Hi,
Sorry, I got waylaid at the end of yesterday - catching up... (sorry for length of thread now as well, but would like to get to the bottom of this)
Have seen posts about ovirt-node... I personally like the idea and hope that it continues to develop. Having to load a Linux distro up and then put ovirt hypervisor on it is more work and then you need to worry about upgrading the linux distro and ovirt and suddenly ovirt doesn't run on the distro you have and you start over. IMHO anyway.
All of the LUN names are listed in /dev/mapper
/etc/multipath.conf is thus
# RHEV REVISION 1.0
defaults {
polling_interval 5
getuid_callout "/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/%n"
no_path_retry fail
user_friendly_names no
flush_on_last_del yes
fast_io_fail_tmo 5
dev_loss_tmo 30
max_fds 4096
}
devices {
device {
vendor "HITACHI"
product "DF.*"
getuid_callout "/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/%n"
}
device {
vendor "COMPELNT"
product "Compellent Vol"
no_path_retry fail
}
}
But on the multipath -ll round robin is enabled...
I can't see how the firmware missing can be a problem if all my disks are appearing on node. Some cards don't need to be flashed, they can be if needed but if my LUNs are appearing, then I assume it is working.
Sorry, I am very new to node and not much experience with FC under Linux, so trying to get up to speed on commands...
Which ovirt am Iusing? Not sure what you want back, uname -a yields 2.6.32-431.3.1.el6.x86_6
The iso I used is ovirt-node-iso-3.4-20140423.0.el6.iso from the releases/stable/iso folder - I am fairly sure, there are two ISOs there. Unfortunately I am not in the office today and can't get to the desktop where I burned the ISOs from...
Thanks
Bill

Ah, I mixed you an Bill up in the thread.

Well, we did some multipath changes lately. Let#s see what Bill says:
Bill,
what node are you using?
What does multipath -l say?
How does /dev/mapper/* and /dev/multipath.conf look like?
And is the disk appearing on Node and/or Engine?
Thanks!
