In my case the disks were vastly different sizes so overwriting the vtoc didn't seem like a good idea. I has OS osol.11-109 on c3d1s0 but it was 25gb of a 60gb disk. The mirror I inserted was a 500gb disk. I skipped the overwrite part and basically did all the rest and on Casper D s' advice rebooted once more after detaching the old disk. attach step (mirror is showing 25gb like the base installgrub reboot Mirror still showing 25gb. detach step (mirror still showing 25gb) reboot Single disk now shows 500gb (well 449) rpool 449G 81K 449G 1% /rpool Now all is humpty dumpty with OS on the new 500gb disk. When the other 500gb comes that I ordered... I'll insert it and mirror up. I'll have mirrored redundancy of a nice hefty rpool. I'm not sure what would happen if I had overwritten the vtoc like you suggest. You might consider finding out and edit that case into your tutorial. I've about experimented myself into a dither already. Its already a nice tutorial though.. good work. _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
