Re: Linux Mounting problem

[Jim Roland <jroland@roland.net>]

He is getting these errors because his /etc/rc.d/rc.sysinit is shuttling 
all output from the commands in the script to be written to /dev/null 
and his FS is mounted as read-only.  It never gets mounted as read-write 
because of fsck failing to approve the check with an OK status.  If 1-2 
boots in rescue mode (or as "linux single") don't fix the errors, the 
last step (e2fsck) should be run and should fix the error, unless there 
is serious drive corruption.

Jim Roland, RHCE
