I don't think there's anything vdsm should do right now. Once multipath provides these options as requested in bug 672575, the issue would disappear. Unless, of course, there is some functional effect to this temporary error message, I'll use this bug as a tracker for the multipath bug. Required underlying feature is being backported so no need for this bug. |
Description of problem: multipath (device-mapper-multipath-0.4.7-42.el5) on RHEL5 doesn't seem to support the following flags (672575): fast_io_fail_tmo dev_loss_tmo and when initiating multipath -l, i get the following error: mulipath.conf line 19, invalid keyword: fast_io_fail_tmo mulipath.conf line 20, invalid keyword: dev_loss_tmo please reconfigure multipath and remove those entries till multipath will back-port the fix.
