No more process /etc in this run level

any one know .. plz reply soon ... coz i 'm working as data center

Might be disk errors.does not look like superblock corrupt. Try fsck repair. Is this system part of a cluster config setup? What is your current run level? Pls provide output off run level and O//s version?

end -request: i/o error / dev hdb, sector 2566830

That should be your reason right there. You have a disk error on read. Time to get the backup tapes out and a new hard drive.

Also, this is a web forum. a "Plz reply soon" won't get you any expedited help. There is an emergency forum elsewhere, but I suggest if you have urgent needs, that you get a support contract in place.
