The code to replay the journal is in /sbin/jfs_fsck, not in the mount code. The entries in /etc/fstab should have a non-zero value in the last field (usually 2). If fstab is set up this way, the init scripts should be running fsck against the partitions before it attempts to mount them. > We are planning on moving back down to 2.4.27 on this machine for > further testing; would that move potentially resolve issues or create more?
