We have a freebsd 3.2 system and had to reboot it. Afterwards it could
not fine the following:
swapon: /dev/da0s1b: No such file or directory
swapon: /dev/da2s1b: No such file or directory
Automatic reboot in progress...
Can't stat /dev/da0s1a: No such file or directory
Can't stat /dev/da0s1a: No such file or directory
/dev/da0s1a: CAN'T CHECK FILE SYSTEM.
/dev/da0s1a: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
it seems that the above devices disappeared in /dev (See fstab file
below)and goes into maintenance mode.
_How do I recover the devices from my fstab file?? Why would they
suddenly disappear if there was no disk failure??
_There is no scsi errors and did a disklabel to check partitions and
everything looks good (see below):
