Re: [Xen-API] [Xen-users] XCP Debian - ISCSI support?

First of all, let me say that I don't think that the iSCSI SR will work,
for other, unrelated reasons.

Second of all, I've found the reason for this particular failure: the
multipath tools are trying to call /sbin/pidof, when they should be
calling /bin/pidof. If you want to get past this error, but likely
encounter other, more sinister errors, edit the file
/usr/lib/xen-common/xapi/sm/mpath_dmp.py, line 46, and change
/sbin/pidof to /bin/pidof.

You may also have to do 'apt-get install multipath-tools' -- the
xcp-storage-managers package doesn't yet depend on it properly.

Third, let me reiterate that this probably won't work even with the fix,
so give this a try only if you're curious. We'll probably be disabling
all but a small number of known-to-work SRs very shortly.
