You could also use iSCSI. On your client you'll get SCSI-device-nodes |
| 6 |
(/dev/sdx) which you can use as PVs. It's very fast and reliable. |

My experience too :( |
| 11 |
After reconnecting to the iSCSI-target I have to |
| 12 |
|
| 13 |
# vgchange -a n vg-iscsi |
| 14 |
# vgchange -a y vg-iscsi |
| 15 |
|
| 16 |
to get my devices in /dev/vg-iscsi/* to work again (during disconnection |
| 17 |
they keep existing, but are not usable with misleading error messages). |
| 18 |
|

When using iSCSI-devices you should use /dev/disk/by-path/<taget-id> and |
| 20 |
not /dev/sdx, as these device names can change. |
