What happens with a overfilled quota ?

Post by drnicolas »

I have several zfs-dataset also used as cifs-shares.
All of them have quotas associated, such as 30gb or 10gb

What happens, if the content of data increases and reaches 100% quota ?

Are further addtions blocked ? Does the system crash ?

Can I "overquote" my ZFS (say 30g+30g+40g add to 100g but what if the ZFS is only 80g?)

It will deny writes when quota is reached.

I think I tried over provision quota a couple years ago and it let me. I don't remember what happened, but I would assume it would just show real free space and act like any file system when it's full, deny writes.
