Displaying details of a replicated file system

You can view the disk composition of a non-replicated and replicated file system by using the list command.

Before you begin

To perform this task, you must be a Db2® cluster services administrator.

Figure 1. Single-site IBM Storage Scale replication topology

Procedure

Run the following command to list the details of file system db2datafs in figure 1:

db2cluster -cfs -list -filesystem db2datafs

  PATH ON LOCAL HOST      OTHER KNOWN PATHS        NSD NAME       RDNCY_GRP_ID      COMMENT          STATE    SIZE    FREE
  --------------------   -------------------    --------------    ------------      -----------      -------  ------  	------
  /dev/hdisk2               -                         nsd2              1           DIRECT ATTACHED     Up    15.0GB  10.0GB
  /dev/hdisk5               -                         nsd5              2           DIRECT ATTACHED     Up    15.0GB  10.0GB
  /dev/hdisk8               -                         nsd8              -           FSTIEBREAKER        Up    100.0MB  0.0B

Note:

With replicated file system, all devices in redundancy groups 1 and 2 are accessible by the host as indicated by "DIRECT ATTACHED" under the comment column.
The free size of the file system tiebreaker disk is 0 because that disk is not used to store user data or metadata. Therefore, it is not counted as usable space.
