2Piececombo Posted April 6, 2021 Share Posted April 6, 2021 I have 2 vms which reside on the cache pool (2 nvme drives) today they both stopped working and I cannot restart them, I receive an error that the file system is read-only. On the main tab the cache shows plenty of space left, but the number of writes is 0 (reads looks normal) Diags are attached. Any help is greatly appreciated! floserver-diagnostics-20210406-1530.zip Quote Link to comment
2Piececombo Posted April 6, 2021 Author Share Posted April 6, 2021 I rebooted the server, and now neither cache drive is showing, I've had this problem before, see this thread. I went a while without issue, but seems to be back to the same problem again where the cache drives don't show up. Quote Link to comment
2Piececombo Posted April 6, 2021 Author Share Posted April 6, 2021 After rebooting the server 4 times, they are again showing up, but as unassigned devices. Quote Link to comment
JorgeB Posted April 7, 2021 Share Posted April 7, 2021 Apr 4 04:40:03 floserver kernel: BTRFS error (device nvme0n1p1): error writing primary super block to device 2 Syslog doesn't cover the beginning of the problem but this suggests NVMe devices are dropping offline, see here fore better pool monitoring. Also post new diags after the reboot. Quote Link to comment
