Hi all
New to PM and Linux, but love the potential of it.
Whilst exploring possibilities
I inadvertently removed '/mnt/pve/data' from a partition.
When selecting this disk, it displays
unable to activate storage 'data' - directory is expected to be a mount point but is not mounted: '/mnt/pve/data' (500)

Can you please advise on how to resolve this.
Thx in advance
 
Please use code blocks. Do you just want to remove data or what is the question?
 
Well if you removed the partition/file system you can't just remount it so I'm not quite sure what to suggest here. You can remove the storage itself in Datacenter > Storage. If guests reference the storage you need to remove those references first. What was the storage used for?

I suppose you can remove the reference directly from the config files try this to find them
Bash:
grep -sR "data:" /etc/pve
Or maybe you can restore a backup to another storage. Hard to say.
