Hallo Heinz-Peter,

> Allerdings konnte ich keine Option zur Veränderung des LVM finden.

dem Mann soll geholfen werden. Folgende Notizen habe ich
mir diesbezüglich gemacht. Wie üblich ohne Gewähr ;-)

Logisches Volume vergrößern
---------------------------

1. VM anhalten
   xm shutdown eis1-test

2. Aktuelle Volumegröße auslesen
   lvs  -> 9.77G

3. Volume vergrößern indem man die neue Größe angibt
   # lvextend -v -L 30G /dev/vg/eis1-test
   Finding volume group vg
   Archiving volume group "vg" metadata (seqno 19).
   Extending logical volume eis1-test to 30.00 GB
   Creating volume group backup "/etc/lvm/backup/vg" (seqno 20).
   Found volume group "vg"
   Found volume group "vg"
   Loading vg-eis1--test table
   Suspending vg-eis1--test (254:5) without device flush
   Found volume group "vg"
   Resuming vg-eis1--test (254:5)
   Logical volume eis1-test successfully resized

4. Existierendes Dateisystem auf Fehler prüfen
   # e2fsck -f -v /dev/vg/eis1-test
   e2fsck 1.40.8 (13-Mar-2008)
   Pass 1: Checking inodes, blocks, and sizes
   Pass 2: Checking directory structure
   Pass 3: Checking directory connectivity
   Pass 4: Checking reference counts
   Pass 5: Checking group summary information

     211089 inodes used (32.87%)
      16275 non-contiguous inodes (7.7%)
            # of inodes with ind/dind/tind blocks: 83929/9/0
    2517647 blocks used (98.35%)
          0 bad blocks
          1 large file

     194392 regular files
      10376 directories
        564 character device files
       5279 block device files
          1 fifo
        409 links
        468 symbolic links (467 fast symbolic links)
          0 sockets
   --------
     211489 files

5. Dateisystem vergrößern
   # resize2fs /dev/vg/eis1-test
   resize2fs 1.40.8 (13-Mar-2008)
   Resizing the filesystem on /dev/vg/eis1-test to 7864320 (4k) blocks.
   The filesystem on /dev/vg/eis1-test is now 7864320 blocks long.
