April 17, 20242 yr Hi, Made a rookie misstake and now all my vms are gone. A few days ago I powered down my unraid box and installed a geforce graphics card, my thought was that I could start a new VM and try to run some games through steam link on it. While mucking around I accidentally disconnected one of the sata cables to one of my ssds in a btrfs pool of 2 that hosts all my (5) VMS. The system started as usual after the graphics card install and I thought that I was just going to let the Parity-Check go through and in the meantime I could start testing with the new VM before restarting and plugging in the ssd. As if that wasn't enough it seems that we had some kind of power outage during the parity check and when I got the chance to plug the disconnected cable again and start unraid again both ssd devices in the pool are down. Is there some way to recover from this? jehq-diagnostics-20240417-2109.zip Edited April 17, 20242 yr by U1elm Added diag zip and print screen

April 18, 20242 yr Community Expert Pool is apparently OK, could be related to v6.9, unmount the pool with umount /x Then upgrade to v6.12.10 and post new diags after array start if it still fails to mount

Since the pool is OK, would it be possible to copy the .img files to the array as a backup before trying to upgrade? best regards, U1
April 18, 20242 yr Community Expert You can start the array to copy somewhere else, the VM pool will still show unmoutable, but the data will be under /x

Used Krusader to backup the .img files to array and will start with 6.12.10 upgrade soon. With the backup done, worst case is just to re-format the vm pool. I'll post back after upgrade if it still fails to mount. Thanks again.
