Subject: Update FAI partition handling for lvm disks.
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=227264a21dda2e45abeab635fbe16bce64d65ee3;p=gosa.git

Update FAI partition handling for lvm disks.
- Do not allow to add partitions to 'FAIlvmDevice' which are part of the currently edited disk. (Loop)
- Updated listing of lvm partitions.
- Save cn, instead of 'disk' + 'PartitionNr', e.g. lvm1.
- Fixed some loading errors for lvm devices.
