The journal options in the tune2fs man page say: ****** CITE ********* size=journal-size Create a journal stored in the filesystem of size journal-size megabytes. The size of the journal must be at least 1024 filesystem blocks (i.e., 1MB if using 1k blocks, 4MB if using 4k blocks, etc.) and may be no more than 102,400 filesystem blocks. There must be enough free space in the filesystem to create a journal of that size. device=external-journal Attach the filesystem to the journal block device located on external-journal. The external journal must have been already created using the command mke2fs -O journal_dev external-journal Note that external-journal must be formatted with the same block size as filesystems which will be using it. In addition, while there is support for attaching multiple filesystems to a single external journal, the Linux kernel and e2fsck(8) do not currently support shared exter‐ nal journals yet. ****** CITE ********* It would be nice if the manpage included a sentence like: If an external journal is used, the whole journal block device will be used as journal. The sentence "... be no more than 102,400 filesystem blocks." gives the impression (to me, that is) that the same restrcition applies to an external-journal as well! Yes, I know *NOW* that's not the case. -- Ralf Hildebrandt Ralf.Hildebrandt@xxxxxxxxxx Charite - Universitätsmedizin Berlin Tel. +49 (0)30-450 570-155 Geschäftsbereich IT | Abt.
