I had a motherboard start to throw hardware errors, so I pulled the disk
with FC6 loaded and did away with the computer. I have installed the disk
in a USB drive enclosure and am trying to mount it as a usb drive to pull
the data off onto a new computer. I get the following error when mounting
it:
$ sudo mount -t ext3 /dev/sdb2 /media/other
mount: wrong fs type, bad option, bad superblock on /dev/sdb2,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
$ dmesg | tail
sdb: sdb1 sdb2
sd 5:0:0:0: Attached scsi disk sdb
sd 5:0:0:0: Attached scsi generic sg2 type 0
kjournald starting. Commit interval 5 seconds
EXT3 FS on sdb1, internal journal
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Can't find ext3 filesystem on dev sdb2.
VFS: Can't find ext3 filesystem on dev sdb2.
$ sudo fdisk -l -u /dev/sdb
Disk /dev/sdb: 40.0 GB, 40007761920 bytes
255 heads, 63 sectors/track, 4864 cylinders, total 78140160 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 * 63 208844 104391 83 Linux
/dev/sdb2 208845 78140159 38965657+ 8e Linux LVM
hald can automatically assisted in mounting /dev/sdb1 (/boot).
I could use some help in understanding how to get the drive mounted since
it was originally an lvm2 volume with ext3 filesystem laid on top of it.
Thanks in advance.
