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 options 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/IBMtape0', 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 syn- tax 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 speci- fied). The size argument accepts K, M, and G suffixes. Name patterns might contain the special characters '?' (match any single charac- ter) 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 options 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 overwriting 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 optimization procedure. SEE ALSO ltfs-sde(8), ltfsck(8), tape-backend(4), kmi-backend(4), ltfs.conf(5).
