Re: replacing harddisks
I have gmirror of two 200GB disks where I have whole /usr f my freebsd 7.2 system. root, /var and /boot are on other disk, but I need to replace those both disks with bigger ones now. To get bigger /usr. So what I'm wondering now is if there is way to take one disk out of mirror (geom) and add bigger. yes. man gmirror gmirror remove , gmirror forget. So it would be one 200g and one 640g. And after sync replace other 200g with yes. make new (single disk at first) gmirror on new drive, copy data and make it bootable, shutdown, replace other 200G drive, boot from 640G and do gmirror insert ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

You don't need to add both new disks at the same time (you may not even have enough sata connectors) and you don't even have to leave both of the original mirror disks connected while copying the data. It will still work the same if the original array is degraded. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
