mmlsfileset Command Name mmlsfileset – Displays attributes and status for GPFS filesets. Synopsis mmlsfileset Device {[[Fileset [,Fileset ...]] [-J Junction [,Junction ...]] | -F FileName} [-L] [-d] [-i] Description Use the mmlsfileset command to display information for the filesets that belong to a given GPFS file system. The default is to display information for all filesets in the file system. You may choose to display information for only a subset of the filesets. The operation of the -L flag omits the attributes listed without it, namely status and junction path. In addition, if the fileset has status 'deleted', then -L also displays the name of the latest snapshot that includes the fileset in place of the root inode number and parent fileset identifier. The attributes displayed are: v Name of the fileset v Status of the fileset (when the -L flag is omitted) v Junction path to the fileset (when the -L flag is omitted) v Fileset identifier (when the -L flag is included) v Root inode number, if not deleted (when the -L flag is included) v Parent fileset identifier, if not deleted (when the -L flag is included) v Latest including snapshot, if deleted (when the -L flag is included) v Creation time (when the -L flag is included) v Number of inodes in use (when the -i flag is included) v Data size (in KB) (when the -d flag is included) v Comment (when the -L flag is included) For information on GPFS filesets, see the chapter Policy-based data management for GPFS in General Parallel File System: Advanced Administration Guide. Parameters Device The device name of the file system that contains the fileset. File system names need not be fully-qualified. fs0 is as acceptable as /dev/fs0. This must be the first parameter. Fileset Specifies a comma-separated list of fileset names. -J Junction Specifies a comma-separated list of path names. They are not restricted to fileset junctions, but may name any file or directory within the filesets to be listed. -F FileName Specifies the name of a file containing either fileset names or path names. Each line must contain a single entry. All path names must be fully-qualified. 206 GPFS: Administration and Programming Reference
Options -d Display the number of blocks in use for the fileset. -i Display the number of inodes in use for the fileset. -L Display additional information for the fileset. This includes: Exit status v Fileset identifier v Root inode number v Parent identifier v Fileset creation time v User defined comments, if any 0 Successful completion. nonzero A failure has occurred. Security You may issue the mmlsfileset command from any node in the GPFS cluster. When using the rcp and rsh commands for remote communication, a properly configured .rhosts file must exist in the root user’s home directory on each node in the GPFS cluster. If you have designated the use of a different remote communication program on either the mmcrcluster or the mmchcluster command, you must ensure: 1. Proper authorization is granted to all nodes in the GPFS cluster. 2. The nodes in the GPFS cluster can communicate without the use of a password, and without any extraneous messages. Examples 1. This command displays fileset information for all filesets in file system gpfs1: mmlsfileset gpfs1 The system displays information similar to: Filesets in file system ’gpfs1’: Name Status Path root Linked /gpfs1 fset1 Linked /gpfs1/fset1 fset2 Linked /gpfs1/fset1/fset2 2. The file Filesetlist has this information: fset1 fset2 This command displays all filesets in file system gpfs1 that are listed in Filesetlist: mmlsfileset gpfs1 -F Filesetlist The system displays information similar to: Filesets in file system ’gpfs1’: Name Status Path fset1 Linked /gpfs1/fset1 fset2 Linked /gpfs1/fset1/fset2 mmlsfileset Command Chapter 8.
