New page

Writing repeatedly to a small number of journal blocks instead of all over the disk may prematurely "wear out" the storage device.

A journaling filesystem with its journal disabled may be a good choice. JFS and reiserfs seem to have options to do this. ext2 is definitely not journaled, so I'm creating filesystems like so:

mkfs.ext2 -b 1024 -T ext2 -i 8192 -O dir_index,filetype,resize_inode,sparse_super /dev/vg00/usr

Explanation:
;-b 1024 : specifies a one Kibyte block size
;-T ext2 : marks this as a ext2 filesystem. No journal, no extents, no cool 2005 and newer stuff.
;-i 8192 : says to create one inode for every 8192 block of filesystem space. It would be great if ext2 would dynamically create inodes like JFS or reiserfs do, but it doesn't.
;-O dir_index,filetype,resize_inode,sparse_super : turn on indexed directories, filetypes in dirents, filesystem resizing support, and the creation of fewer than normal superblock copies
