Do you mean display the process that has a file (access file name by inode) open?
An inode all by itself is part of the file system and has no relation to a process except when something has the file open. You also have to know which filesystem you have the inode from. Inode numbers are not unique systemwide, they are only unique inside one filesystem

Assuming what I said, assume your inode is 42:
Code:
fname=$(find /path/to/filesystem -inum 42 -print \;)

You now have a filename. You can use lsof or fuser to see what process, if any, has the file open. The presence lsof and fuser depend on what flavor of unix you have.

xfs_ncheck(8)                                                 System Manager's Manual                                                xfs_ncheck(8)

NAME
xfs_ncheck - generate pathnames from i-numbers for XFS SYNOPSIS
xfs_ncheck [ -i ino ] ... [ -f ] [ -s ] [ -l logdev ] device DESCRIPTION
xfs_ncheck with no -i arguments generates an inode number and pathname list of all files on the given filesystem. Names of directory files are followed by /.. The output is not sorted in any particular order. The filesystem to be examined is specified by the device argument, which should be the disk or volume device for the filesystem. Filesystems stored in files can also be checked, using the -f flag. OPTIONS
-f Specifies that the filesystem image to be processed is stored in a regular file at device (see the mkfs.xfs -d file option). This might happen if an image copy of a filesystem has been made into an ordinary file. -l logdev Specifies the device where the filesystem's external log resides. Only for those filesystems which use an external log. See the mkfs.xfs -l option, and refer to xfs(5) for a detailed description of the XFS log. -s Limits the report to special files and files with setuserid mode. This option may be used to detect violations of security pol- icy. -i ino Limits the report to only those files whose inode numbers follow. May be given multiple times to select multiple inode numbers. If the filesystem is seriously corrupted, or very busy and looks like it is corrupt, a message of the form that would be generated by xfs_check(8) may appear. xfs_ncheck is only useful with XFS filesystems.
