IIRC, LVM was wonky when I tried to fix something similar to this. Assuming you only want the partitions on sda, sdb, sdc and the multipath devices, try: filter = [ "a|/dev/dm-*|", "a|/dev/sda[0-9]|", "a|/dev/sdb[0-9]|", "a|/ dev/sdc[0-9]|", "r|.*|" ] -- Dave On May 3, 2:45 pm, James Hammer wro

By offline, did you mean the disk was offline on the target side? if so, do you know what type of target you're using open-iscsi against? If that is iscsi enterprise target, you can edit the configure file / etc/ietd.conf on the target side properly and restart the target service by "/etc/init.d/is
