Could not mount Fedora

[seshomaru samma]

Hi there
I need to fix some files on my Fedora Linux. I run Knoppix and everything seemed great , I have Fedora running dual boot with XP and Knoppix mounted all the partitions succesfuly ,except the one I need -hda7 ( Fedora) . When I click on it I get an error:

Could not mount device
mount: I could not determine the file system type, and none was specified
What can I do?

what filesystem type is hda7 (ext2, ext3, reiserfs, etc)?

what does /etc/fstab report?

if knoppix is detecting it incorrectly (unlikley in my experience) you could try editing fstab to change the file system type.

when i run cfdisk from knoppix i get :

hda 7 Logical Linux LVM 27554.69

is LVM mounted in a different way than say ext3?

LVM (Logical Volume Management) is a storage method not a filesystem type. Your fedora filesystem resides inside this logical volume.

Does knoppix support LVMs?

I found out how to mount it, using this guide : http://www.knoppix.net/wiki/LVM2
But I cannot change the permissions- its still read-only.
Does anyone know how to do it?

Good catch on this issue.

By default, knoppix mounts any external filesystem read only. You may just have to remount the file system read/write (or explicity mount it rw).

after mounting manually, if you want to remount as read / write from the command line, you could run (as root)

mount -o remount,rw,dev /dev/hda7

should work.
