Re: Moving to RAID1
Hi, I get this error now when trying to insert the disk # gmirror insert gm0 /dev/ad14 gmirror: Provider ad14 too small. found this error is being mentioned before on the mailing lists. hard disks are of the same size.couldn't find a solution for this one. Any way to fix this?

If you do it correct way you will not. It's possible if you make a mistake and do something like mirror the wrong way you would. Anyways to make sure in the procedure of setting up raid1 that i shouldn't have to go single user mode or change something at the boot prompt when rebooting after this is setup. Again if you do it incorrectly you may need to resort to these procedures. However if you follow the handbook accurately you should be fine. -- Adam Vande More ___ 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

One of the drives may be a few blocks smaller but thats enough. What I would do is slice up the smaller disk as you see fit. Create the mirror with only one disk/slice in it. newfs and mount the new mirror up Copy all the data from the bigger disk to the smaller one (rsync -aP /big/ /small/ would do the job nicely). Sanitize what you have done 8) umount the bigger disk slice up the same as the 1st disk add to the mirror (should add as its bigger) This is all assuming the filesystem(s) you are doing isnt the root fs. If it is you are going to have to make a trip with some kind of live cd/usb stick. If you are lucky you might be able to use any remote management card on the system eg dell drac. However whichever way you do it it will involve downtime 8( ___ 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

Re: Moving to RAID1
Hi: Using gmirror you wont loose any data, just be carefully editing fstab to point the right devices (triple check). Its actually quite easy. Anyway if you can get console access its better just for precaution.
