We are planning an upgrade after oVirt 3.6.3 goes GA.

We are running a pretty old version already.  Worth going over the changelog from our version up to see if there is a fix relevant to corruption.

Hello All.

We have a potentially nasty thing happened in u/s gerrit.

Here is what I got from msivak:

<msivak> Gerrit-MessageType: comment
<msivak> Gerrit-Change-Id: I1372ad145a356bdc181ba4f63987e116c6f8995b
<msivak> Gerrit-PatchSet: 5
<msivak> Gerrit-Project: ovirt-engine
<msivak> Gerrit-Branch: master

He is in reviewers for this change. But I was not able to locate in in the gerrit UI.

Going to the database also did not find it:

gerrit> select * from changes where change_key='I1372ad145a356bdc181ba4f63987e116c6f8995b';
 change_key | created_on | last_updated_on | sort_key | owner_account_id | dest_project_name | dest_branch_name | open | status | current_patch_set_id | subject | topic | row_version | change_id | last_sha1_merge_tested | mergeable
 -----------+------------+-----------------+----------+------------------+-------------------+------------------+------+--------+----------------------+---------+-------+-------------+-----------+------------------------+----------
(0 rows; 1 ms)

However looking at our backups I can confirm that indeed it was there:

[root@gerrit database]# cat gerrit-pg-dump-20160223.sql | grep I1372ad145a356bdc181ba4f63987e116c6f8995b
I1372ad145a356bdc181ba4f63987e116c6f8995b    2016-01-13 16:39:59.148-05    2016-01-26 09:34:56.706-05    003abf0a0000ca6a    1000070    ovirt-engine    refs/heads/master    Y    d    3    core: Remove redundant equals() implementation in PendingResource subs    \N    296    51818    7da9fc9fb6dadf2767724237bb78131a30197c34    N

So sounds like we lost it and it seems dangerous to me.

I do not yet have any ideas on how this might have happen. So FYI and let me know if you have any ideas.

Anton.
