Tentatively assigning @postamar - this could be a good entrance point into some new parts of the code.

SpeedyCoder · 2021-01-13T13:37:08Z

Hey, based on dates and database version I think it was our database that triggered the duplicate issue above #57779. It seems like trying to query all but migration tables in the database causes this exception. Let me know if there is any way we can help resolve this issue. Also is there any way to fix this at the moment without downgrading the cluster?

nick-jones · 2021-01-14T11:21:37Z

@jordanlewis Hi, any comment on the above? We'd like to start recovery steps for this database, so not planning to leave it in this state for too much longer.

Also, any indication what causes this issue?

I believe I've identified the cause of the problem. Affected versions are v20.2.x. I submitted a PR targeting the release-20.2 branch with a fix, if it's accepted it should make it into the subsequent 20.2 patch release.

Sorry for taking so long on this.

Previously, catalog.FilterDescriptorState was sometimes called with a nil descriptor interface. This patch fixes this. This bug only affects v20.2.x. Fixes cockroachdb#57639. Release note (bug fix): Fixed a nil pointer panic bug involving catalog.FilterDescriptorState. This bug affected version 20.2 since v20.2.0.

Hi @nick-jones, thanks for that information.

Was the database that's having problems created on a different cluster version than the others? Or is there anything else special about it that you're aware of?

It would be helpful if you could send us a debug zip. This will contain some sensitive information (metadata), so you can send it to us at [email protected] if you'd prefer to not attach it to this issue.

Previously, catalog.FilterDescriptorState was sometimes called with a nil descriptor interface. This patch fixes this. This bug only affects v20.2.x. Fixes cockroachdb#57639.

@lucy-zhang -

We cannot think of anything particularly unusual about this database. We're not sure if it was created against a different cluster version, unfortunately.

It would be helpful if you could send us a debug zip. This will contain some sensitive information (metadata), so you can send it to us at [email protected] if you'd prefer to not attach it to this issue.

No problem, I've emailed it over 👍

thoszhang · 2021-01-28T01:38:01Z

The panic was fixed in #58998. The root cause of the descriptor corruption is unclear. There are pairs of doctor errors like this:

Table <id1>: ParentID <db>, ParentSchemaID <schema>, Name '<name>': not being dropped but no namespace entry found
Descriptor <id2>: has namespace row(s) [{ParentID:<db> ParentSchemaID:<schema> Name:<name>}] but no descriptor

id1 and id2 are not equal (despite them presumably corresponding logically to the "same" table), hence the panic after
retrieving the namespace entry. What's interesting is that the ReplacementOf table ID (formerly, the previous ID of a truncated table) for the descriptor id1 is sometimes id2, but sometimes not.

This points to a truncate-related bug (in the old implementation). There's no DropJobID on these descriptors, though, so it's not #50587 (and other symptoms don't add up). It's also possible there are two different bugs/sources of corruption here.

We don't have any further information to act on, so I'm closing this, but if we see something similar again we can compare.
