unable to view contents of /home
 

contents of my home directory could not viewed. when i try to mount /home message comes: /home busy or mounted already.

when umount is tried the message: not mounted
my /home directory is on separate partition on the hard disk(/dev/sb1)
contents of /etc/fstab are:
/dev/sda1 / reiserfs acl,user_xattr 1 1
#/dev/sdb1 /home reiserfs acl,user_xattr 1 1
/dev/sda2 swap swap pri=42 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
sysfs /sys sysfs noauto 0 0
/dev/cdrom /media/cdrom subfs fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0
/dev/fd0 /media/floppy subfs fs=floppyfss,procuid,nodev,nosuid,sync 0 0




Morever when i removed the comment in line 2, there was no change.
pl help me out!

can you put the output of 'mount' here as well as the output of 'fdisk -l' please.

I crashed a hard drive recently
 

and the results were not great. i hope you have better luck than me.

based on my experience i would ask

1. if you have you reviewed the ouput of dmesg?

2 what is the output of:

fdisk -l /dev/dev/sdb1

3. what is the output of sbin/dumpe2fs /de/sdb1 (this will tell you lots of info including the location of superblocks)

if you see problems, you are probably going to need to read up on fsck and use one of the backup superblocks something like (assuming your backup superblock is 8193):

fsck -b 8193 /dev/sdb1

out put of mount:

/dev/sda1 on / type reiserfs (rw,acl,user_xattr)
proc on /proc type proc (rw)
tmpfs on /dev/shm type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/hda on /media/cdrom type subfs (ro,nosuid,nodev,fs=cdfss,procuid,iocharset=utf8)
/dev/fd0 on /media/floppy type subfs (rw,nosuid,nodev,sync,fs=floppyfss,procuid)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
usbfs on /proc/bus/usb type usbfs (rw)


output of 'fdisk -l':
