September 16, 201411 yr This started in the last couple of months, and I've been putting off (living dangerously!) seeking help here for the problem. Server locks up every so often (a few weeks) and I have to do an unclean shutdown as it doesn't respond to any commands via console or web interface. When I mount the discs, of course it starts a parity check and then the system locks up again after 30 seconds or so. I can start up the array w/o doing the parity check and read data off all disks w/o an issue - I get 12 happy/green balls and no indication that anything is wrong - unless I have to do another unclean shutdown again and then we get the same issue. I'm sure I'm overdue for some sort of hardware failure - but would rather not just start replacing stuff randomly - was hoping someone had experienced the same thing and could point me in a (helpful) direction - thanks!
September 16, 201411 yr sorry - 5.0.5 system is locked up - can't get a syslog We can only guess if you won't provide any diagnostics. Check sata and power cables. Maybe bad drive, bad power, bad controller... Since you are going to power down to check the cables then maybe you can get a syslog before it locks up again.
September 16, 201411 yr Author I do appreciate the help Here's one I was able to grab from earlier in the day - hope something stands out! towerLog.txt
September 16, 201411 yr A problem, but not the likely cause of your lockup: Sep 16 13:39:52 Tower kernel: FAT-fs (sda1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck. Put the flash in your PC and run checkdisk. Also Sep 16 13:39:52 Tower emhttp: unRAID System Management Utility version 5.0-rc15 not 5.0.5 You might try the tail suggestion in the link I gave you and let it run until it locks up and see what we get. But first, reboot into memtest and let that run for a while.
September 16, 201411 yr Author not 5.0.5 Strange - that's what it says in the upper right corner of my console when it's running- No issues with chkdsk on flash drive that windows could find running memtest as we speak
September 17, 201411 yr Author Cautiously optimistic update- ran memtest last night for a few hours - didn't return any errors, but really slowed down to a crawl on a few of the tests. Since I had a couple of spare sticks lying around in a dead machine, I swapped them in and am now up to 35% on the parity check. (Before, the machine would lock up before even hitting 1%) I'm almost ready to call this one solved - thanks again for your help!
