Multiple GuardPoint Pathnames

If you have multiple LDT hosts guarding and sharing the same LDT GuardPoint directory with different local pathnames, the pathname that will be associated with LDT operations is the pathname used on the LDT host designated with primary status.

When you are entering voradmin ldt commands, you must use the primary host's local pathname for the GuardPoint when you specify the GuardPoint parameter. If another host is promoted to the primary status for the GuardPoint, and the GuardPoint directory pathname is different from the pathname on the previous primary host, then LDT changes the the pathname of the GuardPoint to the pathname of the new primary host.

For example, let's say you have two hosts (LDT_Host_1 and LDT_Host_2) with the same directory in an NFS share mounted on different mount points on each host, and subsequently, you must enter the new primary host's local pathname for the GuardPoint:

• GuardPoint on LDT_Host_1: /nfs-oxf-fs1-host1/gp

• GuardPoint on LDT_Host_2: /nfs-oxf-fs1-host2/gp

When the GuardPoint is first added to LDT_Host_1, that starts the initial data transformation:

secfsd -guard /nfs-oxf-fs1-host1/gp
secfsd: Guardpoint initialization in progress

MDS has the GuardPoint configured for rekey at /nfs-oxf-fs1-host1/gp.

voradmin ldt list all
MDS_1:  type=file, nguards=0, name=/nfs-oxf-fs1-host1/gp/__vorm_mds__
        Guard Table: version 1 nentries 1
        Guard 0: type=GP, state=REKEYING DIRTY, flags=GP LOCKED, gp=/nfs-oxf-fs1-host1/gp
                File List: count 4

When the GuardPoint is enabled on LDT_Host_2, the host joins the LDT GuardPoint Group for the GuardPoint.

secfsd -guard /nfs-oxf-fs1-host2/gp

secfsd: Path is guarded

Unguard the GuardPoint on LDT_Host_1 while rekey in progress:

Note

This operation triggers the promotion of LDT_Host_2 to primary status:

secfsd -unguard /nfs-oxf-fs1-host1/gp secfsd: Path is not guarded

On LDT_Host_2, guard the same directory mounted at the different path:

voradmin ldt list all

secfsd -guard /nfs-oxf-fs1-host2/gp
secfsd: Path is guarded

MDS now has the GuardPoint configured for rekey at /nfs-oxf-fs1-host2/gp on LDT_Host_2.

voradmin ldt list all
MDS_1:  type=file, nguards=0, name=/nfs-oxf-fs1-host2/gp/__vorm_mds__
        Guard Table: version 1 nentries 1
        Guard 0: type=GP, state=REKEYING SUSPENDED (qos), flags=GP LOCKED, gp=/nfs-oxf-fs1-host2/gp
                File List: count 4
