Hello, This is the second time I experienced this so I thought and post to get some perspective. When this first happened, I suspected the kernel, and upgraded from 3.18.22 to 3.18.23. Scenario: - lab scenario - single osd host — osdhost01. Supermicro X8DTE-F - 2x X5570 + 48G RAM + 20x 4TB OSD + SSD journals — 5:1 osd:journal ratio. All OSDs stable, no active rebuilds / scrubbing, etc. - osdhost01 also runs a mon - Separate mon-only node — two monitors in cluster. - osdhost01 maps rbds, exports via NFS. - rbds = xfs formatted. - osds = btrfs formatted. - ceph 0.94.5 - calltrace only on NFS use. I haven’t observed a specific trigger IO pattern. - When OSDs exported via block methods — e.g. SCST, things are stable. Relevant / recent log entires — nothing significant preceding the below: - system returned back to normal after a reboot. — Nov 9 06:56:11 osdhost01 bash: 2015-11-09 06:56:11.209312 7f60a6669700 -1
