similar to: Adding handling for Multipath storage devices

All other patches from the sequence remain unchanged. Repost of patch 6 based on comments from Joey to follow. Mike

I am attempting to get multipath working with device-mapper (CentOS 4.2 and 4.3). It works on EVERY install of mine from RH (also v4.2, 4.3), but the same multipath.conf imported to all my installs of CentOS do not work. Note that I have tested a working 4.2 configuration file from RH on CentOS 4.2 and a working 4.3 configuration (it changed slightly) on CentOS 4.3. Neither worked. Our production

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 all We have a rh linux server connected to two HP SAN controllers, one an HSV200 (on the way out), the other an HSV400 (on the way in). (Via a Qlogic HBA). /etc/multipath.conf contains this : device { vendor "(COMPAQ|HP)" product "HSV1[01]1|HSV2[01]0|HSV300|HSV4[05]0" getuid_callout "/sbin/scsi_id -g -u -s /block/%n"

Hi, I have a host which is connected to SAN via single Fibre channel HBA (qlogic). I have several LUNS assigned to this (sdc, sdd). I added another single port HBA to this host. I can now see two world wide names. Now the confusion is which world wide name does sdc and sdd is/was using. scsi_id -g -u -s /block/sdc only gives wwid but I need the wwn for sdc and sdd. Thanks Paras.

This set of patches introduces support for multipath devices for storage. Comments and suggestions are appreciated. Mike

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

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

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

Hello list members, In CentOS-5.5 I'm trying to achieve static assignment of SCSI device names for a bunch of RAID-60 drives on a Supermicro motherboard. The "scsi_id" command identifies all drives ok. The board has one SATA controller and three SAS/SATA controllers ... standard on-board ICH-10 ATA channels, an on-board LSI SAS/SATA controller, and two add-on SAS/SATA

Hello, I am trying to find out a best practice for a specific scenario. First of all I would like to know what is the proper way to set up multipath, who should care about it the host or the guest. Right now I have a setup where I have one multipath which sets my host to boot from FC SAN. I have another multipathed LUN in the host which is essentially a dm which I attached to a guest, however

Hi, I want to share a partition of an external disk between 3 machines. It is located on a Sun StoreTek 3510 and bound (via multipathing) to all 3 machines. One machine (say mach1) is the node I used to create the filesystem and setup /etc/ocfs2/cluster.conf. I copied the file to the other 2 machines. All use the same /etc/multipath.conf[1], too. All start /etc/init.d/ocfs2 at boot, all are

Hi again! Need to add here, since I been investigating a bit further, that it seems to be possible to add an NPIV vhba to the guest, using vdsm hooks. I've seen the reference to "host device assignments", which Dan pointed me too, but I didn't really understand the meaning of it at that moment. It would be interesting to hear from someone that have been doing it, how it would

Hello everyone, I am trying to setup persistent LUNs and having problems. I've been following instructions I found on the web and they refer to editing /etc/scsi_id.config file and adding options=-g line there. After doing so, I should be able to run scsi_id -g -s /dev/sd* and get proper results. I've modified file /etc/scsi_id.config appropriately: [root at psrwjmsafs1 etc]# grep

Hi, i want to do load balancing of 2 ISP's Everything is set up OK but one of the ISP's is loaded on 100% while the other is utilised on 1 - 5% I've read about Julians patches but they stop at 2.6.14. Is anybody aware of similar patches for higher patchlevels. 2.6.14 is not suitable for my setup Thanks for reading :) -- С уважение, Владимир Витков http://www.netsecad.com
