Recover Corrupt /dev

[Algis Zyle]

Checked that, Every other partition is at 50% or less filled...which is
what makes this so bizarre...and why it sounds like a "configuration"
file of sorts got corrupted....and Everything points to /dev items (even
the X error message says  "can't open /dev/xxxx"...for example in Rescue
mode....I made a back up with the default rescue /dev/st0 device....For
laughs I then tried to do a cpio using the Old Device
(/mnt/sysimage/dev/st0)....And it Worked !!!

If this is a server, I suspect that you probably have separate
partitions for /var /usr /home etc. You should check, especially
/var/spool, to see if they are also filled with garbage files. If you
have a /var partition that is filled X and many other programs and such
will not work.
