A few things, ask the customer to run the command 'multipath -v4'
as root after the package install failure so we can see what's going on.
There's at least one bug in the multipath.conf
1) scsi_id path is wrong
2) the blacklist regex is suspect
1)
Replace all calls to scsi id with:
"/lib/udev/scsi_id -g -u -d /dev/%n"
2) This regex assumes the sd names are ordered, this is never true.
Why are these sd devices being blacklisted to begin with?
blacklist {
devnode "^sda[1-7]"
devnode "^sd[f-z]"
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
devnode "^hd[a-z]"
}
SD driver pre-allocates up to 15 partitions per whole block device,
the first regex only filters out the 1/2 of the possible partitions of
the first probed device.
If I'm to believe this blacklist then we're looking to serve
sda8-15, sdb, c,d,e and that's it.
I don't think this blacklist is viable, try commenting out the first two
devnodes.
Please try each change independently and as a whole, and report.
