10:06 a.m.
Good morning,
/var/log/messages is being filled with following message "multipathd: 104:0:
reinstated". I though it might be a bad controller card, or something wrong with the
hardware as suggested in IRC, but I have installed FC 22 64bit on two separate machines
(same configuration) and I’m getting these same message.
The messages don’t seem to be effecting performance or have any effect on data, and short
of being annoying, I want to make sure there is not some more serious/heinous issue going
on that I need to be aware of.
Machine Specs:
Proliant DL160 Smart Array E200 controller running RAID 1 (250GB mirrored).

Maybe the log will disappear if you include the raid device in the blacklist
section in the multipath configuration. Or (if you don't use SAN storage as
it seems) you can disable the multipathd daemon.

Have a question? Ask away: http://ask.fedoraproject.org
I would like to, but this is a root partition so when I do multipath -F it says device is
in use, I would also need to update fstab, to reflect the new locations of root, swap, and
boot. The question is this…. Can I do so without having to created a new initrd? or
reconfiguring grub?

Did you blacklisted the device in /etc/multipath.conf and reloaded the
service? If you did it, what is the output of multipath -ll command?
About /etc/fstab, I think you don't need update nothing, as the partitions
are identified by UUID not by device name.

So...I thoroughly am not getting multipath at all :(
Where is the UUID for /boot partition?? The one that is NOT associated with multipathd? I
want to setup fstab and disable the device in in multipathd.conf, but I’m afraid if I do
that right now the loader won’t be able to find the boot partition as it still points to
mpatha1. In fact, all references in grub.conf are to UUID
9abf4d-17aa-47fb-8f22-5d0d33711684 which is /dev/mapper/mpatha1
Am I missing something??

Ok, you can be sure the real device under /boot in /dev/disk/by-uuid/
I guess you will have 9abf4d-17aa-47fb-8f22-5d0d33711684 pointing to /dev/cciss/c0d0p1
If I'm right, I think you will not have problems at boot time...
