------- Comment From [email protected] 2016-12-15 12:23 EDT------- An observation:
Having Cinder and Nova-compute on the same host, and using LVM and iSCSI backends might be causing some race conditions in multipath. The syslog is littered with messages like this: Nov 23 03:17:47 ub01 multipathd[179286]: io_setup failed Nov 23 03:17:47 ub01 multipathd[179286]: uevent trigger error Nov 23 03:17:47 ub01 systemd[188085]: dev-disk-by\x2dlabel-cloudimg\x2drootfs.device: Dev dev-disk-by\x2dlabel-cloudimg\x2drootfs.device appeared twice with different sysfs paths /sys/devices/platform/host16/session13/target16:0:0/16:0:0:1/block/sdav/sdav1 and /sys/devices/platform/host64/session61/target64:0:0/64:0:0:1/block/sdco/sdco1 Nov 23 03:17:47 ub01 systemd[1]: dev-disk-by\x2dlabel-cloudimg\x2drootfs.device: Dev dev-disk-by\x2dlabel-cloudimg\x2drootfs.device appeared twice with different sysfs paths /sys/devices/platform/host8/session5/target8:0:0/8:0:0:1/block/sdam/sdam1 and /sys/devices/platform/host64/session61/target64:0:0/64:0:0:1/block/sdco/sdco1 Nov 23 03:17:47 ub01 systemd[188085]: dev-disk-by\x2duuid-74722b08\x2d9998\x2d44e7\x2d8898\x2d5d5e96f303af.device: Dev dev-disk-by\x2duuid-74722b08\x2d9998\x2d44e7\x2d8898\x2d5d5e96f303af.device appeared twice with different sysfs paths /sys/devices/platform/host16/session13/target16:0:0/16:0:0:1/block/sdav/sdav1 and /sys/devices/platform/host64/session61/target64:0:0/64:0:0:1/block/sdco/sdco1 Nov 23 03:17:47 ub01 systemd[1]: dev-disk-by\x2duuid-74722b08\x2d9998\x2d44e7\x2d8898\x2d5d5e96f303af.device: Dev dev-disk-by\x2duuid-74722b08\x2d9998\x2d44e7\x2d8898\x2d5d5e96f303af.device appeared twice with different sysfs paths /sys/devices/platform/host8/session5/target8:0:0/8:0:0:1/block/sdam/sdam1 and /sys/devices/platform/host64/session61/target64:0:0/64:0:0:1/block/sdco/sdco1 No idea if this is the reason you're seeing the problem or not.. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1644785 Title: Ubuntu Openstack Mitaka can only deploy up to 52 instances To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1644785/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
