The kernel dmesg for Instance {{bbfd7458-6dd6-4412-a8ba-8d417c3df56b}} has started reporting thousands of block I/O errors and these are starting to trickle up as a filesystem I/O errors. I suspect this is likely a hypervisor I/O issue. {code} [687301.556430] Buffer I/O error on device dm-3, logical block 3768490 [687301.556433] Buffer I/O error on device dm-3, logical block 3768491 [687301.556436] Buffer I/O error on device dm-3, logical block 3768492 {code} {code} $ openstack server show bbfd7458-6dd6-4412-a8ba-8d417c3df56b +--------------------------------------+-----------------------------------------------------------------------+ | Field | Value | +--------------------------------------+-----------------------------------------------------------------------+ | OS-DCF:diskConfig | MANUAL | | OS-EXT-AZ:availability_zone | nova | | OS-EXT-STS:power_state | 1 | | OS-EXT-STS:task_state | None | | OS-EXT-STS:vm_state | active | | OS-SRV-USG:launched_at | 2016-02-11T23:36:25.000000 | | OS-SRV-USG:terminated_at | None | | accessIPv4 | | | accessIPv6 | | | addresses | LSST-net=172.16.1.115, 141.142.209.121 | | config_drive | | | created | 2016-02-11T23:36:12Z | | flavor | m1.xlarge (5) | | hostId | f7fbf308022d02f52e1111c91cf578d852784d290d0e0ddb0d69635c | | id | bbfd7458-6dd6-4412-a8ba-8d417c3df56b | | image | centos-7-docker-20151116230205 (59a2a478-11ab-41c5-affc-29706d38d65a) | | key_name | vagrant-generated-comshorc | | name | el7-docker-jhoblitt | | os-extended-volumes:volumes_attached | [] | | progress | 0 | | project_id | 8c1ba1e0b84d486fbe7a665c30030113 | | properties | | | security_groups | [{'name': 'default'}, {'name': 'remote SSH'}] | | status | ACTIVE | | updated | 2016-02-11T23:36:25Z | | user_id | 83bf259d1f0c4f458e03f9002f9b4008 | +--------------------------------------+-----------------------------------------------------------------------+ {code}
