Hello,
I have the following situation:
1) A ZFS filesystem, created with zfs create:
- multipack/u01
2) Data created in said filesystem
3) A snapshot taken of this filesystem:
- multipack/[EMAIL PROTECTED]
4) A clone filesystem created from the snapshot:
- multipack/u09
multipack/u01 41.5K 57.9G 24.5K /multipack/u01
multipack/[EMAIL PROTECTED] 17K - 24.5K -
multipack/u09 20.0M 57.9G 20.0M /multipack/u09
I discovered that if I had a regular user in the /multipack/u09
directory (ksh) and I try to rollback multipack/[EMAIL PROTECTED] I get the
following error:
cannot unmount '/multipack/u09': Device busy
OK, so I get the reason behind this message but I do not understand
why we're unmounting the clone filesystem in the first place?
Surely the filesystem is based on the read-only point in time snapshot
which isn't changing. Anything I add to this filesystem or delete
won't affect the snapshot or the origin, multipack/u01 ... so why are
we attempting to unmount it for a rollback?
Many thanks in advance,
Jason
