--vtzGhvizbBRQ85DL Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi Pawel, FreeBSD 5.3-BETA6 i386 I have a bunch of hopefully simple questions about gmirror(8). My /dev/mirror/m0 is a mirror of ad1 and ad3 providers, with the following file system layout: /dev/mirror/m0a / /dev/mirror/m0b swap /dev/mirror/m0f /usr /dev/mirror/m0e /var Yes, I use both root and swap in GEOM_MIRROR, yay! 1. When I try to "bsdlabel -B /dev/mirror/m0", I get: # bsdlabel -B /dev/mirror/m0 bsdlabel: Geom not found Hopefully, using "/dev/mirror/m0c" works. Any clue why this doesn't work? 2. Before a reboot, the state of the mirror was "COMPLETE". After a first reboot, everything was ok. After a second reboot, I got this: ad0: 38166MB <ST340014A/3.06> [77545/16/63] at ata0-master UDMA100 ad1: 38204MB <SAMSUNG SV0411N/UA100-11> [77622/16/63] at ata0-slave UDMA100 ad2: 38166MB <ST340014A/3.06> [77545/16/63] at ata1-master UDMA100 ad3: 38204MB <SAMSUNG SV0411N/UA100-11> [77622/16/63] at ata1-slave UDMA100 GEOM_MIRROR: Device m0 created (id=3D411263865). GEOM_MIRROR: Device m0: provider ad1 detected. GEOM_MIRROR: Device m0: provider ad3 detected. GEOM_MIRROR: Device m0: provider ad3 activated. GEOM_MIRROR: Device m0: provider mirror/m0 launched. GEOM_MIRROR: Device m0: rebuilding provider ad1. Any idea why it thinks ad1 should be rebuilt? 3. The syncing process takes very long, how do I tune it using the kern.geom.mirror sysctls? 4. Will the following work with GEOM_MIRROR? - mirror m0 is originally from two 10G providers (p1 and p2) - remove p2 from the mirror - add p3 of size 20G to the mirror - wait until p3 synchronizes with p1 - remove p1 from the mirror Will m0's size grow up to 20G after this procedure?
