Hi Tobias,
thanks a lot for your input, certain improvment on the critical issue
notification process is needed indeed.
We have an active discussion in the dev community (CLT group
specifically) on how to better arrange such notifications. Perhaps it
would be good to have a wider audience for that topic - so I would
suggest to utilize Ceph User+Dev Monthly meeting which has been
advertized by Neha yesterday.
The first upcoming event to be held on Nov 18. Please feel free to join
and/or update the agenda at
https://pad.ceph.com/p/ceph-user-dev-monthly-minutes
Thanks,
Igor

As this is a very important Information it should become special
attention.
I think the risk is quite high that when such important news are
posted on ceph-users it could get lost in the shuffle.
I would propose to either create a separate Mailing list for these
kind of Information from the Ceph Dev Community or use a Mailing list
where not that much is happening, e.g. ceph-announce
What do you think?

Dear Ceph users.
On behalf of Ceph's developers community I have to inform about a
recently discovered severe bug which might cause data corruption. The
issue occurs during OMAP format conversion for clusters upgraded to
Pacific, new clusters aren't affected. OMAP format conversion's
trigger is BlueStore repair/quick-fix functionality which might be
invoked either manually via ceph-bluestore-tool or automatically by
OSD if 'bluestore_fsck_quick_fix_on_mount' is set to true.
Both OSD and MDS daemons are known to be suffering from the issue,
potentially other ones, e.g. RGW might be affected as well - the
major symptom is daemon's inability to startup/proceed operating
after some OSDs have been "repaired".
More details on the bug and its status tracking can be found at:
https://tracker.ceph.com/issues/53062
We're currently working on the fix which is expected to be available
in the upcoming v16.2.7 release.
Meanwhile please DO NOT SET bluestore_fsck_quick_fix_on_mount to true
(please immediately switch it to false if already set) and DO NOT RUN
ceph-bluestore-tool's repair/quick-fix commands.
Appologies for all the troubles this could cause.
best regards, Tobi
