I recently upgraded our SXCE svn_72 box to OpenSolaris 2009.06 (snv_111b). It wants to me to upgrade my zpool to the latest version now.
We need to plan upfront for things like
zpool scrub because of the amount of time it takes and the IO intensive nature of the command. Our virtual machine disks on it grind to a halt.
Should I expect the same for
zpool upgrade? We have about 1.5TB spread across two raidz1's made up of 5 and 7 disks respectively.
