[pve-devel] [PATCHv2] Add support for multipath-backed direct attached storage

Okay, there's problem: Linux is little ugly when it comes to delete 
external LUN.
So we have to unlink (rescan-scsi-bus.sh -r or echo 1 > 
/sys/block/sdX/device/delete) all paths to this LUN from all nodes, and 
only then we may safely delete it. BTW, iSCSI (not direct) storage is 
also affected (at  least if we have installed multipath-tools).

Is there easy way to run some code on all cluster nodes, wait it to 
complete and then continue?
