If the restore consists mostly of files to be updated rather than new files, you can instruct the storage system to ignore the inode limitations.
What inodes are: Inodes are data structures that contain information about files. The number of files, and therefore the number of inodes per volume, is determined by the maxfiles command. For information about setting the maximum number of files per volume and displaying inode information, see the Data ONTAP Storage Management Guide for 7-Mode.
How the restore command handles inodes: The restore command assumes that the files being restored are added to the number of files on the storage system, and, therefore, that the inodes are added to the storage system. When the total of inodes in the restore and on a storage system exceeds the number of inodes that are allowed on a storage system, the restore is terminated.
However, if a restore updates an existing file, the inode count remains the same. Therefore, if you are sure that the restore consists mostly of files to be updated rather than new files, you can instruct the storage system to ignore the calculations of the restore command.
The following command restores a backup and ignores the inode limitations:
r performs a full restore.
f specifies that a tape device is supplied in the command line.
F specifies that you can ignore inode limitations.
rst0a is the tape device.
