Lustre 1.6 Operations Manual

Lustre target
The CSV line format is:
hostname, module_opts, device name, mount point, device type, fsname, mgs nids, index,
format options, mkfs options, mount options, failover nids
Where:
Variable
Supported Type
hostname Hostname of the node in the cluster. It must match uname -n
module_opts
device name
mount point
device type
fsname
mgs nids
index
format options
mkfs options
mount options
failver nids
Lustre networking module options. Use the newline character (\n) to
delimit multiple options.
Lustre target (block device or loopback file).
Lustre target mount point.
Lustre target type (mgs, mdt, ost, mgs|mdt, mdt|mgs).
Lustre filesystem name (limit is 8 characters).
NID(s) of the remote mgs node, required for MDT and OST targets; if
this item is not given for an MDT, it is assumed that the MDT is also an
MGS (according to mkfs.lustre).
Lustre target index.
A ‘catchall’ contains options to be passed to mkfs.lustre. For example:
device-size, --param, and so on.
Format options to be wrapped with --mkfsoptions= and passed to
mkfs.lustre.
If this script is invoked with -m option, then the value of this item is
wrapped with --mountfsoptions= and passed to mkfs.lustre;
otherwise, the value is added into /etc/ fstab
NID(s) of the failover partner node.
Note – In one node, all NIDs are delimited by commas (','). To use comma-separated
NIDs in a CSV file, they must be enclosed in quotation marks, for example:
"lustre-mgs2,2@elan"
When multiple nodes are specified, they are delimited by a colon (':').
If you leave a blank, it is set to default.
