Retrieving file system information

You can use the db2cluster command to obtain information about file systems and the disks that comprise each file system.

The db2cluster command provides an easy way of finding out more information about:
The file systems managed by Db2® cluster services
To list the file systems, use this db2cluster command: 
db2cluster -cfs -list -filesystem
An example of the output from this command:
FILE SYSTEM NAME                       MOUNT_POINT
---------------------------------      -------------------------
prodgpfs4                             /prodgpfs4
The disks that are used by a file system
To list the disks, issue the db2cluster command: 
db2cluster -list -filesystem filesystem-name -disk
For example, for a file system called prodgpfs4, you use this command: 
db2cluster -list -filesystem prodgpfs4 -disk
An example of the output from this command: 
PATH ON LOCAL HOST                      OTHER KNOWN PATHS
---------------------------------      -------------------------
    /dev/dm-0
    /dev/dm-1
    /dev/dm-2
    /dev/dm-3
    /dev/dm-4

PATH ON LOCAL HOST might vary from host to host. An asterisk beside a disk indicates that the disk is a tie-breaker disk. It cannot be removed from the file system unless another disk is assigned as the tiebreaker.

OTHER KNOWN PATHS shows if a disk appears with a different device path name on another host.

The configuration of a file system
To list the configuration of a file system, issue this db2cluster command: 
db2cluster -cfs -list -filesystem filesystem-name -configuration
For example, for a file system called prodgpfs4, you issue this command: 
db2cluster -cfs -list -filesystem prodgpfs4 -configuration
An example of the output from this command: 
prodgpfs4
