With 'zfs rename'subcommand we can do than renaming the file system.
We can accomplish the following operations:
For relocating the file system the following conditions must be satisfied:
Examples:
I have the following ZFS file system hierarchy under the pool ztest:
root@solarislab:~# zfs list -r ztest
NAME USED AVAIL REFER MOUNTPOINT
ztest 302K 976M 32K none
ztest/z1 124K 976M 31K none
ztest/z1/z2 93K 976M 31K none
ztest/z1/z2/z3 62K 976M 31K none
ztest/z1/z2/z3/z4 31K 976M 31K none
We can accomplish the following operations:
- Change the file systems' name
- Relocate the file system within ZFS hierarchy.
- Rename the file system & relocate it within ZFS hierarchy.
For relocating the file system the following conditions must be satisfied:
- The file system can be relocated in the hierarchy of the same pool.
- If there are quota/reservation properties set then there must be enough space available in the destination location in the hierarchy to complete the move operation.
Examples:
I have the following ZFS file system hierarchy under the pool ztest:
root@solarislab:~# zfs list -r ztest
NAME USED AVAIL REFER MOUNTPOINT
ztest 302K 976M 32K none
ztest/z1 124K 976M 31K none
ztest/z1/z2 93K 976M 31K none
ztest/z1/z2/z3 62K 976M 31K none
ztest/z1/z2/z3/z4 31K 976M 31K none
Now to rename z4 to z5 type the following:
root@solarislab:~# zfs rename ztest/z1/z2/z3/z4 ztest/z1/z2/z3/z9
root@solarislab:~#
root@solarislab:~# zfs list -r ztest
NAME USED AVAIL REFER MOUNTPOINT
ztest 304K 976M 32K none
ztest/z1 124K 976M 31K none
ztest/z1/z2 93K 976M 31K none
ztest/z1/z2/z3 62K 976M 31K none
ztest/z1/z2/z3/z9 31K 976M 31K none
ztest/zfstest 31K 976M 31K /test
To move z9 file system from its current location to immediately after z2 in the hierarchy, type:
root@solarislab:~# zfs rename ztest/z1/z2/z3/z9 ztest/z1/z2/z9
root@solarislab:~# zfs list -r ztest
NAME USED AVAIL REFER MOUNTPOINT
ztest 304K 976M 32K none
ztest/z1 124K 976M 31K none
ztest/z1/z2 93K 976M 31K none
ztest/z1/z2/z3 31K 976M 31K none
ztest/z1/z2/z9 31K 976M 31K none
ztest/zfstest 31K 976M 31K /test
