Description of problem: I'm not sure what "-j" does, but it says I can use it: lvm> lvchange One or more of -a, -C, -j, -m, -M, -p, -r, --refresh, --alloc, --addtag or --deltag required lvm> lvchange -h lvchange: Change the attributes of logical volume(s) lvchange [-A|--autobackup y|n] [-a|--available [e|l]y|n] [--addtag Tag] [--alloc AllocationPolicy] [-C|--contiguous y|n] [-d|--debug] [--deltag Tag] [-f|--force] [-h|--help] [--ignorelockingfailure] [-M|--persistent y|n] [--major major] [--minor minor] [-P|--partial] [-p|--permission r|rw] [-r|--readahead ReadAheadSectors] [--refresh] [-t|--test] [-v|--verbose] [--version] LogicalVolume[Path] [LogicalVolume[Path]...] lvm> lvchange -j /dev/gfs/testvol Invalid argument /dev/gfs/testvol Error during parsing of command line. lvm> lvchange -jy /dev/gfs/testvol Invalid argument y Error during parsing of command line. lvm> lvchange -j 1 /dev/gfs/testvol --major and --minor require -My
