NFS Management
13
The
nfs
command manages NFS clients and displays NFS statistics and status. See “nfs” on
page 232 for the complete command syntax.
A restorer exports the directories
/ddvar
and
/backup
.
/ddvar
contains restorer log files and
core files. Add clients from which you will administer the restorer to
/ddvar
.
/backup
is the target for data from your backup servers. The data is compressed before being
stored. Add backup servers as clients to
/backup
. If you choose to add a client to
/backup
and
to
/ddvar
, consider adding the client as read-only to
/backup
to guard against accidental
deletions of data.
Add NFS Clients
To add NFS clients that can access the restorer, use the
nfs add export client-list
nfs-options
operation. Add clients for administrative access to
/ddvar
. Add clients for
backup operations to
/backup
. A client added to a subdirectory under
/backup
has access only
to that subdirectory. The client-list can have a comma, a space, or both between list entries. To give
access to all clients, the client-list can be an asterisk (*).
nfs add {/ddvar | /backup[/ subdir ]} client-list [ (nfs-options) ]
The
client-list
can contain IP addresses, hostnames, or wildcard hostnames, such as
*.yourcompany.com
.
The
nfs-options
list can have a comma, a space, or both between entries. The default NFS
options for an NFS client are: rw, no_root_squash, no_all_squash, and secure. The list accepts the
following options:
ro Read only permission.
rw Read and write permissions.
root_squash Map requests from uid/gid 0 to the anonymous uid/gid.
no_root_squash Turn off root squashing.
all_squash Map all user requests to the anonymous uid/gid.
no_all_squash Turn off the mapping of all user requests to the anonymous uid/gid.
