Increasing inodes in HFS FS

[suki]

Hi,
I have a HP-UX 10.20 System with HFS FS. In one of my HFS FS the free inode is only 5% . The FS is using a full 4GB HDD without LVM.I need to increase the No of inodes so as there won't be any problem when creating new files. Please let me know the steps to be perform to increase the HFS FS inodes.
Thanks,
suki

There is no magic bullet here. You have to backup, create a new filesystem, and restore. Unlike vxfs which can dynamically increase the number of inodes, hfs is static. If it were me, I would backup and create a vxfs filesystem to replace your existing one. Even on 10.20, in almost everycase, vxfs will outperform hfs.

You will have to recreate the file system in order to increase the no. of inodes.
and once created, you will have to restore the backup.

check the man page for mkfs_hfs/newfs_hfs

you specify the no. of inodes with -i option.

Unfortunately if a filesystem does run out of inodes there are only three
possibilities to rectify the situation:

1. Move or delete files within the filesystem to free up inodes currently in
use.

2. Recreate the filesystem with more inodes. This will require the data to be restored after running newfs(1m) again.

3. Extend the size of the filesystem.

NOTE: Increasing the size of the filesystem will allocate inodes at the same
nbpi rate the filesystem was originally created with. For this reason,
extending the filesystem may be a temporary solution.
