I am still troubleshooting the issue, I haven’t found any resolution to my issue at this point yet. I need to figure out by this Friday otherwise I need to look at Xen or another solution. iSCSI and oVIRT seems problematic.
The configuration of iSCSI-Multipathing via OVirt didn't work for me either. IIRC the underlying problem in my case was that I use totally isolated networks for each path. Workaround: to make round robin work you have to enable it by editing "/etc/multipath.conf". Just add the 3 lines for the round robin setting (see comment in the file) and additionally add the "# VDSM PRIVATE" comment to keep vdsmd from overwriting your settings. My multipath.conf:
# VDSM REVISION 1.3 # VDSM PRIVATE
defaults { polling_interval 5 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 # 3 lines added manually for multipathing: path_selector "round-robin 0" path_grouping_policy multibus failback immediate }
# Remove devices entries when overrides section is available. devices { device { # These settings overrides built-in devices settings. It does not apply # to devices without built-in settings (these use the settings in the # "defaults" section), or to devices defined in the "devices" section. # Note: This is not available yet on Fedora 21. For more info see # https://bugzilla.redhat.com/1253799 all_devs yes no_path_retry fail } }
To enable the settings: systemctl restart multipathd See if it works: multipath -ll HTH, Uwe
