what's the fs type for mounting an existing Ubuntu partition?

Question

Trying to repair the usual broken Ubuntu I try chrooting following directions from this page However when I arrive to the mounting step where I need to mount the existing Extended broken Linux partition I can't because don't know the type and there are many. I tried ext, ext2, ext3, ext4 ... none work. the type is also not optional if I leave it empty I get mount: you must specify the filesystem type

What is the type of choice to mount an existing Linux 11.10 partition?

Answer 1

Assuming you set this up using more-or-less defaults, you should use the command:

mount -t ext4 /dev/sda4 /mnt

Note the -t ext4 part. Change /mnt to the mount point you decided upon.

Answer 2

blkid

All informations on attached drives and partitions needed for mounting can be read using the following command:

blkid

By this we will see the drive's device representation, its UUID and the file TYPE needed for mounting (or for entries in our fstab):

sudo mount -t TYPE /dev/sdXx /path/to/mountpoint
