Arjun,
Yes, you an choose any name for the root pool, but an existing
limitation is that you can't rename the root pool by using the
zpool export/import with new name feature.
Too much internal boot info is tied to the root pool name.
What info are you changing? Instead, could you create a new BE
and update the info in the new BE.
Creating a new BE is the best solution.
Another solution is to create a mirrored root pool and then use the
zpool split option to create an identical root pool (that is then
imported with a new name, like rpool2), but this identical root pool
won't be bootable either. You would then need to mount rpool2's file
systems and copy whatever data you needed.
Thanks,
Cindy

Hi,
Let me add another query.
I would assume it would be perfectly ok to choose any name for root
pool, instead of 'rpool', during the OS install. Please suggest
otherwise.
Thanks

Hello,
I have a situation where a host, which is booted off its 'rpool', need
to temporarily import the 'rpool' of another host, edit some files in
it, and export the pool back retaining its original name 'rpool'. Can
this be done ?
Here is what I am trying to do:
# zpool import -R /a rpool temp-rpool
# zfs set mountpoint=/mnt temp-rpool/ROOT/s10_u8
# zfs mount temp-rpool/ROOT/s10_u8
### For example, edit /a/mnt/etc/hosts
# zfs set mountpoint=/ temp-rpool/ROOT/s10_u8
# zfs export temp-rpool --> But, I want to give temp-rpool its
original name 'rpool' before or after this export.
I cannot see how this can be achieved. So, I decided to live with the
name 'temp-rpool'. But, is renaming 'rpool' recommended or supported
parctice ?
Any help is appreciated.
Thanks
Arjun
