Subject: file system is not mounting
Question
QUESTION: Hi nix,
Hope you are doing well,
Nix, I have installed (perl-5,XFree86) Patches on Redhat-EL4 AS, i Don't find any errors while installing the patches, when i tried to reboot the server the filesystem is not mounting properly
Pls guide me how to mount a file system in single user mode and how to trouble-shoot this issue.
Thanks in Advance.
Thanks & Regards,
Bharath.
ANSWER: Hi.
Installation of patches should have nothing to do with proper FS mount. It would be helpful to know what the error message on the screen is. Does the system even start to boot?
You should be able to boot from the system/installation/rescue CD/DVD and let the utility try to diagnose the problem.

QUESTION: Hi nix,
The problem got resolved by using installation disk.
My question is while rebooting a linux server suppose if the filesystem doesn't come up,how to mount a filesystem manually in single user mode.
Thanks in advance
Thanks&Regards,
Bharath
Answer
Hi.
I would first take a look in /etc/fstab to see if there is a definition of the mount and if it exists try to mount it:
# mount /usr
If the mount is not defined, then you have to resort to manual mount, like this (if it is a Ext3 FS on a software RAID):
# mount -t ext3 /dev/md1 /usr
See "man mount" for a list of options. Each file system type has a ton of options, some of which deal with damaged or problematic file system instances.
