This mount helper should only be invoked via the mount (8) command,
e.g. mount -t lustre dev dir
usage: mount.lustre [-fhnvV] [-o <srvopt>] <device> <mountpt>
usage: mount.lustre [-fhnvV] [-o <cliopt>] <mgstarget> <mountpt>
<device>: the local disk device when mounting a server
<mgstarget>: the server MGS and filesystem for a client:
<mgsnid>[:<altmgsnid>...]:/<filesystem>[/<subdir>]
<mgsnid>: MGS LNet Node Identifier (e.g. mgs01@o2ib)
<filesystem>: Lustre filesystem name (e.g. lustre1)
<subdir>: subdirectory of the filesystem to mount
<mountpt>: filesystem mountpoint (e.g. /mnt/lustre)
-f|--fake: fake mount (only update /etc/mtab)
-o force|--force: force mount even if already in /etc/mtab
-h|--help: print this usage message
-n|--nomtab: do not update /etc/mtab after mount
-v|--verbose: print verbose config settings
-V|--version: output build version of the utility and exit
default options are marked below with '*'
(no)flock: disable* or enable POSIX flock support
(no)user_xattr: disable or enable* user xattr namespace
<srvopt>: one or more comma separated server options:
(no)acl: disable or enable* POSIX ACL support completely
abort_recov: abort server recovery handling
nosvc: only start MGC/MGS without starting MDS/OSS
nomgs: only start target MDS/OSS, using existing MGS
noclient: do NOT allow clients connections other than MGS local
noscrub: do NOT auto start OI scrub unless requested
skip_lfsck: do NOT auto resume paused/crashed LFSCK
md_stripe_cache_size=<num>: set MD RAID device stripe cache size
<cliopt>: one or more comma separated client options:
exclude=<ostname>[:<ostname>]: list of inactive OSTs (e.g. lustre-OST0001)
localflock: enable POSIX flock only on local client
mgsname=HOSTNAME: MGS hostname for display in /proc/mounts
retry=<num>: number of times mount is retried by client
(no)user_fid2path: disable* or enable user $MOUNT/.lustre/fid access
(no)checksum: disable or enable* data checksums
(no)lruresize: disable or enable* LDLM dynamic LRU size
(no)lazystatfs: disable or enable* statfs to work if OST is unavailable
32bitapi: return only 32-bit inode numbers to userspace
(no)verbose: disable or enable* messages at filesystem (un,re)mount
Options (7)
| Option | Description | Source |
|---|
-f, --fake | Fake filesystem mount, setting client-specific parameters and adding it to /etc/fstab without actually calling the mount(2) system call. | man |
--force | Force mounting the filesystem even if it appears to already be mounted. | man |
-h, --help | Print usage message and exit. | man |
-n, --nomtab | Do not update the /etc/fstab file after the mount has successfully completed. | man |
-o, --options | Specify the list of OPTIONS to pass to the kernel for MOUNTPOINT. | man |
-v, --verbose | Print extra information during mounting. | man |
-V, --version | Print the build version of the mount.lustre binary and exit. | man |
Examples (7) from the manual page, untested
client# mount -t lustre cfs21@tcp0:/testfs /mnt/myfilesystem
Start a client for the Lustre filesystem testfs at the mount point /mnt/myfilesystem.client# mount -t lustre cfs21@tcp0:/testfs/dir /mnt/myfilesystem
Like above example, but mount subdirectory dir as fileset:client# mount -t lustre mgs1@tcp0,mgs1ib@o2ib0:mgs2@tcp0,mgs2ib@o2ib0:/testfs /mnt/fs
Like above example, but the Management Service is running on one of the service nodes mgs1 and mgs2, are two different hosts separated by a colon and served as a failover pair, and have both TCP and…mds# mount -t lustre_tgt /dev/sda1 /mnt/test/mdt
Start the Lustre metadata target service from /dev/sda1 on mountpoint /mnt/test/mdt:mds# mount -t lustre_tgt -L testfs-MDT0000 -o abort_recov /mnt/test/mdt
Start the testfs-MDT0000 service (by using the disk label), but aborts the Lustre client recovery process for the case that clients are known to be unavailable:client# mount -t lustre -o mgsname=cfs-mgs@o2ib 10.0.0.2@o2ib,10.0.0.4@o2ib:/testfs /myfs
Mount a client filesystem with a custom MGS name for display purposes.client# mount -t lustre test-mgs@o2ib:/testfs /mnt/myfs
Mount a client filesystem with automatic MGS name generation.
