Cryptic error message when journal is full
Yesterday we got hit with an error that stopped our zone from being propagated from signer to hidden masters. This was the only error in our logs, appearing every 20 minutes when we generate a new zone:
May 4 11:50:04 ht-tldsigner01 knot[8679]: info: [is.] DNSSEC, signing started
May 4 11:50:22 ht-tldsigner01 knot[8679]: info: [is.] DNSSEC, successfully signed
May 4 11:50:23 ht-tldsigner01 knot[8679]: error: [is.] zone event 'load' failed (not enough space provided)
After a couple of hours we tracked the issue down to us still having the default setting for journal-max-usage, which was stupid since we have one enormous zone.
Searching for the error turned up very little, and looking through the code didn't help much since it seems to be thrown for different things. It would help if the error was more specific (not enough space in journal) or something in the guide with hints on what to look for when the error is thrown.
