Display info "Operation not supported" when backup VM on Proxmox

[Brother Twin]

Hi all,

i want to setup backup for all VM on Proxmox. After finished setup in the "backup job". it display many infor "operation not supported" for all VM:

For example:

Hi,

this happens if you storage do not support snapshots!

What storage type do you use?

 

[Brother Twin]

hi,

Storage type: NFS
nfs: snaplxc
export /mnt/cloudmedia
server x.x.x.x
path /mnt/pve/snaplxc
options vers=3
maxfiles 2
content vztmpl,iso,backup

it happen with VM/CT that is running for long time. When i create a new VM, i can do backup with mode snapshot without "info:....operation is not supported"

thanks.

Is the NFS the backup storage or the VM/CT disk storage or both?

 

[Brother Twin]

We use Freenas connect to Proxmox server via NFS type. Freenas is backup server.

i setup the storage and backup in tab "datacenter" to put all VM/CT backup file to backup server.

Can you please send me the output of 'lsblk',
and also '/etc/pve/storage.cfg'?

Hi,

I have the same error! i configure a nfs share via the proxmox web gui. in ovh forums i read that manual mount nfs share via console, and create a directory storage in proxmox work... but why are the proxmox option does not work? i have the same config like "Brother Twin". Any idea?

i have a error message like:

INFO: "....." failed: Operation not permitted (1)

maybe this is why the parameter no_root_squash is not set!? how we can set this?

 

[wolfgang]

Do I understand this correct you make a Backup in snapshot mode from a zfs storage to a NFS storage and after a while you get this error?

@OliverB this problem is a different one

 

[redjohn]

Okay, and what can i do to fix this issue with failed: Operation not permitted (1)?

 

[Brother Twin]

Hi Wolfgang,

yes, you are right. i got many "INFO: ...................: Operation not supported" when i did the backup for VM/CT running for a long time.
