If you want to mount it permanently put an entry in “/etc/fstab” file like any other filesystem. Now your VxFS filesystem is mounted and you can start using it. # df -h /data # mkdir ~]# mount -t vxfs /dev/vx/dsk/testdg/testvol ~]# df -hP /dataįilesystem Size Used Avail Use% Mounted on # mount -t vxfs /dev/vx/dsk/testdg/testvol /data Now create a directory to mount the filesystem. For mounting purpose block device is used.Ħ. Note: /dev/vx/rdsk/testdg/testvol is a character or RAW device and for mounting we don’t use it. # mkfs -t vxfs ~]# mkfs -t vxfs /dev/vx/rdsk/testdg/testvolĢ04800 sectors, 102400 blocks of size 1024, log size 1024 blocks Now, once the volume is created, format it as a VxFS filesystem using the below command.

Mounting VxFS Filesystem in Red Hat Enterprise 7 (RHEL 7)ĥ. The above command will create a volume with the name “testvol” having size 100 MB. Once DG is created with one disk, create a volume as below.

If the DM name is not given while creating the disk group, then by default disk name will be used.Ĥ. Testdg01 is a logical name called DM name (Disk media name). # vxdg init testdg ~]# vxdg init testdg ~]# vxdg list To create a disk group (DG) with one disk use below command. No complex layouts in this tutorial like Stripe, Mirror, Mirror-Concat, etc.ģ. Here we are using a single disk to create a DG and a Volume. Once the disk is initialized and is under control of VxVm, we can create a Disk Group (DG). # vxdisksetup -i ~]# vxdisksetup -i ~]# vxdisk -o alldgs list |grep -i emc_d2īy default CDSDISK (Cross-Platform Data Sharing Disk) type is used and can be changed as per requirement. Once the disks are visible to the VxVM, initialize the disk which are not under VxVM control, i.e. # vxdisk -o alldgs ~]# vxdisk -o alldgs listĢ. First of all, check the disks which are visible to Veritas Volume Manager (VxVM) and this can be done by “ vxdisk” command as below.
