You could also use iSCSI. On your client you'll get SCSI-device-nodes
(/dev/sdx) which you can use as PVs. It's very fast and reliable.

My experience too :(
After reconnecting to the iSCSI-target I have to

# vgchange -a n vg-iscsi
# vgchange -a y vg-iscsi

to get my devices in /dev/vg-iscsi/* to work again (during disconnection
they keep existing, but are not usable with misleading error messages).

When using iSCSI-devices you should use /dev/disk/by-path/<taget-id> and
not /dev/sdx, as these device names can change.

Bye,
Daniel
