LINUX Server not starting up. xfs filesystem problem?
 

i have an HP proliant server n i am new to linux
the problem i am facing is that when i start the system it turns ON normally but after the linux starting up options like when we select whether to start it normally or in failsafe mode
after selecting one option out of the two
it comes up with following messages on the screen and get stuck over there.

[messages]

It looks like your XFS filesystem is corrupted. You can try fsck.xfs. I've never used XFS so I can't help you any further.

I sure hope you have a backup of this system... It looks like you may have to do a bare metal restore if the advice from Meson doesn't help.

no i dont have any backup of this system :(
@Meson
how can i get to a prompt to write this fsck command??

this is the screen i get after selecting the normal or failsafe mode for linux
please see if u can make out something from it.

It looks like it ran an fsck on it for you... I don't know what the stuff is about not being able to find the log head. I suggest you rename this thread, or start a new one, with "XFS: failed to find log head" in the title.
