inconsistent "insufficient space" percentages on same filesystem

Support
1

I’m getting insufficient space on disk for database on several folders, but they are showing different percentages even though they are on the same filesystem:

2025-04-12 11:26:10: Error on folder "MP3" (MP3): insufficient space on disk for database (/Users/john/Library/Application Support/Syncthing/index-v0.14.0.db): current 1.00 % < required 1 %

2025-04-12 11:28:55: Error on folder "Suandjhon Downloads" (Suandjhon-Downloads): insufficient space on disk for database (/Users/john/Library/Application Support/Syncthing/index-v0.14.0.db): current 0.53 % < required 1 %

2025-04-12 11:40:21: Error on folder "Suandjhon Documents" (Suandjhon-Documents): insufficient space on disk for database (/Users/john/Library/Application Support/Syncthing/index-v0.14.0.db): current 0.66 % < required 1 %

Am I misunderstanding what the “insufficient space on disk for database” percentages refer to or could this be a bug?

Sure could be; macOS does so many funky things with reported disk space it’s hard to tell. Also, the log entries are from different times, and these things change over time. :person_shrugging:

So the %ages should all be the same for shares on the same filesystem? It did seem later to settle down to the same %age for each so I guess it was still eating up disk space between one notification and the next, although in the snippet I posted the space %age wasn’t monotonically decreasing, which puzzled me. Thanks for the prompt reply.
