** Description changed:
[Impact]
Multi-block transaction could fail during unexpected power down
in this case, it should be stop replaying this log instead of throwing
unrecoverable error
[Test Case]
It's too difficult to simulate power outage during multi-block transaction on
disk, so the way I test this patch is to simulate a multi-block transaction and
trigger a decode error in
try {
- auto p = bl.cbegin();
- decode(t, p);
- seen_recs = true;
- }
+ auto p = bl.cbegin();
+ decode(t, p);
+ seen_recs = true;
+ }
Add the following line right after decode(t, p) to throw an error
throw buffer::malformed_input("error test");
According to the patch description https://github.com/ceph/ceph/pull/42830
this error will be considered as a normal bluefs log reply stop condition and
will *not* prevent OSD from starting
After the error test is triggered, OSD can still be started normally
[Where problems could occur]
- This upstream PR was created 2 months ago and Luminous was EOL upstream for a
while
- so Luminous Bluefs code is outdated, in order to backport this commit
- it might also need to backport some dependencies
+ This upstream PR was created 2 months ago and Luminous was EOL upstream for a
