02-28-2012 10:46 PM  Open-iscsi /dev pollution I am setting up a
couple of machines to access an iscsi san (IBM) to host virtual
machines. I have open-iscsi, multipath, clvm, and gfs, which
seem to work ... sort of.  My problem is that the san has 2
controllers, and each controller has 2 ethernet ports
(redundancy). This results in 4 paths to the target. The target
has 7 luns, which means open-iscsi creates about 28 entries in
/dev. Multipath then creates a reasonable number of entries as
/dev/mapper/mpathx, but /dev is full of junk. Also, the devices
mapped to the inactive controller are filling my logs with
errors from multipath, and any access like vgscan or fdisk -l
fills the console with errors, and runs slowly, while it sorts
itself out.  Is it possible to tell open-iscsi that I just want
lun6 most of the time and manually ask for other luns in the
event that I need something off them?  As an aside, does anyone
know how force service start
