NAME

convertfs − convert a file system to allow long file names

SYNOPSIS

/etc/convertfs [special_file]

DESCRIPTION

convertfs converts an existing HFS file system supporting the default maximum file name length of 14 characters into one that supports file names up to 255 characters long.  Once an HFS file system is converted to long file names, it cannot be restored to its original state, since the longer file names require a directory representation that is incompatible with the default HFS directory format.  Since this is an irreversible operation, convertfs prompts for verification before it performs a conversion. 

convertfs forces the system to be rebooted if the root file system is converted.  When converting the root file system, the system should be in single-user mode, with all unnecessary processes terminated and all non-root file systems unmounted.  Except for the root file system, convertfs requires that the file system to be converted be unmounted. 

If invoked without any arguments, convertfs interactively prompts the user with a list of the file systems from /etc/checklist.  One or more or all of the listed file systems can be selected for conversion.  Typically, it is desirable to convert all of the file systems in /etc/checklist to avoid inconsistencies between two file systems mounted on the same system. 

convertfs can also be invoked with an argument of either a block or character special_file of a file system to be converted.  Only the block special file should be specified for a mounted root file system. 

As part of the conversion process, convertfs performs an fsck on each file system (see fsck(1M)).
