lfs-getdirstripe(1)

NAME

lfs-getdirstripe - list the layout pattern of a given directory

SYNOPSIS

DESCRIPTION

Get the layout pattern of striped directories. This lfs(1) command is similar to lfs getstripe, but is used for the directory layout.

OPTIONS

-c, -T, --mdt-count

Only show the number of MDTs the directory is striped across.

-D, --default

Show the default layout used when creating new subdirectories.

-F, --fid

Show only the 128-bit unique Lustre File Identifier (FID).

-h, --help

Print usage message.

-H, --mdt-hash

Only show the hash function being used for this directory. Also shows hash flags, such as overstriping (>1 stripe per MDT).

--hex-idx

Print MDT indexes in hexadecimal rather than decimal.

-i, -m, --mdt-index

Only show the master MDT index of the directory.

-O, --obd=FSNAME-MDTnnnn_UUID

Limit the returned directories to those with objects on a specific MDT, whose UUID is FSNAME-MDTnnnn_UUID.

-r, --recursive

The default behavior when a directory is specified is to list the striping information for all sub-directories within the specified directory. This can be expanded with --recursive, which will recurse into all subdirectories.

-R, --raw

Print MDT index in raw format without converting to a name.

-v, --verbose

Print verbose information about the directory striping.

-X, --max-inherit

Show the inherit depth of default layout.

-y, --yaml

Show the layout in YAML format for easier parsing.

--max-inherit-rr

Show the inherit depth of default layout to roundrobin mkdir.

EXAMPLES

List the striping information of sub-directories, that are located on MDT1, under /mnt/lustre/dir1:

# lfs getdirstripe -O lustre-MDT0001_UUID -r /mnt/lustre/dir1
