There is no way to resize a gmirror provider without creating a new one. You could possibly insert the new large drive into the mirror, deactivate it, make a new gmirror on it (clobbering the old one), THEN use growfs.. but that's a lot mor ecomplicated and error-prone than doing it the right way using dump/restore. If downtime is a concern then use Ivan's method below but without going into single-user--just be sure to give -L to dump. > On Mon, 2008-08-25 at 14:37 +0200, Wojciech Puchar wrote: > > >> Hi! > > >> > > >> My situation: I have a server with FBSD 7 installed with two 40 GB > > >> disks in RAID 1 (gmirror) config. > > >> Now I have noticed the lack of space on the drive so I am thinking > > >> to change these disks for two 160 GB. > > >> What is the best way to clone the main hard disk in raid 1 config? > > >> Is > > > > gmirror remove yourmirrorname /dev/oneofdisk > > > > shutdown and replace this one with 160GB > > > > boot single user > > > > make gmirror with this new 160GB drive (only one drive now so not > > real mirror) > > > > newfs and copy all data make it bootable, shutdown, remove second > > 40GB drive, add second 160GB drive, boot and then > > > > gmirror insert yournewmirror seconddrive > > > > that's all. > > _______________________________________________ > > freebsd-questions@freebsd.org mailing list > > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > > To unsubscribe, send any mail to > > "freebsd-questions-unsubscribe@freebsd.org"
