I have noticed that sometimes it takes a lot of time for an OSD to go back up and in. From what i can see in the logs it is stuck on load_pgs for a while: 2014-08-21 15:32:04.711048 7fba11569780 0 osd.1 139 load_pgs 2014-08-21 15:32:04.712512 7fba11569780 10 osd.1 139 load_pgs 3.165_TEMP clearing temp 2014-08-21 15:32:19.648610 7fba11569780 10 osd.1 139 load_pgs 3.13b_TEMP clearing temp 2014-08-21 15:32:34.674773 7fba11569780 10 osd.1 139 load_pgs 3.36b_TEMP clearing temp It happens when you restart an OSD while there was an ongoing recovery in the cluster. The process isn't neither IO nor CPU heavy at that time, and judging by strace output it mostly does futex calls and a little IO on PGs. I am using Ceph 0.80.5. Have anybody noticed this behavior? Isn't it possible to clear temp faster? -- Pozdrawiam Michał Szymański -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
