Increase fileset space

The system needs inodes to allow I/O on a fileset. If the inodes allocated to the fileset are exhausted, you need to either increase the number of maximum inodes or delete the existing data to free up space.

The procedure helps to increase the maximum number of inodes by a percentage of the already allocated inodes. The following are the corresponding event details and the proposed solution:
  • Event ID: inode_error_high and inode_warn_high
  • Problem: The inode usage in the fileset reached an exhausted level.
  • Solution: Increase the maximum number of inodes.
The system issues the mmchfileset command to recover NSDs as given in the following format: 
/usr/lpp/mmfs/bin/mmchfileset <Device> <Fileset> --inode-limit <inodesMaxNumber>

For example: /usr/lpp/mmfs/bin/mmchfileset r1_FS testFileset --inode-limit 2048
