Some scrub errors showed up on our cluster last week. We had some issues with host stability a couple weeks ago; my guess is that errors were introduced at that point and a recent background scrub detected them. I was able to clear most of them via "ceph pg repair", but several remain. Based on some other posts, I'm guessing that they won't repair because it is the primary copy that has the error. All of our pools are set to size 3 so there _ought_ to be a way to verify and restore the correct data, right?
Below is some log output about one of the problem PG's. Can anyone suggest a way to fix the inconsistencies? 2013-05-20 10:07:54.529582 osd.13 10.20.192.111:6818/20919 3451 : [ERR] 19.1b osd.13: soid 507ada1b/rb.0.6989.2ae8944a.00000000005b/5//19 digest 4289025870 != known digest 4190506501 2013-05-20 10:07:54.529585 osd.13 10.20.192.111:6818/20919 3452 : [ERR] 19.1b osd.22: soid 507ada1b/rb.0.6989.2ae8944a.00000000005b/5//19 digest 4289025870 != known digest 4190506501 2013-05-20 10:07:54.606034 osd.13 10.20.192.111:6818/20919 3453 : [ERR] 19.1b repair 0 missing, 1 inconsistent objects 2013-05-20 10:07:54.606066 osd.13 10.20.192.111:6818/20919 3454 : [ERR] 19.1b repair 2 errors, 2 fixed 2013-05-20 10:07:55.034221 osd.13 10.20.192.111:6818/20919 3455 : [ERR] 19.1b osd.13: soid 507ada1b/rb.0.6989.2ae8944a.00000000005b/5//19 digest 4289025870 != known digest 4190506501 2013-05-20 10:07:55.034224 osd.13 10.20.192.111:6818/20919 3456 : [ERR] 19.1b osd.22: soid 507ada1b/rb.0.6989.2ae8944a.00000000005b/5//19 digest 4289025870 != known digest 4190506501 2013-05-20 10:07:55.113230 osd.13 10.20.192.111:6818/20919 3457 : [ERR] 19.1b deep-scrub 0 missing, 1 inconsistent objects 2013-05-20 10:07:55.113235 osd.13 10.20.192.111:6818/20919 3458 : [ERR] 19.1b deep-scrub 2 errors Thanks, JN _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
