Hi, I am working on a custom board running Linux 2.4.19. The filesystem is EXT3 which is configured to journal meta data only. During the booting up of the board, sometimes I saw the mount command takes a long time (about 5 seconds or so).
I think this delay is due to the previous unexpected shutdown, e.g. due to power-cycle of the system, etc, some filesystem data blocks are logged in the journal log and have not been flushed onto the disk, and during the mount command, the are being written back to the disk. My questions is whether we can control when to flush the data from the log to the disk. For example, can sync command be modified to do that? Are there any filesystem IOCTL I can use to flush the journal? Thanks. Regards, Terry L. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
