Filesystem
From The Linux Source
create filesystem
Before enterprise 6 # mke2fs -t ext3 /dev/pri/arsystem OR for ent6 # mke2fs -t ext4 /dev/pri/arsystem OR for ent7 # mke2fs -t xfs /dev/pri/arsystem
increasing inodes
if a filesystem has run out of inodes (df -i), the filesystem has to be recreated, there is currently no way to increase the inode limit on an existing filesystem. when the filesystem is created, the bytes per inode ratio (16384 is the default) needs to be modified (use appropriate filesystem type, see "create filesystem" above)
# mke2fs -t ext4 -i 4096 /dev/pri/arsystem
