questions about migration from ZEVO
Posted: Thu Dec 17, 2015 2:53 pm
I have two pools created by ZEVO. One serves as primary storage and the other as an offsite backup where I send/recv data every night. I'm looking to move from ZEVO to O3X. Questions (I'm sorry if that has been covered before, but I did search the forum before posting. Honest.):
1. If I replace ZEVO with O3X on one machine only, will the send/recv still work between the machines?
2. Do I need to rebuild my pool to get access to ZVOL features? Or, can I just upgrade the existing pool without moving the data around?
3. Would there be any performance (speed) benefits if I rebuild the pool from scratch. (I vaguely recall someone recommending to rebuild pools when moving to O3X, but that was at least 2 years ago.)
4. A very noob question: if I allocate a 1tb ZVOL on a 5 tb pool, does it mean that the available pool space is now 4tb even if the zvol is empty? This in contrast to zfs filesystem, which shares the available space among all filesystems on the pool (unless otherwise specified, of course)
Thank you for your help!
