mdtcount

Panel
titlemdtcount | Integer

The total number of MDTs to create on each MDSacross all of the MDSs.

Valid values: 1 - 4 per MDS

Code Block
themeMidnight
# create 4 MDTs per MDS
mdscount=2 mdtcount=8 MDTs on each

# create 1 MDT per MDS
mdscount=4 mdtcount=4
Panel
titlemdtfilesystemtype | String

Configure the file system type to use on the MDTs.

NOTE: <mdt/mgt/ost>filesystemtype should not be used in combination with fstype.

Valid values: ldiskfs, zfs

# configure the MDTs to use zfs
mdtfilesystemtype=zfs

# configure the MDTs to use ldiskfs
mdtfilesystemype=ldiskfs

# this may result in an unexpected configuration
fstype=zfs mdtfilesystemtype=ldiskfs

titlecount | Integer

The number of nodes to use for the specified node type.

NOTE: For MDS and OSS nodes, it's best to also set mdtcount / ostcount to ensure you have the expected number of targets.

Valid values:

clientcount2 - 4
mdscount1 - 4
osscount1 - 4
Code Block
themeMidnight
# configure session to run with 4 clients, 2 MDSs and 1 OSS
