yippy3000 Posted February 25, 2018 Posted February 25, 2018 My log files just filled up with what looks like errors. Anyone have any idea what it means, kind of looks like filesystem issues. sdc is one of my 2 SSD Cache drives and I tried running SMART self tests on it but when I click start the button just flashes and does nothing. aeris-diagnostics-20180225-0710.zip
yippy3000 Posted February 25, 2018 Author Posted February 25, 2018 In the last two days I have also gotten the following emailed to me once a day. I am betting it is related: Email Subject: cron for user root /sbin/fstrim -v /mnt/cache | logger &> /dev/null Email Body: fstrim: /mnt/cache: FITRIM ioctl failed: Input/output error
JorgeB Posted February 25, 2018 Posted February 25, 2018 Cache2 dropped offline, check cables and run a correcting scrub, check that there are no uncorrectable errors.
yippy3000 Posted February 26, 2018 Author Posted February 26, 2018 Now my cache is starting read only after reboots (NOTHING in Unraid tells me this or that anything is wrong, I have to try to write to it via SSH to know this). New diagnostics after the latest reboot. I am guessing either one of the cache drives died (passing extended smart tests but looks like it might have a new unnallocated sector count that was successfully moved) or the btrfs corupted itself. aeris-diagnostics-20180226-0918.zip
JorgeB Posted February 26, 2018 Posted February 26, 2018 sdc is corrupt for being offlined, you should still be able st mount the cache if you temporarily physically disconnect sdc, if it mounts OK then wipe sdc and re-add to pool.
yippy3000 Posted February 26, 2018 Author Posted February 26, 2018 My whole cache seems to be hosed. BTRFS is doing some serious crunching on something right now after I removed the questionable drive from the cache pool. Will see if that ever comes back up up with a single drive or if I need to rebuild everything (I have backups!). Still don't know if the drive is bad though but suspecting it might be.
