Lustre 1.6 Operations Manual

Option
Description
setstripe
Create a new file or sets the directory default with the specified
striping parameters. †
stripe-size *
Number of bytes to store on an OST before moving to the next OST.
A stripe size of 0 uses the filesystem’s default stripe size, 1MB. Can
be specified with k, m or g (in KB, MB or GB, respectively).
stripe-count
Number of OSTs to stripe a file over. A stripe count of 0 uses the
filesystem-wide default stripe count (1). A stripe count of -1 stripes
over all available OSTs.
stripe-ost *
The OST index (base 10, starting at 0) on which to start striping for
this file. A start-ost of -1 allows the MDS the choose the starting
index. Selecting this value is strongly recommended, as this allows
space and load balancing to be done by the MDS as needed.
pool-name
setstripe -d
Name of the pre-defined pool of OSTs (see lctl) that will be used for
striping. The stripe-count, stripe-size and start-ost values are used
as well. The start-ost must be part of the pool or an error is returned.
For more information, see OST Pools.
Deletes default striping on the specified directory.
poollist [.] |
Lists pools in the filesystem or pathname, or OSTs in the filesystem’s
pool.
quota [-v] [-o obd_uuid] [-u|-g]
quota -t [-u|-g]
quotacheck [-ugf]
Displays disk usage and limits, either for the full filesystem or for
objexts on a specific OBD. A user or group name can be specified. If
both user and group are omitted, quotas for the current UID/GID are
shown. The -v option provides more verbose (with per-OBD
statistics) output.
Displays block and inode grace times for user (-u) or group (-g)
quotas.
Scans the specified filesystem for disk usage, and creates or updates
quota files. Options specify quota for users (-u), groups (-g), and
force (-f).
