zpool replace mypool 1tbdevice 1.5tbdevice When all devices in a raidz are grown, the raidz grows automatically iirc (it does for mirrors at least). > Another example, would be that I have a pool with some older T3Bs and > newer SE3511.

Long time ago.. You can replace a single device with another device.. what you can't do at the moment is for example to replace a hwraid5 (single device) with a raidz (multiple devices) or replace 3 t3b's with a single se3511.. For that, you need the evacuate/shrink thingie which I've heard ETAs around years end. /Tomas -- Tomas Ögren, [EMAIL PROTECTED], http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Umeå `- Sysadmin at {cs,acc}.umu.se _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
