The following patches introduce support for multipath and cciss devices to the ovirt-node and node-image. Comments are appreciated. These patches assume that the 3 patches (2 node, 1 node-image) from Joey are all incorporated. Mike

Hi list! I have a server with dual port Qlogic iSCSI HBA. I set up the same LUN for both ports, and boot the CentOS installer with "linux mpath". Installer detects multipathing fine, and creates mpath0 device for root disk. Installation goes fine, and the system boots up and works fine after the install from the multipath root device. After install the setup is like this: LUN 0 on

glob(3) on HP/UX 11 always strips a trailing slash from a pathname. This breaks the differing semantics of rsync directory host:/foo/bar rsync directory host:/foo/bar/ Here's a patch which, at least, doesn't seem to do any harm on Solaris or Linux and fixes the problem on HP.

Anyone using it? I''ve tried but after about 5 min I always get kernel panic. My setup is based on nano.txt. I works well but only if CONFIG_IP_ROUTE_MULTIPATH_CACHED=n. I just wanted to play with the new mpath feature of ip. But enabling CONFIG_IP_ROUTE_MULTIPATH_CACHED always resuts in kernel panic. I''m not using any kernel patches from http://www.ssi.bg/~ja/ - are they needed

I'm seeing some strange behavior from OCFS2 while trying to mount mpath/dm-multipath devices under RHEL5. Sometimes I can mount the EMC-connected, dual-pathed volumes just fine and sometimes I get "device busy" errors. I've tried mounting by label and also by explicit /dev/mapper/mpathXpY name with the same unpredictable behavior. I've also noticed that sometimes when a

Hi, I'm using libvirt 0.8.3 on Fedora 14 (as I wrote earlier, I'm having some trouble updating to the newest version), and I'm having problems getting iscsi and mpath storage pools to work in a usable and consistent manner. I have two storage pools defined on the host machine, one for raw iscsi- devices and one for those same iscsi devices device-mapped by multipath. They look

I have several CentOS 6 boxes that mount iscsi based luns and use mpath. They all had problems shutting down as a result of unused maps not getting flushed as the system halted. After examining the init scripts, netfs, iscsi and multipathd all had the correct order but mpath failed to flush these maps and the system waited indefinitely. In the meantime I hacked this by adding a `/sbin/multipath

Hi all :) there is somekind of strange Routing problem that im getting with Linux-2.6.16 and iproute 2.6.16 , when i use command like : ip route add default nexthop via 1.1.1.1 dev eth0 nexthop via 1.1.1.2 dev eth1 all packets goes on 1.1.1.2 ( always last interface ) , whats is the problem ? this situation also tested with equalize flag , on two physical interface and etc ... -- Lady Luck

Hi! Report from my multipath tests today. My test virtual machine, that runs from an NPIV pool, is not able to use multipath. When I pulled the cable from one of the targets, it crashed. But, strangely, it could boot up again on that other path, that it just crashed on. That tells me it can use both paths, and is not limited to one of them only, but because the multipath layer isn't

I looked around but could not find any info on how to expand a libvirt managed LVM storage pool. I do not see any virsh command to do it but I was successful using the vgexpand command to add some more storage once I destroyed the pools and then restarted it. I'd like to verify that this is the proper way to grow the storage in a libvirt LVM storage pool. And this brings up a second

Are folks in the Centos community succesfully using device-mapper-multipath? I am looking to deploy it for error handling on our iSCSI setup but there seems to be little traffic about this package on the Centos forums, as far as I can tell, and there seems to be a number of small issues based on my reading the dm-multipath developer lists and related resources. -geoff Geoff Galitz Blankenheim

Hi, John, and thank you! This was a very thorough and welcome response, I was wondering where all the storage guys were... I will get back to you with more details later, specifically about multipath, since this needs to be investigated thoroughly. I have, with trial and error method, during the elapsed time, been able to attach the NPIV pool LUN to a virtio-scsi controller, and it seems it
