[Bug 368491] Re: Cannot mount partition on iSCSI LUN
This is not a bug, please close this ticket. When the multipath-tools package is installed, the device-mapper takes exclusive control of new disks - provided they are not blacklisted in multipath.conf. It does this so that it can create a "multipath" device node. This is so that when a disk is discovered with the same wwid it can be added under the "multipath" device node. For example, if the iscsi initiator logs in to a target and /dev/sdg is created, this will be taken by device-mapper which will then create a node under /dev/mapper/ corresponding to /dev/sdg. If the iscsi initiator logs into another target and /dev/sdh is created, and this has the same wwid as /dev/sdg, then device-mapper recognises that they are alternate paths to the same LUN and attaches /dev/sdh to the same node under /dev/mapper. So the solution is just to try and mount the node under /dev/mapper instead of the /dev/sd* node, if multipath-tools are installed. Sorry for the confusion - I didn't realise when I raised this bug that I had multipath-tools installed. Or even what multipath-tools was for!

Hi, Just out of interest... which virtualization server requires both open-iscsi and multipath-tools?

[Bug 368491] Re: Cannot mount partition on iSCSI LUN
Got it! There's a conflict between open-iscsi and multipath-tools. After removing multipath-tools, mounting iSCSI LUNs works fine! So there are two options: 1. quick fix: mark the conflict in the package meta-data so that they cannot be installed simultaneously 2. slow fix: work out why mounting iSCSI LUNs fails if multipath-tools are installed and fix it. Personally, I don't mind which..., I'm now happy.
