So, the hostname of one of our zones changed, and we create ZFS file systems for
the zones using path/zonename
Easy enough of a fix...
$ zoneadm list -cv
ID NAME STATUS PATH BRAND
IP
0 global running / native
shared
1 blah running /local2/data/zones/blah native shared
5 blah1 running /local/data/zones/blah1 native
shared
$ zonecfg -z blah1
zonecfg:blah1> set zonename=blah2
blah1: Zone state is invalid for the requested operation
So lets shut down the zone and change the zone name.
$ zoneadm -z blah1 halt
$ zonecfg -z blah1 info
zonename: blah1
zonepath: /local/data/zones/blah1
$ zonecfg -z blah1
zonecfg:blah1> set zonename=blah2
zonecfg:blah2> verify
zonecfg:blah2> commit
zonecfg:blah2> exit
So now that we've changed the zone name, I also wanted to update the ZFS file system to reflect the new hostname...
$ zfs rename pool0/local/data/zones/blah1
pool0/local/data/zones/blah2
Easy enough. Lets boot the zone.
$ zoneadm list -cv
ID NAME STATUS PATH BRAND
IP
0 global running / native
shared
1 blah running /local2/data/zones/blah native shared
- blah2 installed /local/data/zones/blah1 native shared
$ zoneadm -z blah2 boot
zoneadm: /local/data/zones/blah1: No such file or directory
could not verify zonepath /local/data/zones/blah1 because of the above
errors.
zoneadm: zone blah1 failed to verify
DOH. Forgot to change the zone path.. So lets go fix this...
$ zonecfg -z blah2
zonecfg:blah2> set zonepath=/local/data/zones/blah2
Zone blah2 already installed; set zonepath not allowed.
WHAT?!?! Come on now zonecfg, this shouln't be brain surgery....
So, lets go poke at the source of truth -- /etc/zones.
$ grep blah1
index:blah2:installed:/local/data/zones/blah1:6b9891a3-7029-ef67-9581-aa01475c9b
6e
blah2.xml:<zone name="blah2" zonepath="/local/data/zones/blah1"
autoboot="true">
So, go and edit blah2.xml to change the zone path, as well as index. (Make backup copies of these before doing so please)
Once the modifications were done, I was able to boot up the zone with the newly changed zonepath.
$ zoneadm list -cv

Sun, could we please extend zonecfg to do this for us? The header of /etc/zones/index is scary.
