Out of inodes on filesystem

An inode is an internal structure that the operating system uses to track and control information about a file, such as size and last access date. Each file uses one inode. When a filesystem runs out of inodes, the system displays the following error message:

   NOTICE: type: Out of inodes on type dev hd (major/minor)

To fix this problem:

1. Remove unnecessary (old, temporary, core, or log) files from the filesystem. See ``Maintaining free space in filesystems''.

2. Use find(C) to determine whether the filesystem contains a large number of small files.

   The initial allocation of inodes assumes a ratio of about four data blocks per inode. If the filesystem contains mostly files that are smaller than four blocks, it runs out of inodes.

To increase the number of available inodes:

1. Back up the filesystem and verify the integrity of the backup using the Backup Manager. See ``Running unscheduled filesystem backups''.

2. Unmount the filesystem. See ``Mounting and unmounting filesystems''.

3. From the command line, run mkfs(ADM) and specify more inodes for the filesystem. For example, to reconfigure the number of inodes on the /dev/u filesystem to 6400, enter:
   
   mkfs /dev/u fssize:6400

   Replace fssize with the size of the filesystem (in 512-byte blocks). See the mkfs(ADM) manual page for more information.

4. Mount the filesystem. See ``Mounting and unmounting filesystems''.

5. Restore the filesystem from the backup using the Backup Manager. See ``Restoring files or directories from backup media''.
