storage backup is not online error

[Diana92]

Hi guys

I want to get backup of web server, I mount a NFS share, install nfs server for windows, make share with this backup, then configure on proxmox server

[B]mount -t nfs -o vers=3 xxx.xxx.xxx.xxx:/c/shared_folder[B]/mnt/nfs [/B][/B]

My /etc/pve/storage.cfg

nfs: backup
	path /mnt/pve/backup
	server 192.168.168.28
	export /mnt/pve
	options vers=3
	content backup
	maxfiles 1

Then I try to browse the content in proxmox GUI, and get error storage 'backup' is not online (500).
What I'm doing wrong? Could anybody help?

your export 'export /mnt/pve' looks wrong. Try 'export /c/shared_folder' instead.

nfs: backup
path /mnt/pve/backup
server 192.168.168.28
export /c/shared_folder
options vers=3
content backup
maxfiles 1

nothing changed, except storage.sfg file
storage 'backup' still not online

Is that share name correct? What is the output of

# showmount --exports 192.168.168.28

Is that share name correct? What is the output of

# showmount --exports 192.168.168.28

Yes, it's correct. It's the name of folder which is in C.

Output of showmount --exports 192.168.168.28
rpc mount export: RPC: Procedure unavailable
