LTFS-SDE(8) IBM Storage Archive Command Reference LTFS-SDE(8) NAME ltfs - File system based on a linear tape drive SYNOPSIS ltfs mount_point [ -o mount_option... ] [ -V ] [ -h ] [ -a ] DESCRIPTION ltfs is a file system for linear tape drive. GENERAL OPTIONS These programs follow the usual GNU command line syntax, with long op- tions starting with two dashes ('-'). A summary of options is included below. For a complete description, see the Info files. -V, --version Version information -h, --help Show help information -a Full help, including advanced options LTFS OPTIONS (MOUNT OPTIONS) These programs follow the usual GNU command line syntax, with long op- tions starting with two dashes ('-'). A summary of options is included below. For a complete description, see the Info files. -o devname=name Tape device name. On Linux, name is like '/dev/IBMtape0', on OSX, name is like '0'(default: ) -o work_directory=dir LTFS work directory (default: ) -o trace Enable diagnostic output (same as verbose=3) -o eject Eject the cartridge after unmount -o sync_type=type Specify sync type (default: time@5). type should be specified as follows: time@min LTFS attempts to write an index each 'min' minutes. min should be a decimal number from 1 to 153722867280912930. It is equivalent to "-o sync_type=unmount" when 0 is specified close LTFS attempts to write an index when a file is closed unmount LTFS attempts to write an index when the medium is un- mounted -o force_mount_no_eod Skip EOD existence check when mounting (read-only mount). Only use for a CM corrupted medium -o device_list Show available tape devices -o rollback_mount=gen Attempt to mount on previous index generation (read-only mount) -o release_device Clear device reservation (should be specified with -o devname -o symlink_type=type Specify symbolic link type (default: posix) type should be specified with one of the following values: posix LTFS behavior is same as standard symbolic link live LTFS replaces mount point path by current mount point FUSE OPTIONS (MOUNT OPTIONS) These programs follow the usual GNU command line syntax, with long op- tions starting with two dashes ('-'). A summary of options is included below. For a complete description, see the Info files. -o umask=M Set file permissions (octal) -o uid=N Set file owner -o gid=N Set file group ADVANCED LTFS OPTIONS (EXPERIMENTAL MOUNT OPTIONS) The options described here is experimental functions. These programs follow the usual GNU command line syntax, with long op- tions starting with two dashes ('-'). A summary of options is included below. For a complete description, see the Info files. -o config_file=file Configuration file (default: ) -o atime Update index if only access times have changed -o noatime Do not update index if only access times have changed (default) -o tape_backend=name tape backend to use (default: ) -o iosched_backend=name I/O scheduler implementation to use (default: , use "none" to disable) -o kmi_backend=name Key manager interface implementation to use (default: none, use "none" to disable) -o umask=mode Override default permission mask (3 octal digits, default: 000) -o fmask=mode Override file permission mask (3 octal digits, default: 000) -o dmask=mode Override directory permission mask (3 octal digits, default: 000) -o min_pool_size=num Minimum write cache pool size. Cache objects are 1 MB each (de- fault: 25) -o max_pool_size=num Maximum write cache pool size. Cache objects are 1 MB each (de- fault: 50) -o rules=rules Rules for choosing files to write to the index partition. The syntax of the rule argument is: size=1M size=1M/name=pattern size=1M/name=pattern1:pattern2:pattern3 A file is written to the index partition if it is no larger than the given size AND matches at least one of the name patterns (if specified). The size argument accepts K, M, and G suffixes. Name patterns might contain the special characters '?' (match any single character) and '*' (match zero or more characters). -o quiet Disable informational messages (same as verbose=1) -o syslogtrace Enable diagnostic output to stderr and syslog(same as ver- bose=303) -o fulltrace Enable full call tracing (same as verbose=4) -o verbose=num Override output verbosity directly (default: 2) -o noeject Do not eject the cartridge after unmount (default) -o capture_index Capture latest index to work directory at unmount -o scsi_append_only_mode=on|off Set the tape device append-only mode (default=on) SEE ALSO mkltfs(8), ltfsck(8), mount.fuse(8), fusermount(1), tape-backend(4), kmi-backend(4), ltfs.conf(5).
