hi Kava, I'm using mirrors in my zpools on snv_77, and recently upgraded the disks. I first replaced one 200Gb disk with a 320Gb using # zpool replace -f soundandvision c2t1d0s0 and after less than an hour the data had finished re-silvering. Then the next day when I was able to reboot my system, I replaced the other <320Gb disk, did another in-place replacement: # zpool replace -f soundandvision c3t1d0s0 At that point, I was all set to export the pool, but realised that I didn't need to because zfs had picked up that the disks were larger - an extra ~100Gb just showed up. I don't know whether using a raidZ or raidZ2 pool requires the export/import routine, but I hope it doesn't. cheers, James C.
