Hi,

I have a little problem with my 2nd HD :

At the first Ubuntu Boot. all work.
After... My 2nd HD (hdb) is umounted by it's in my fstab...

I have tested some commands :

My fstab

Quote:

# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda1 / ext3 defaults,errors=remount-ro 0 1
/dev/hdb1 /data ext3 defaults 0 2
/dev/hda5 none swap sw 0 0
/dev/hdc /media/cdrom0 udf,iso9660 ro,user,noauto 0 0
/dev/hdd /media/cdrom1 udf,iso9660 ro,user,noauto 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto 0 0

It is umounted :

Quote:

root@Ichigo:/home/ren # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda1 55G 9,7G 42G 19% /
tmpfs 506M 0 506M 0% /dev/shm
/dev 55G 9,7G 42G 19% /.dev
none 5,0M 2,8M 2,3M 56% /dev
/dev/hdc 1,2G 1,2G 0 100% /media/cdrom0

i mount it :

Quote:

root@Ichigo:/home/ren # mount /dev/hdb1 /data/
mount: /dev/hdb1 already mounted or /data/ busy

I use -f fonction now and it's ok by another problem begins :

Quote:

root@Ichigo:/home/ren # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda1 55G 9,7G 42G 19% /
tmpfs 506M 0 506M 0% /dev/shm
/dev 55G 9,7G 42G 19% /.dev
none 5,0M 2,8M 2,3M 56% /dev
/dev/hdc 1,2G 1,2G 0 100% /media/cdrom0
/dev/hdb1 55G 9,7G 42G 19% /data

its a 80Gb HD... not 55...

Ooook... there is obliviously some evil magic involved.

First, is there something in your log (dmesg)? This sound like a deeper problem than just a fstab, you better check a close look at your logfile, it sound like corrupted partition or something similar to me.

Also, instead of using "df -h" to find out if the drive is mounted, you should take a look to "/etc/mtab", if df -h can't read the drive, it is possible it just doesn't show it. Are you able to browse /data as this point? If you get some I/O error, then there is probably something very bad about it.

You might want to try fsck.ext3 over this drive (*BIG FAT WARNING* : Do this ONLY on the umounted drive and DON'T say yes to any filesystem modification fsck want to make) to make sure there isn't anything wrong with the fs.
