[zfs-discuss] When Zpool has no space left and no snapshots
Dear ZFS Discussion, I ran out of space, consequently could not rm or truncate files. (It make sense because it's a copy-on-write and any transaction needs to be written to disk. It worked out really well - all I had to do is destroy some snapshots.) If there are no snapshots to destroy, how to prepare for a situation when a ZFS pool looses it's last free byte?
