"Status: This code is now being ported to the upstream linux kernel reservation API added in this commit:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/block/ioctl.c?id=bbd3e064362e5057cc4799ba2e4d68c7593e490b When this is completed, LIO will call into the iblock backend which will then call rbd's pr_ops." Does anyone know how up to date this page? http://tracker.ceph.com/projects/ceph/wiki/Clustered_SCSI_target_using_RBD Is currently only Suse supporting active/active multipath for RBD over iSCSI? https://www.susecon.com/doc/2015/sessions/TUT16512.pdf I'm trying to configure active/passive iSCSI gateway on OSD nodes serving RBD image. Clustering is done using pacemaker/corosync. Does anyone have a similar working setup? Anything I should be aware of?
