NAME

       mkfs.lustre - format a disk for a Lustre service

SYNOPSIS

       mkfs.lustre{--ost|--mdt|--mgs} [options] device
       <target_type> is one of

       --ost  object storage target

       --mdt  metadata storage target

       --mgs  configuration  management  service - one per site.  This service
              can be combined with one --mdt service by specifying both types

DESCRIPTION

       mkfs.lustre is used to format a disk device for use as part of a Lustre
       filesystem. After formatting, a disk can be mounted to start the Lustre
       service defined by this command.

OPTIONS

       --backfstype=fstype
              Force a particular format for the backing fs (ext3, ldiskfs)

       --comment=comment
              Set user comment about this disk, ignored by Lustre.

       --device-size=KB
              Set device size for loop devices

       --dryrun
              Only print what would be done; does not affect the disk

       --failnode=nid,...
              Set the NID(s)  of  a  failover  partner.  This  option  can  be
              repeated as desired.

       --fsname=filesystem_name
              The Lustre filesystem this service will be part of.  The maximum
              filesystem_name length is 8 characters. Default is ’lustre’

       --index=index
              Force a particular OST or MDT index

       --mkfsoptions=opts
              Format options for the backing fs.  For  example,  ext3  options
              could be set here.

       --mountfsoptions=opts
              Set permanent mount options, equivalent to setting in /etc/fstab

       --mgsnode=nid,...
              Set the NID(s) of the MGS node, required for all  targets  other
              than the MGS.

       --param key=value
              Set  permanent parameter key to value value.  This option can be
              repeated as desired.  Typical options might include:
              --param sys.timeout=40
                     System obd timeout
              --param lov.stripesize=2M
                     Default stripe size
              --param lov.stripecount=2
                     Default stripe count
              --param failover.mode=failout
                     Return errors instead of waiting for recovery

       --quiet
              Print less information.

       --reformat
              Reformat an existing Lustre disk

       --stripe-count-hint=stripes
              Used for optizing MDT inode size

       --verbose
              Print more information.

EXAMPLES

       mkfs.lustre --fsname=testfs --mdt --mgs /dev/sda1
              Combined MGS and MDT for filesystem ’testfs’ on node e.g. cfs21

       mkfs.lustre --fsname=testfs --ost --mgsnode=cfs21@tcp0 /dev/sdb
              OST for filesystem ’testfs’ on any node using the above MGS.

       mkfs.lustre --mgs /dev/sda1
              Standalone MGS on e.g. node cfs22

       mkfs.lustre --fsname=myfs1 --mdt --mgsnode=cfs22@tcp0 /dev/sda2
              MDT for filesystem ’myfs1’ on any node, using the above MGS
