Hi, I was hoping somebody would be able to help with an issue that has me stumped. Sorry if this has been asked before but I haven't found a similar issue. I have Corosync+Pacemaker serving up an iSCSI target, using ocf::heartbeat:iSCSITarget and ocf::heartbeat:iSCSILogicalUnit. The backstore is an iblock of an LVM LV stored in DRBD on a local drive partition. /dev/sda3 - DRBD physical partition /dev/drbd0 - LVM PV /dev/VG0/iscsi1 - LVM LV iblock for iSCSI Every time that the target is removed and restored the WWID as seen by the initiators changes (fetched with "/lib/udev/scsi_id -g -u -d /dev/sdc"). I have multiple network routes so this changing of WWID seriously upsets multipath. For example, WWID is currently 36001405caa429dc7e474943bc6026541. Previously it was 360014057b86b6a48432485fb4201da9d Any pointers on how to make the WWID static? Target servers and initiators are running Debian stable with backport kernels. linux-image-3.16.0-0.bpo.4-amd64 3.16.7-ckt2-1~bpo70+1 targetcli 2.0rc1-2 lio-utils 3.1+git2.fd0b34fd-2 python-rtslib 2.1-2 Frustratingly I have access to an almost identical setup where the WWID is static. The only difference I can spot is that DRBD is on a separate drive without a partition table.
