Dmtalon Posted April 1, 2018 Share Posted April 1, 2018 (edited) Build is a few years old now, has been rock solid, until recently. I have had 2 VM's (windows 7 and windows10) and a Plex docker. The windows 7 VM runs my "house audio" via a pass-through audio PCI card, and also runs uTorrent. First sign of issues, is extracted RAR files either being empty (extraction failed), or corruption (or what I thought was corruption). I had 5 data drives, 1 parity, cache and an app drive. Cache drive is a fairly old 1TB WD Black, app drive is a samsung 128GB SSD. VMs/Dockers live on the app drive, and downloads would download to the VM, then copy to a directory (through cache). I assumed my cache drive was dying even though no red ball, and decided to move into 2018 and dump the separate cache/app drive and put in a 500GB SSD as my cache/app drive. That all went fairly smooth, however one of my VM's didn't want to come up. I messed with it for a while, but eventually plugged the old app drive into another pc (booted upbuntu usb live) and tried copying over the vm again. I did this and boom, VM came up. Fast Forward, uTorrent (or some process) was still having issues. I decided since I had a nice new big cache/app drive to install ruTorrent docker, Got that up and running and added some existing recent torrents to it pointing to there already downloaded location. It was here I discovered that uTorrent didnt' seem to be completing the downloads. ruTorrent was finding them at like 96-97% complete and then finishing them. So, I assumed that this was just some kind of uTorrent issue, and moved on with life using ruTorrent docker vs uTorrent on my VM. It was this same time I discovered pi-hole and pi-hole docker so I installed and got that working/setup too. SO I'm feeling all good and things are working etc.. Yesterday my VMs/Dockers crashed, and i had all kinds of I/O errors in my logs. So I SSH in and try to look in /mnt/cache but no go, i/o errors. OK, lets shut down the array go into maintenance mode and do some checks. BUT, I can't get /mnt/cache unmounted. I let it sit, I tried lsof/fuser etc.. but the kernel was the only process that seemed to have it locked, so I pulled the plug and rebooted. Everything came up but Parity wanted to run. I stopped it, stopped the array, and put it in maintenance mode. I wanted to do some checks on the cache drive. It seemed to find some errors it couldn't fix (and google didn't help me a whole lot honestly) "Metadata CRC error detected at xfs_bmbt block" Phase 1 - find and verify superblock... Phase 2 - using internal log - zero log... - scan filesystem freespace and inode maps... - found root inode chunk Phase 3 - for each AG... - scan and clear agi unlinked lists... - process known inodes and perform inode discovery... - agno = 0 Metadata CRC error detected at xfs_bmbt block 0xec53a00/0x1000 Metadata CRC error detected at xfs_bmbt block 0xec53a00/0x1000 btree block 1/451648 is suspect, error -74 - agno = 1 - agno = 2 - agno = 3 - process newly discovered inodes...

Phase 7 - verify and correct link counts... done After trying to run xfs_repair w/o -n and ultimately with -L those errors stay, so I restarted the array and let it run a parity check through the night. It found 2.4 million errors. and when I just took the array offline (stopped, restarted in maintenance mode to get the errors above) it told me I had an unclean shutdown and needed another parity check. I'm attaching some screen shots, and a diagnostics report from just now after the parity. Before I keep digging in this hole I'm in, I'm hoping someone can maybe help me climb out. Thanks, sorry for the rambling. nas1-diagnostics-20180401-1056.zip Edited April 1, 2018 by Dmtalon Quote Link to comment
JorgeB Posted April 1, 2018 Share Posted April 1, 2018 Corrupt cache filesystem and parity sync errors to me suggest a hardware problem, I would start by running memtest for a few hours, ideally 24 Quote Link to comment
Dmtalon Posted April 1, 2018 Author Share Posted April 1, 2018 So, I cleaned up the cache drive, formatted it clean and deleted the libvirt image and started fresh. Started installing windows again fresh. While trying to install a service pack I see this pop up in the logs. No indication there were any issues until just now. (no errors in log) I shut everything down, and reseated the ram, and am running memtest86 on it. We'll see what happens I guess.

Dmtalon Posted April 3, 2018 Author Share Posted April 3, 2018 So, as an update. I let memtest run 4 tests (about 19 hours) and it found no errors. I've decided to try going back to my previous build of unRAID (6.3.5) (did a full restore of the zip I took before upgrading). Put my app drive and cache spinner back in, and rebooted. I copied off the date from the app drive, cleaned it up by reformatting it, then moved my VM/Dockers back on. Things seem back up, and no errors in the log(yet). I'm about 20% through a parity check now. Once that completes I'll try some tests load tests within the VM to see if the problem returns. I'm starting to wonder if it's a 6.5.0 issues, but time will tell I guess. Quote Link to comment
