dangerbees Posted February 2, 2020 Share Posted February 2, 2020 My array shows all online drives, but does not see any filesystems. I tried to switch to a different SAS controller, and I fear everything is gone. Which is sad. Is there a way I can scan for a filesystem, or at least my files? ower emhttpd: shcmd (30): /sbin/btrfs device scan Feb 1 18:47:50 Tower root: Scanning for Btrfs filesystems Feb 1 18:47:50 Tower emhttpd: shcmd (31): mkdir -p /mnt/disk1 Feb 1 18:47:50 Tower emhttpd: /mnt/disk1 mount error: Unsupported partition layout Feb 1 18:47:50 Tower emhttpd: shcmd (32): umount /mnt/disk1 Feb 1 18:47:50 Tower root: umount: /mnt/disk1: not mounted.

JonathanM Posted February 2, 2020 Share Posted February 2, 2020 Post diagnostics zip file. I suspect, as long as parity is valid, that you could pull 1 disk at a time to force Unraid to emulate the drive and it would mount. If that's the case, you could rebuild the drives one at a time. However... I wouldn't risk doing that without knowing more about what happened, and what state the array is in right now. How is your backup situation? Quote Link to comment
dangerbees Posted February 2, 2020 Author Share Posted February 2, 2020 it will start the array, and no mountable filesystem exists. no drive has any files. backups.... well, I suppose probably, mostly. yeah. still would rather get this back running. Quote Link to comment
JorgeB Posted February 2, 2020 Share Posted February 2, 2020 This can happen when changing from RAID controller to HBA (or vice versa), since partitions are outside parity it's usually possible to rebuild the disks one at a time (or two if you have dual parity) on top so Unraid recreates the partition, test first by unassigning one of the data disks, then start the array, if the emulated disks mounts correctly you can rebuild on top, when rebuild is done repeat for the other disks.
