Fails setting up Pebble storage engine upon restart, complaining about a file not being known to the object storage provider 000034.

The file doesn't show up in the local FS, perhaps because it is mean to be remote?

This is potentially concerning? cc @pav-kv when you have a chance could you take a quick look.

This test emulates a crash by effectively switching off disk flushes/fsyncs. Possibly a bug in the test or the in-memory test-only storage that implements this switch-off.
