mount.lustre - start a Lustre client or target service
mount -t lustre [-o options] directory
mount.lustre is used to start a Lustre client or target service. This
program should not be called directly; rather it is a helper program
invoked through mount(8) as above. Lustre clients and targets are
stopped by using the umount(8) command.
There are two forms for the device option, depending on whether a
client or a target service is started:
mounts the Lustre filesystem named fsname on the client by
contacting the Management Service at mgsspec on the pathname
given by directory. The format for mgsspec is defined below. A
mounted client filesystem appears in fstab(5) and is usable like
any local filesystem and provides a full POSIX-compilant
starts the target service defined by the mkfs.lustre command on
the physical disk disk_device. A mounted target service
filesystem is only useful for df(1) operations and appears in
fstab(5) to show the device is in use.
The mgs specification may be a colon-separated list of nodes:
each node may be specified by a comma-separated list of NIDs.
In addition to the standard options listed in mount(8), Lustre
understands the following client-specific options:
flock Enable full flock support, coherent across all client nodes.
Enable local flock support, using only client-local flock
(faster, for applications that require flock but do not run on
Disable flock support entirely. Applications calling flock will
get an error.
Enable get/set of extended attributes by regular users. See the
attr(5) manual page.
Disable use of extended attributes by regular users. Root and
system processes can still use extended attributes.
acl Enable POSIX Access Control List support. See the acl(5) manual
noacl Disable Access Control List support.
In addition to the standard mount options and backing disk type (e.g.
ext3) options listed in mount(8), Lustre understands the following
nosvc Only start the MGC (and MGS, if co-located) for a target
service, and not the actual service.
Start a client or MDT with a (colon-separated) list of known
Abort client recovery and start the target service immediately.
mount -t lustre cfs21@tcp0:/testfs /mnt/myfilesystem
Start a client for the Lustre filesystem ’testfs’ at the mount
point /mnt/myfilesystem. The Management Service is running on a
node reachable from this client via the nid cfs21@tcp0.
mount -t lustre /dev/sda1 /mnt/test/mdt
Start the Lustre metadata target service from /dev/sda1 on
mount -t lustre -L testfs-MDT0000 -o abort_recov /mnt/test/mdt
Start the testfs-MDT0000 service (by using the disk label), but
abort the recovery process.
Not very many mount options can be changed with -o remount. Please
