I have Centos-6.2 on my system(P-4,1GB RAM, 80GB hdd).While working on my system I just face one problem my all folder get symbol of lock
so I go for open terminal but my terminal is also not opened.So I shut down my pc without proper way.After restart my system I got shell prompt.their is one message (Give root password or press Ctrl-d)
so I give my password I got root@system#rompt which is saying run fsck manually without -a -p
so I run this option and again restart my system.In single mode user Here on root prompt I just type fsck -t ext3 /dev/sda3 and press enter that time I got warning message that checking mounted filesystem may damage your filesystem but I ignor the warning and I start file checking and pressing Enter continously.
after some time I restart my computer and when I try to start in normal mode that time I got following error.
mount:/dev/sda3 already mounted or /sysroot busy
according to mtab,/dev/sda3 is already mounted on /syroot.
I know I myself created this problem by forcefully checking mounted filesystem but after this I try take another hard disk in that harddisk I have Ubuntu 12.04 LTS I start ubuntu in single user mode and here when I try to mount the centos root partition (i.e mount -t ext3 /dev/sda3 /media) in ubuntu that time I got message on prompt as follow
mount: mount point /mount does not exist
root@kiran-System-Name:/# mount -t ext3 /dev/sda3 /media
mount: wrong fs type, bad option, bad superblock on /dev/sda3,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
After this when I try to check file system by(fsck this is also not working)
Then after this I start my system in normal mode and when Idouble click on my centos root partition that time it is showing only lost+found folder in it no other folders are their so how can I take my system to its prevoius mode.
