.
Toured a large datacenter the other day. They used [uPS's] without batteries. Utility Power -> [electric motor -> large flywheel -> generator] -> load. In case of a power outage, the flywheel keeps the UPS going long enough for diesel generators to kick in and replace utility power. Great idea for anyone that has a diesel generator at home that can kick in in 5 seconds.
-
I've had good service from these guys
http://stores.ebay.com/Gruber-Power-Services
but shipping on a Back-Ups 1000 battery was as much as the battery.
Still a good bottom line price, but it hurts that 50% of my dollars went to UPS.

Interesting...Running preclear_disk version 1.7 on unRaid 5.0 Beta6a. The default partition format is 4K aligned. Called with
"preclear_disk -c 2 /dev/sdc" (no -a or -A). Cycle 1 ran with partition start 64. Cycle 2 is running with partition start 63.
I don't doubt you, but I see no way for that to occur... (In other words, I'll have to test it myself)
If running with no option specified the "default" will be that you've specified in the unRAID "Settings" page.
The partition start is set prior to entering the "cycle" loop. It is un-changed (as far as I know) otherwise.
Before I start my test, are you sure you have 4k-aligned as the "default" set on your server? (please double-check, so I can duplicate your situation here)
Also, once the second cycle is complete, let me know what the output says. You might even run
preclear_disk.sh -t /dev/sdc
and let it tell you how the disk is partitioned. I'll be curious what it says.

The default is 4k-Aligned. I'll run -t when the cycle is done. Also, the server isn't needed at the moment. I'll repeat the 2-cycle test to verify. Any files that would be of use?
Should have done more verification before posting.
What I encountered was the bug that you fixed in version 1.9 (preclear defaults to 63 sector alignment on unRaid 5 with no -a or -A).

Joe, running preclear_disk version 1.7 on unRaid 5.0 Beta6a. The default partition format is 4K aligned. Called with
"preclear_disk -c 2 /dev/sdc" (no -a or -A). Cycle 1 ran with partition start 64. Cycle 2 is running with partition start 63.
If its significant, there are no disks assigned to the array.

I'm currently running horizontally without backplanes. But my CM590 is filling up, and I'll need to consider 5-in-3's or a Norco. I've heard that switching a HD's orientation after months or years of bearing wear is an invitation to premature failure. Any feelings?

The first hard drive that I worked on used these platters.
http://www.grandideastudio.com/portfolio/hard-drive-coffee-table
The platters were mounted vertically on a horizontal spindle. A byte was written in parallel, one bit on each platter surface.
There was a story that during maintenance, with the cabinet opened and the drive running, that the spindle broke loose from its mounting. Rolled across the floor and almost killed someone.

Had a wireless keyboard dongle hanging out of the back of my HTPC. Moved the PC, smacked the dongle on a wall, and almost broke it in two.

No, unRAID only supports the first NIC it finds.
Peter
Perhaps a better terminology is the unRAID only uses the first NIC it finds. You can set up the second NIC however you like manually.
For us linux n00bs, could you list the commands to setup the second nic.
-
Already spent a week testing the drive. Better to follow your recommendation and RMA it.
Thanks

From:
'Warning: ATA error count 9 inconsistent with error log pointer 5' What's the meaning of this smartctl message?
The ATA error log is stored in a circular buffer, and the ATA specifications are unambiguous about how the entries should be ordered. This warning message means that the disk's firmware does not strictly obey the ATA specification regarding the ordering of the error log entries in the circular buffer. Smartmontools will correct for this oversight, so this warning message can be safely ignored by users. (On the other hand, firmware engineers: please read the ATA specs more closely then fix your code!).

I have a 4 month old 2TB EARS drive that’s been running in the array without problems (4.5 Final, jumper installed). After a parity check, it showed 19 pending sectors. After a second parity check the count increased to 49. I swapped the drive out, moved it to a test server (4.7 Final), and ran 5 Preclear passes. Ever since the end of the first pass, Smartctl has shown 0 pending sectors and 0 reallocated sectors.
The syslog from the test server shows several hardware errors on the drive, probably during the first preclear pass.
I’ve also run WD’s DataLifeGuard long diagnostics and Smartctl long tests. Neither has shown any errors.
Should I RMA the drive or put back into the array?

CyberPower 1500VA UPS $130
in Good Deals!

If you are planning on using the APCUPSD plugin with a CyberPower, read this.
http://lime-technology.com/forum/index.php?topic=13411.msg127182#msg127182
The plugin shuts down unraid without a problem. Suggest setting "Power Down UPS after shutdown" to NO, and dedicating the UPS to unraid.
On my CP1500PFCLCD, if you set it to YES, the UPS doesn't shutdown when you would expect it to. At power fail, it sets an internal 60 minute timer, and shuts down the UPS when the timer expires. And the timer doesn't reset if utility power is restored! If you power up the server before it expires, be prepared for an unexpected server crash. A manual power cycle of the UPS will clear the timer.
There's an alternative to APCUPSD that seems to have Cyberpower compatibility. No idea what it would take to get it running under unraid.
