convertfs(1M) convertfs(1M) NAME
convertfs - convert an HFS file system to allow long file names SYNOPSIS
[special-file] DESCRIPTION
The command 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, prompts for verification before it performs a conversion. forces the system to reboot 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, requires that the file system to be converted be unmounted. If invoked without arguments, interactively prompts the user with a list of the HFS file systems from 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 to avoid inconsistencies between two file systems mounted on the same system. can also be invoked with an argument of either a block or character special-file name for 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, performs an on each file system (see fsck(1M)). Options Do it quietly. will perform the conversions without querying the user. Normally prompts the user before converting a file system. RETURN VALUE
returns the following values: Success. Either successfully converted the file system, or the file system already allowed long file names. Failure. was not able to convert the file system due to some failure in processing. AUTHOR

fsck.hfs -- HFS file system consistency check SYNOPSIS
fsck.hfs -q [-df] special ... fsck.hfs -p [-df] special ... fsck.hfs [-n | -y | -r] [-dfgl] [-m mode] [-c size] special ... DESCRIPTION
The fsck.hfs utility verifies and repairs standard HFS and HFS+ file systems. The first form of fsck.hfs quickly checks the specified file systems to determine whether they were cleanly unmounted. The second form of fsck.hfs preens the specified file systems. It is normally started by fsck(8) during systen boot, when a HFS file system is detected. When preening file systems, fsck.hfs will fix common inconsistencies for file systems that were not unmounted cleanly. If more serious problems are found, fsck.hfs does not try to fix them, indicates that it was not successful, and exits. The third form of fsck.hfs checks the specified file systems and tries to repair all detected inconsistencies. If no options are specified fsck.hfs will always check and attempt to fix the specified file systems. The options are as follows: -c size Specify the size of the cache used by fsck.hfs internally. Bigger size can result in better performance but can result in deadlock when used with -l option. Size can be specified as a decimal, octal, or hexadecimal number. If the number ends with a ``k'', ``m'', or ``g'', the number is multiplied by 1024 (1K), 1048576 (1M), or 1073741824 (1G), respectively. -d Display debugging information. This option may provide useful information when fsck.hfs cannot repair a damaged file system. -f When used with the -p option, force fsck.hfs to check `clean' file systems, otherwise it means force fsck.hfs to check and repair journaled HFS+ file systems. -g Causes fsck.hfs to generate its output strings in GUI format. This option is used when another application with a graphical user interface (like Mac OS X Disk Utility) is invoking the fsck.hfs tool. -l Lock down the file system and perform a test-only check. This makes it possible to check a file system that is currently mounted, although no repairs can be made. -m mode Mode is an octal number that will be used to set the permissions for the lost+found directory when it is created. The lost+found directory is only created when a volume is repaired and orphaned files or directories are detected. fsck.hfs places orphaned files and directories into the lost+found directory (located at the root of the volume). The default mode is 01777. -p Preen the specified file systems. -q Causes fsck.hfs to quickly check whether the volume was unmounted cleanly. If the volume was unmounted cleanly, then the exit status is 0. If the volume was not unmounted cleanly, then the exit status will be non-zero. In either case, a message is printed to standard output describing whether the volume was clean or dirty. -y Always attempt to repair any damage that is found. -n Never attempt to repair any damage that is found. -r Rebuild the catalog file on the specified file system. This option currently will only work if there is enough contiguous space on the specified file system for a new catalog file and if there is no damage to the leaf nodes in the existing catalog file.
