I must have done soemthign wrong because i get errors.

All i did was run the script by typing

Code:

create_lvm.sh /dev/hda3 /dev/hdb1

(this seemed successful)

Then i followed it up with

Code:

umount /myth

When i typed that i got this error.

Code:

umount: /myth: not mounted

Then i followedi t up with this.

Code:

mke2fs -j -O sparse_super -m0 -i8000000 -L myth /dev/vg/myth

i get this error back.

Code:

Could not stat /dev/vg/myth --- JNo such file or directory.
The device apparently does not exist; did you specify it correctly?

Any ideas where i went wrong?

That one is harmless.

Try restarting the lvm stuff, and looking at the log file /var/log/messages

Oops... Sorry I was in a rush earlier. I meant something more like this:

Code:

umount /dev/vg/myth
/etc/init.d/lvm stop
/etc/init.d/lvm start

OBTW - Time for some full on debugging. What does the "mount" command show? Also we just want the tail end of /var/log/messages with any lvm related activity when you do that.
