I've been trying to get a gmirror system disk running on a Dual Xeon supermicro server with 5.4 release. I followed Ralf S. Engelschall's how-to at: http:// people.freebsd.org/~rse/mirror/ Once the mirror was established and I rebooted the machine for the first time, I encountered a problem. It appears that the gmirror kernel module is not being loaded before the system tries to mount the partitions, and consequently, after falling back to a default mount of /dev/da0s1a for root, it fails to single user mode complaining that /dev/mirror/gm0s1X is not available. In single user mode, I can issue the command "gmirror load" which initializes the mirror device, but given that da0s1a is already in use, the mirror only includes device da1s1 When I exit to multiuser mode, the boot process completes, mounting all partitions according to /etc/fstab, with the exception of / which is still mounted from da0s1a I have the following entry in /boot/loader.conf: geom_mirror_load="YES" my /etc/fstab file is: # Device Mountpoint FStype Options Dump Pass# /dev/mirror/gm0s1b none swap sw 0 0 /dev/mirror/gm0s1a / ufs rw 1 1 /dev/mirror/gm0s1d /var ufs rw 2 2 /dev/mirror/gm0s1e /tmp ufs rw 2 2 /dev/mirror/gm0s1f /usr ufs rw 2 2 /dev/mirror/gm0s1g /var/spool ufs rw 2 2 the devices mounted after manually loading gmirror while in single user mode during the boot process are: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/da0s1a 253734 158970 74466 68% / devfs 1 1 0 100% /dev /dev/mirror/gm0s1d 1012974 33854 898084 4% /var /dev/mirror/gm0s1e 253678 12 233372 0% /tmp /dev/mirror/gm0s1f 2538478 1846726 488674 79% /usr /dev/mirror/gm0s1g 2502638 20 2302408 0% /var/spool /var/log/messages has these entries which show the problem with the drive being in use before gmirror attempts to include it: May 16 15:58:19 kernel: Mounting root from ufs:/dev/da0s1a May 16 15:58:19 kernel: GEOM_MIRROR: Device gm0 created (id=2862162848).

May 16 15:58:19 kernel: GEOM_MIRROR: Device gm0: provider mirror/gm0 launched. I've been bashing my head on this for a couple of days, but I can't seem to get to the bottom of this. I've tried adding the following entries in the kernel and recompiling: options GEOM_MIRROR options GEOM_LABEL but the problem persists. Am I missing something obvious? Any ideas? Any other information I should include above? Thanks, Lapo Nustrini Seanet Corporation lapo@seanet.com
