Hej SSLUG-eksperter

Jeg har en ubuntu server kørende som selv har mounted sit filsystem
til at være ro.
Jeg har pasted output af dmesg herunder. Det jeg får ud af
nedenstående er at ext3 filsystemet har fejl.

Spørgsmålet er hvad jeg kan gøre ved det.  Jeg ville gerne køre en
fsck på partitionen men den er jo mounted og os sidder på denne
partition så jeg kan ikke umount'e den.

 Kan jeg reboote den og så køre fsck under opstarten eller er det for
risikabelt ?

mvh
Gunner
