HBA enumeration and multipath configuration
...his host we have had varying combinations of the mapping of HBA to an enumerated /sys node. e.g.: host0 host2 host3 or host1 host3 host4 other combinations, etc. This messes up our multipath filtering for weightedpath priority settings.

dm-multipath do not autoscan partition table
...or accessing these disks I use dm-multipath, since I use 2 separate networks for access. For these reasons I want host system to force not to scan dm-multipath disks for partitions. According to multipath.conf man there should be feature to do it defaults { find_multipaths yes user_friendly_names no # features "1 no_partitions" } However when I try this error: Dec 8 21:45:40 vnode4 kernel: device-mapper: table: 253:41: multipath: Unrecognised multipath feature request Dec 8 21:45:40 vnode4 kernel: device-mapper: table: 253:41: multipath: Unrecognised multipath feature...

Multipath pools - practical for use?
Hi all, Writing up some Fedora documentation, and looking to figure out the best way of mapping multipath network(!) LUNs to pools in libvirt. ie Infiniband SRP LUNs, but would probably apply to Fibre Channel equally as well. There are two approaches I can think of easily: a) Large LUNs (ie TB+) that are mapped to a host server as disk, with each LUN being configured as an LVM

Device-mapper-multipath not working correctly with GNBD devices

dm-multipath use
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

SUMMARY : multipath using defaults rather than multipath.conf contents for some devices (?) - why ?
The reason for the behaviour observed below turned out to be that the device entry in /etc/multipath.conf was inadvertently appended *after* the devices section , rather than inside it - so that we had #devices { # device { # blah blah # } (file has a bunch of defaults commented out) # etc #} # # device { our settings } *rather

BUG(?): multipathd confusion leads to kernel panic in Xen 3.2.1-rc2
Hi all. While playing with iSCSI Enterprise Target + multipathd on CentOS 5.1 (both the target and the initiator/multipath/xen box are Cent 5.1), I encountered a strange fault condition that leads to a kernel panic in a version of Xen 3.2.1-rc2 pulled from a couple of days ago. My lab consists of two Clovertown machines with dual GigE into separate switches. The target box is softraid5

multipath using defaults rather than multipath.conf contents for some devices (?) - why ?
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
