You are right - just removed and then re-inserted a component in one of the mirrors and the mirror synchronized fine in multi-user mode. -- Janos Dohanics ___ 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: FreeBSD 9, GPT and gmirror
I can't speak to the mirror issue, but I had difficulty trying to tweak the defaults in the install on a 128G SSD: When manually configuring the SSD, I tried to leave some extra space at the end of the SSD. Not sure that is necessary or not. In any case, I had a 128GB SSD, reported as 119GB. Auto config laid it out as ada1 119GB ada1p1 64KB freebsd-boot ada1p2 115GB freebsd-ufs / ada1p34GB freebsd-swap I then deleted the last 2 and re-created as 100GB and 4GB, at which point it showed ada1 119GB ada1p1 64KB freebsd-boot ada1p2 100GB freebsd-ufs / ada1p3 -15GB freebsd-swap (I may have the -15 wrong; main point is it was negative) After deleting and recreating in different order I managed to get it to ada1 119GB ada1p1 64KB freebsd-boot ada1p34GB freebsd-swap ada1p2 100GB freebsd-ufs / but when I tried to commit it, I got the error: Error mounting partition /mnt: mount: /dev/ada1p2: Operation not permitted The only way I could get it to actually write the distribution was to use auto and keep what it came up with. Is this problem specific to SSDs (seems unlikely)? Is there some magic sequence needed to tweak the Auto result to get it to work?
