Hello
Created an erasure code pool in ceph , but cannot work with it in proxmox.
I simply used RBD(PVE) to moint it.
The pool can show up under proxmox correctly, with size as well, but cannot move disk to there:
create full clone of drive virtio0 (hdd:vm-100-disk-1)
error adding image to directory: (95) Operation not supported
TASK ERROR: storage migration failed: error with cfs lock 'storage-backup_erasure': rbd create vm-100-disk-1' error: error adding image to directory: (95) Operation not supported
I also cannot create VM to it:
rbd: create error: (22) Invalid argument2018-07-04 16:57:35.778203 7fc5627fc700 -1 librbd::image::CreateRequest: 0x561876d2cb90 handle_validate_overwrite: pool missing required overwrite support
TASK ERROR: create failed - error with cfs lock 'storage-backup_erasure': rbd create vm-107-disk-1' error: rbd: create error: (22) Invalid argument2018-07-04 16:57:35.778203 7fc5627fc700 -1 librbd::image::CreateRequest: 0x561876d2cb90 handle_validate_overwrite: pool missing required overwrite support
But if i run rados to test, it is totally fine:
root@ceph1:~# rados -p backup_erasure bench 20 write -t 32 -b 4096 --no-cleanup
INFO: op_size has been rounded to 12288

What can i do here with this case?
Thanks
