I have several samba shares, one of which is used for storing some backups.
I want to set a disk space quota on said share, as the ZFS volume the share resides on is huge and multi-purpose... I don't want the backups taking up more than 20Tb.
Can anyone point me in the right direction on how I can achieve this?
Thanks in advance!
To set the quota for a filesystem:
zfs set quota=20TB poolname/backup-filesystem
To query the current quota setting:
zfs get quota poolname/backup-filesystem
Note that quotas can only be set on ZFS filesystems (i.e. made with zfs create pool/fsname), not on subdirectories (made with mkdir).
subdirectories of a ZFS filesystem are included within that filesystem's quota usage. Child filesystems inherit their parent's quota (if any) unless overridden with their own zfs set quota=size pool/parent/child command (but this is an additional restriction - child filesystems, like snapshots, are included in the parent's total quota usage).
