Utility to Mount VMFS File Systems
mount-vmfs is a program that mounts VMFS (VMware ESX Server File System) file
systems. It is useful for automatically mounting partitions with valid VMFS file systems
on the console operating system.
In its simplest usage, mount-vmfs does not take any arguments. It checks every
SCSI device available to virtual machines for valid file systems. If a valid file system is
found, mount-vmfs mounts it at /vmfs/vmhba<a>:<t>:<l>:<p>, where
<a> specifies the SCSI adapter number, <t> specifies the SCSI target, <l> specifies
the LUN (logical unit number) and <p> specifies the disk partition. If the disk has no
partitions and the disk has a valid file system, <p> is zero.
If a partition has an associated file system name (vmkfstools -S), then
mount-vmfs also creates a symbolic link from /vmfs/<fsname> to the
corresponding mount point (/vmfs/vmhba<a>:<t>:<l>:<p>).
The reverse operation — unmounting all VMFS partitions — can be performed by
executing umount-vmfs.
By default, mount-vmfs does not mount any VMFS file systems that have the shared
or public attribute. File systems with these attributes set are intended to be accessed
by multiple ESX Server computers. Thus, it does not make sense to mount these file
systems automatically on any one server. However, mount-vmfs will also mount
any such file systems if you include the -f flag on the command line.
In addition, an individual file system can be mounted explicitly by supplying its device
name or file system name as an argument to mount-vmfs. The format for the
command is
mount-vmfs vmhba0:2:0:1
This mounts the file system on the specified partition if that partition holds a VMFS file
system.
You can use the regular mount command to mount VMFS file systems. The file
system type is vmfs and the device name is vmhba<a>:<t>:<l>:<p>. The
format for the command is
mount -t vmfs vmhba0:1:0:2 /vmfs/vmhba0:1:0:2
This mounts partition 2 of the disk with target 1 on the adapter vmhba0.
Although VMFS file systems may appear similar to any other file system such as ext2,
VMFS is mainly intended to store large files such as disk images. It does not support
directory hierarchies. New file systems can be created using vmkfstools -C.
