HELP!!!! BTRFS unmountable after power loss.

Help.  I had a power problem and was shutting down the server when my UPS died.  I rebooted the server and the array started but the cache was unmountable.  I have 3 SSDs in BTRFS.  one of the drives was in a list of drives to format, after looking all around i decided that since the other drives were not listed, that i would format that and see if that would bring the cache back.  well it mounted, but all files are gone.  I have no backups of the VMs or Dockers.  Please HELP! 

 

i tried running "btrfs restore -v -i /dev/sdi /mnt/user/Software/cacherestore" and that gave me

"No valid Btrfs found on /dev/sdi

Could not open root, trying backup super

OK i have run "btrfs restore -v -i /dev/sdi /mnt/disks/OCZ_ARC100_A22L2061519000807/sdi"

 

that restores some files, but it looks like new files and only about 57MB.

 

I dont know what else to try.  im really in a binde.

I have my array in Maintenance mode right now and not writing anything to disks.  I have a feeling all my data is gone.  im really really hoping JonP can come through with something or someone else.  I had all my VMs, Dockers and other stuff on there.
