hi,all Recently,i read the source code of PG scrub.The ceph periodically shed_scrub if the system load is not too high. And adminstrator can manually scrub the specified OSD or PG using cmds. but many questions come along with me when i got thourgh . why did ceph need scrub? what scrub used for? because the OSD use three threads to handle the scrub transactions, maybe it has a great effect on the stablity or performance of ceph? thank you！ -- 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
