Jeste bych se vratil ke gmirroru i kdyz je to mozna problem neceho jineho.
V noci "zmizel" jeden disk ze systemu:
Jul  9 22:22:48 track kernel: ad8: FAILURE - device detached
Jul  9 22:22:48 track kernel: subdisk8: detached
Jul  9 22:22:48 track kernel: ad8: detached
Jul  9 22:22:48 track kernel: GEOM_MIRROR: Device gm0: provider ad8 
disconnected.

# gmirror status
       Name    Status  Components
mirror/gm0  DEGRADED  ad4

kousek z /var/run/dmesg.boot
ad4: 238475MB <Seagate ST3250820AS 3.AAC> at ata2-master SATA150

Zkratka jako by ho nekdo ze serveru odpojil a me by ted zajimalo, jestli 
"se tohle u gmirroru stava" a mam treba zkusit reboot, nebo je to neco, 
co by se rozhodne stat nemelo a mam rovnou vyrazit do serverovny? Jeste 
se mi nestalo, ze by mi za chodu z niceho nic zmizel disk ze systemu. 
System zatim normalne bezi, ale obavam se, ze by treba po rebootu uz 
nemusel nabehnout vubec.
