I made a RAID-1 setup with gmirror. It's 2 120-GB SATA disks.
The array seems to be breaking a lot. From dmesg:subdisk6: detached
ad6: detached
GEOM_MIRROR: Device gm0: provider ad6 disconnected.
ad6: 114473MB <Seagate ST3120827AS 3.42> at ata3-master SATA150
GEOM_MIRROR: Device gm0: rebuilding provider ad6I've noticed that after it finishes rebuilding the array, when I reboot, the last thing it prints to the monitor is something about "array destroyed." -- it seems to happen every time the system is rebooted.$ gmirror status
Name Status Components

Had exactly the same problem in i386, after each reboot or shutdown. For now - didn't found a solution too.

Oh - upgraded from 7.0 to 7.1 without any errors during the upgrade, the mirror was set on a 7.0 system if this maybe helps.

It sounds like a problem with the disk. You might run the tools against the disk provided by the manufacturer. You might also check the cables to make sure they are snug or just replace them.

Did this and there were no problems reported. Very weird :(

The hard drives check out OK with Seagate's tools. All cables OK.

Try to swap (or replace ad6 if you have another one) 1) disk and 2) cable and 3) power cable or connect disk as ad5 & ad7.

Known problem... What do you do inside of the gm0? Maybe Geli encryption (had the same problem when encrypting all slices within gm0, only)? Have a look at kern/113957 (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/113957) Problem is not really solved yet. :(
