MKLTFS(8) IBM Storage Archive Command Reference MKLTFS(8) NAME mkltfs - Format a tape in the drive to LTFS format SYNOPSIS mkltfs -d name [ -f ] [ -s id ] [ -n name ] [ -r rules ] [ -w ] [ -q ] [ -t ] [ -V ] [ -h ] [ -p ] DESCRIPTION mkltfs is a program to format a media for use with the IBM Storage Archive. 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. -d, --device=name Tape device name (required). On Linux, name is like '/dev/IBM- tape0', on OSX, name is like '0' -f, --force Force to format medium -s, --tape-serial=id Tape serial number (6 alphanumeric ASCII characters) -n, --volume-name=name Tape volume name (empty by default) -r, --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). --no-override Disallow mount-time data placement policy changes -w, --wipe Restore the LTFS medium to an unpartitioned medium (format to a legacy scratch medium) -q, --quiet Suppress progress information and general messages -t, --trace Enable function call tracing --syslogtrace Enable diagnostic output to stderr and syslog -V, --version Version information -h, --help Show help information -p, --advanced-help Full help, including advanced options USAGE EXAMPLE /home/piste/ltfs05-sde/bin/mkltfs --device=/dev/IBMtape0 --rules="size=100K" /home/piste/ltfs05-sde/bin/mkltfs --device=/dev/IBMtape0 --rules="size=1M/name=*.jpg" /home/piste/ltfs05-sde/bin/mkltfs --device=/dev/IBMtape0 --rules="size=1M/name=*.jpg:*.png" ADVANCED OPTIONS (EXPERIMENTAL) 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. -i, --config=name Use the specified configuration file (default: ) -e, --backend=name Use the specified tape device backend (default: ) --kmi-backend=name Use the specified key manager interface backend (default: none) -b, --blocksize=num Set the LTFS record size (default: 524288) -c, --no-compression Disable compression on the volume -k, --keep-capacity Keep the tape medium's total capacity proportion -x, --fulltrace Enable full function call tracing (slow) --long-wipe Unformat the medium and erase any data on the tape by overwrit- ing special data pattern. This operation takes over 3 hours. Once you start, you cannot interrupt it. --destructive Use destructive format/unformat. This operation takes longer time in the LTO9 drive or later because of the media optimiza- tion procedure. SEE ALSO ltfs-sde(8), ltfsck(8), tape-backend(4), kmi-backend(4), ltfs.conf(5).
