jvlarc Posted January 31, 2022 Share Posted January 31, 2022 Hi guys, just installed a new 128gb nvme drive to be used for VM into my unraid server, however on auto startup, Something seems to have merged my 2 existing 500GB Cache drive into a 960GB pool and is currently running a BTRFS Balance. Looking at the disk log, it shows devid 2 is missing. Was asking on Discord and was advised that I should post it here as it may be a possible bug. Will be trying to restart the system shortly after the balance is completed. Attached is my diagnostic file. Have currently changed my shares to 'Yes' to slowly move them off the cache drives first before switching to 'No' and reboot. I do have CA Backup/Restore running but just to be safe tower-diagnostics-20220131-1236.zip Quote Link to comment
jvlarc Posted January 31, 2022 Author Share Posted January 31, 2022 Update - the entire array hang after awhile and I just hard restart the server and seems to ask me to rebalance the pools first. ran this command Quote btrfs fi df /mnt/cache Data, RAID1: total=15.00GiB, used=10.97GiB Data, single: total=311.00GiB, used=233.32GiB System, RAID1: total=32.00MiB, used=0.00B System, single: total=32.00MiB, used=80.00KiB Metadata, RAID1: total=1.00GiB, used=131.83MiB Metadata, single: total=3.00GiB, used=491.55MiB GlobalReserve, single: total=288.73MiB, used=16.00KiB WARNING: Multiple block group profiles detected, see 'man btrfs(5)'.

JorgeB Posted January 31, 2022 Share Posted January 31, 2022 Looks unrelated to the new device, what happened to the other cache device? Balance is because there's a missing device and the log you posted ends during the balance without any errors for that that I can see, though btrfs is detecting corruption on multiple filesystems, so you likely have some hardware issue like bad RAM, and if the balance crashed after it's possibly because of that, start by running memtest.

jvlarc Posted January 31, 2022 Author Share Posted January 31, 2022 Hi JorgeB, Just took the other cache drive out of the system and plugged into my pc, I guess the SSD died as it's not being detected anymore on my system. Can I check how to tell the errors from the btrfs corruption? Anyway I've managed to restore the appdata and everything seems to be back up running normally again. I shall run a memtest within the next few days... really hoping I do not have bad ram again as it was a few months ago and replaced it Quote Link to comment
