What Is The Default Size Of Journals In Gfs? |
|
Answer» When you run mkfs.gfs2 WITHOUT the size attribut for journal to create a GFS2 partition, by default a 128MB size journal is created which is enough for most of the applications In case you PLAN on reducing the size of the journal, it can severely affect the performance. SUPPOSE you reduce the size of the journal to 32MB it does not take MUCH FILE system activity to fill an 32MB journal, and when the journal is full, performance slows because GFS2 has to wait for writes to the storage.
