Hi, I'm trying to understand the "commit=nrsec" mount option. I had thought that it controlled the time between commits of journaled metadata to its permanent location in disk. However, the kernel documentation says: """ Ext4 can be told to sync all its data and metadata every 'nrsec' seconds. The default value is 5 seconds. This means that if you lose your power, you will lose as much as the latest 5 seconds of work (your filesystem will not be damaged though, thanks to the journaling). """ This suggests that both metadata and data get committed every nrsec seconds. But my understanding was that in the default "data=ordered,delalloc" mode, metadata gets commited every 5s, and data every 30s. Could someone please clarify?
