i have 3x 10tb disks in my server, and one of the three was dedicated solely to my plex media (for now). i had a lvm thinpool and stupidly created a drive in the thinpool for 10tb (which was too big, obviously). now i've filled the drive and am getting io errors, and can't reactivate it. i also can't repair it because there's no space left on the disk.

how can i fix this and get the data off the disk if i need to format and start over? i have enough room elsewhere to copy files to if i can get them mounted, but i've had no luck figuring out how to get the drive activated and mounted to get the data off of it and move it elsewhere...
 
i was able to extend to a usb stick, but i can't get the lvms to activate...

# lvchange -ay pve2/vm-107-disk-0

device-mapper: resume ioctl on (253:26) failed: Invalid argument

Unable to resume pve2-data2-tpool (253:26)

can anyone assist me in getting these activated so i can get data off them and fix everything?

i tried the solution from here:
https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1625201

Code: 
thin_dump /dev/mapper/vg02-pool0_tmeta > lvm_meta_dum
lvcreate -n pool0meta2 -L 12G vg02
thin_restore -i lvm_meta_dump -o /dev/mapper/vg02-pool0meta2
lvconvert --thinpool vg02/pool0 --poolmetadata vg02/pool0meta2

as my meta was initially 16gb and i've been seeing the same errors in dmesg...but that didn't work either. i still get the error above (invalid argument) if i try to activate the vg...

if i try to activate the lv, i get this (after trying the manual meta recreation from the link above)...

Code: 
lvchange -ay pve2/data2
  device-mapper: create ioctl on pve2-data2_tmetaLVM-Zg3oPyGdhFhGZJ7ixqUTMLj61ITjaVbGPVQK6r202WVHBIH12Ds2RjEKeVYWIB98-tmeta failed: Device or resource busy

I cannot give any more advice. In case of a restore it may be recoverable or it may not.

Have you considered to buy a subscription and get help from the Proxmox staff?

i hadn't, but that's a good point. maybe i'll try that and see if anyone can assist.

edit: actually, nevermind. i didn't realize i needed to get the second level subscription to get support from the staff...$300 isn't something i can afford right now.
 
is there anyone else out there that can help me get this data back, or am i screwed and just need to start over? i'm getting incredibly frustrated, nothing i have tried works and nobody online seems to be able to help with any of this...
