July 15, 20205 yr tl;dr qcow2 and very large data img file do not open and the backups were happening but have been incomplete. Who can I contact to potentially recover/read data from .img? I'm in a bad situation as this is a production server. I hadn't realized our NextCloud VM's had moved to the cache, it's 1.1TB. Over the weekend one of my cache drives from a pool took a dive. It looks like it was a faulty cable. I moved the cache drives to new cables to see if that would resolve the issue and the third disk kept throwing errors. I believe the drive had failed. Shut down the unraid, switched out the failed with a new drive. One of the other drives were also throwing an error. I tried a reboot. The cache pool was saying it knew the file system was BTRFS, but unmountable. I tried usiing the BTRFS restore techniques, to varying degrees of success, but the VM's that I copied weren't working or opening. The logs were showing that it needed to use mirrors to pull the data. The VM's still won't open. I tried the BTRFS check repair... last resort. Still nothing. I rebooted. The pool mounted, but it is not writable, which I suppose is a good thing. The mover doesn't work. I've been able rsync items from the pool, but the VM qcow2 and imgs don't work. qemu-img info for the boot drive /mnt/disk12/restore07152020_2/mnt/user/domains/NextCloudUbuntu1604/vdisk40G.qcow2 file format: qcow2 virtual size: 40 GiB (42949672960 bytes) disk size: 38.3 GiB cluster_size: 65536 Format specific information: compat: 1.1 lazy refcounts: false refcount bits: 16 corrupt: false fdisk -l for the drive /mnt/disk12/restore07152020_2/mnt/user/domains/NextCloudUbuntu1604/vdisk40G.qcow2: 38.3 GiB, 41119842304 bytes, 80312192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes No partitions, no anything. I've been at this for days and I am unable to go any further. Please help or direct me to someone who can. tower-diagnostics-20200715-1026.zip
