[ceph-users] Cephfs too many repaired copies on osds

Hi, Experts, we are using cephfs with 16.2.* with multi active mds, and recently we see an osd report “full object read crc *** != expected ox on :head” “missing primary copy of ***: will try to read copies on **” from `ceph -s`, could see OSD_TOO_MANY_REPAIRS: Too many repaired

Hi Patrick, this was all on version 17.2.7. The mon store had to be rebuilt from OSDs, so the MDS map got lost. After recovering the ceph cluster itself we inspected the journal and it reported missing objects before we continued with the disaster recovery, this was the output (I had post

Hi all, if you follow this thread, please see the update in "How to configure something like osd_deep_scrub_min_interval?" (https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/YUHWQCDAKP5MPU6ODTXUSKT7RVPERBJF/). I found out how to tune the scrub machine and I posted a quick update i

[ceph-users] Re: How to configure something like osd_deep_scrub_min_interval?

Hi all, a little gem for Christmas. After going through the OSD code, scratching my had and doing a bit of maths, I seem to have found a way to tune the built-in scrub machine to work perfectly. Its only few knobs to turn, but its difficult to find out, because the documentation is misleading t

Hi First, all requests with presigned URLs should be restricted. This is how the request is blocked with the nginx sidecar (it's just a simple parameter in the URL that is forbidden): if ($arg_Signature) { return 403 'Signature parameter forbidden'; } Our bucket policies are created automat
