Reverse path name lookup
The reverse path name lookup feature obtains the full path name of a file or
directory from the inode number of that file or directory. The inode number is
provided as an argument to the vxlsino administrative command, or the
vxfs_inotopath_gen(3) application programming interface library function.
The reverse path name lookup feature can be useful for a variety of applications,
such as for clients of the VxFS File Change Log feature, in backup and restore
utilities, and for replication products. Typically, these applications store
information by inode numbers because a path name for a file or directory can be
very long, thus the need for an easy method of obtaining a path name.
An inode is a unique identification number for each file in a file system. An inode
contains the data and metadata associated with that file, but does not include the
file name to which the inode corresponds. It is therefore relatively difficult to
determine the name of a file from an inode number. The ncheck command provides
a mechanism for obtaining a file name from an inode identifier by scanning each
directory in the file system, but this process can take a long period of time. The
VxFS reverse path name lookup feature obtains path names relatively quickly.
Note: Because symbolic links do not constitute a path to the file, the reverse path
name lookup feature cannot track symbolic links to files.
Because of the possibility of errors with processes renaming or unlinking and
creating new files, it is advisable to perform a lookup or open with the path name
and verify that the inode number matches the path names obtained.
See the vxlsino(1M), vxfs_inotopath_gen(3), and vxfs_inotopath(3) manual
pages.
