Hi Cephers, Using Ceph 0.94.9-1trusty we noticed severe I/O stalling during deep scrubbing (vanilla parameters used in regards to scrubbing). I'm aware this has been discussed before, but I'd like to share the parameters we're going to evaluate:
* osd_scrub_begin_hour 1 * osd_scrub_end_hour 7 * osd_scrub_min_interval 259200 * osd_scrub_max_interval 1814400 * osd_scrub_chunk_max 5 * osd_scrub_sleep .1 * osd_deep_scrub_interval 1814400 * osd_deep_scrub_stride 1048576 Anyway, thoughts on the matter or specific parameter advice is more than welcome. Cheers, Kees
