The created file displays an entry for disks located by the /usr/cvfs/
bin/cvlabel

 command.

CvfsDisk_UNKNOWN /dev/sdb # host 4 lun 1 sectors 639570752 ...
CvfsDisk_UNKNOWN /dev/sdc # host 4 lun 2 sectors 639570752 ...
CvfsDisk_UNKNOWN /dev/sdd # host 4 lun 3 sectors 639570752 ...

In the /usr/cvfs/config/cvlabels file, delete any lines that refer to disks 

that will not be labeled or have already been labeled.

Edit /usr/cvfs/config/cvlabels file to provide a unique name for each 

drive to be used by SNFS. 
In this example, the UNKNOWN variable in the drive name 

associated with disk device /dev/sdb has been renamed to a numeral 

(in sequence) 0,1,and 2. The disk devices have also been 

alphabetically ordered.

CvfsDisk0 /dev/sdb # host 4 lun 1 sectors 639570752 ...
CvfsDisk1 /dev/sdc # host 4 lun 2 sectors 639570752 ...
CvfsDisk2 /dev/sdd # host 4 lun 3 sectors 639570752 ...

Save the /usr/cvfs/config/cvlabels file. 

Use the cvlabel command to label the disks. Type:

/usr/cvfs/bin/cvlabel /usr/cvfs/config/cvlabels

For each disk, you are prompted to verify that you want to label each 

disk. Type Y for yes.

Modifying Global Settings

The global section of the file system configuration file contains general 

parameters that control enabling and disabling features, system 

performance, and components related to the file system’s resource 

consumption. 

Identify any drives that already contain a 

recognized Volume Type. Do not write a label to 

these drives or you may lose data.
