[ceph-users] Re: radosgw-admin user create takes a long time (with failed to distribute cache message)

Hi, since a couple of days we experience a strange slowness on some radosgw-admin operations. What is the best way to debug this? For example creating a user takes over 20s. [root@s3db1 ~]# time radosgw-admin user create --uid test-bb-user --display-name=test-bb-user 2021-05-05 14:08:14.297 7f6942286840 1 robust_notify: If at first you don't succeed: (110) Connection timed out 2021-05-05 14:08:14.297 7f6942286840 0 ERROR: failed to distribute

Also uploading to buckets is fine. We changed some things and I think it might have to do with this: * We have a HAProxy that distributes via leastconn between the 3

(this did not change) * We had three times a daemon with the name "eu-central-1" running (on

3 radosgw's) * Because this might have led to our data duplication problem, we have split that up so now the daemons are named per host (eu-central-1-s3db1, eu-central-1-s3db2, eu-central-1-s3db3) * We also added dedicated rgw daemons for garbage collection, because

current one were not able to keep up. * So basically ceph status went from "rgw: 1 daemon active

to "rgw: 14 daemons active (eu-central-1-s3db1, eu-central-1-s3db2, eu-central-1-s3db3, gc-s3db12, gc-s3db13...) Cheers Boris
