[linux-lvm] File System type on (LVM) partition

[linux-lvm] File System type on (LVM) partition

[Julien Baboud]

hi,

 the different answers of my previously sent question had nothing to to
with what i expected,
 so i do it once again :

 is there a way to know the file system type installed on a partition
(wich could be of LVM type or not)
 tanx for your help.

 julien,
 4 Atix.

Either run 'mount', as suggested, or do 

  # file -sL /dev/hda1

You completely missed our point. LVM is *not* a filesystem. It is a layer
you can put on top of physical storage, and on top of LVM you can create
logical volumes which contain filesystems.

Now if your real question is: how can you check if a block device (ie
a storage device) contains a PV (Physical Volume, the lowest layer in
a LVM setup) I suspect there is some magic value on the disk you could
check for.

Someone should probably write some file(1) magic for it :)

I believe the stand ext2 is 83 and lvm is 8e so one
could check for those values

That's a really poor check. 83 is `Linux Native', which isn't limited
to ext2 at all. My LVM PV happens to be type 83 as well actually.
