Operating Systems Solaris How to increase the size of rpool in Solaris 11? Post 303025269 by Peasant on Monday 29th of October 2018 11:29:03 PM

zpool detach is a destructive operation, so no you cannot reuse / boot that disk.

If you are using LDOM, you could just poweroff the ldom, and remove one out of two disks using ldm commands.
You should now have two identical bootable rpools.
Be sure to reconfigure your solaris instance when booted on another LDOM and remove degraded part of mirror from both operating systems.

Perhaps same can be achieved online, by using zpool offline <old disk>, followed by zpool detach <old disk> and from hypervisor ldm rm vdisk ..

You can test this using Solaris x86 and KVM, of course you will now not be using ldm commands, but create a new KVM solaris with disk you cloned with one of the techniques mentioned.
There is also an option of storage cloning techniques, just make sure those luns are never on the same LDOM.

As for links, login to My Oracle site and search for 'zpool split rpool'.

ZFS send/recv should be used to backup zfs filesystems, including rpools, while split would be second best and storage cloning as a last resort.
Everything else is hackery, do not try to reinvent the wheel.

Hope that helps.

Peasant.
