Yes, my russian is rusty :-). I have bitten the bullet and spend 3-4 days doing the migration. I wrote the details here: http://www.jcea.es/artic/solaris_zfs_split.htm The page is written in Spanish, but the terminal transcriptions should be useful for everybody. In the process, maybe somebody finds this interesting too: http://www.jcea.es/artic/zfs_flash01.htm Sorry, Spanish only too. > Overall, your plan seems okay and has more failsafes than we've had > - because longer downtimes were affordable ;) However, when doing > such low-level stuff, you should make sure that you have remote > access to your systems (ILOM, KVM, etc.; remotely-controlled PDUs > for externally enforced Yes, the migration I did had plenty of safety points (you can go back if something doesn't work) and, most of the time, the system was in a state able to survive accidental reboot. Downtime was minimal, less than an hour in total (several reboots to validate configurations before proceeding). I am quite pleased of the eventless migration, but I planned it quite carefully. Worried about hitting bugs in Solaris/ZFS, though. But it was very smooth. The machine is hosted remotely but yes, I have remote-KVM. I can't boot from remote media, but I have an OpenIndiana release in the SSD, with VirtualBox installed and the Solaris 10 Update 10 release ISO, just in case :-). The only "suspicious" thing is that I keep "swap" (32GB) and "dump" (4GB) in the "data" zpool, instead in "system". Seems to work OK. Crossing my fingers for the next Live Upgrade :-). I have read your message after I migrated, but it was very interesting. Thanks for taking the time to write it!.
