nbd is a special network block device driver. Do not worry about it.

Again a hard reset. Were you exporting something on ocfs using the iscsi-target? Could you simplify this and take ocfs out for a minute. Just add some file or real disk or a virtual disk to the ietd.conf file for the lun. For example just stick: Lun 0 Type=nullio,Sectors=2097152 in the ietd.conf which will create a dummy lun. Then restart the target and log in from the other box and retry your reboot test with that (no ocfcs2 at all). Does that hang? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
