Out of space snapshot

[Kyar]

Hello,

I want to make a snapshot of my VM but I have one error : "TASK ERROR: zfs error: cannot create snapshot 'RAID5/vm-100-disk-0@MASTER': out of space ".

My zpool list :

root@PROXMOX:~# zpool list
NAME    SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
RAID5  10.9T  2.96T  7.94T        -         -     0%    27%  1.00x    ONLINE  -

My zfs list :

root@PROXMOX:~# zfs list
NAME                  USED  AVAIL     REFER  MOUNTPOINT
RAID5                7.03T   113G      128K  /RAID5
RAID5/vm-100-disk-0  7.03T  5.17T     1.97T  -

How many space I need ?

Hello,

I guess you not enable the `thin provisioning` [0] on your ZFS. To know that you can provide us with the output of the following command:

cat /etc/pve/storage.cfg

Absolutly...
My storage was full since the beginning.

I didn't activate "discard".

I had to delete everything.

Thanks you
