Creating a Dynamic (Shared) Volume

Creating a Shared Volume from the Command Line

Create a shared volume on the CVM master. In this example, the volume is 20 MB in size:

# vxassist -g cfsdg make vol1 20M

Activate the shared disk group for shared write access on all nodes:

# vxdg -g cfsdg set activation=sw

Then check the configuration:

# vxprint

TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0

v vol1 fsgen ENABLED 40960 - ACTIVE - -

pl vol1-01 vol1 ENABLED 41760 - ACTIVE - -

sd cfsdg vol1-01 ENABLED 41760 0---

Creating a Cluster File System from the Command Line

On any cluster node, create a file system on the shared storage volume:

# mkfs -F vxfs /dev/vx/rdsk/cfsdg/vol1

If you do not specify size, the complete volume is used for the file system.

Mounting a Cluster File System in Shared Mode from the Command

Line

To mount the file system on all nodes in the cluster, enter.

# cfsmntadm add cfsdg vol1 /mnt all=rw

# cfsmount /mnt

See the cfsmount(1M) and cfsmntadm(1M) for information on adding and mounting a

shared file system.
