C
OMMANDS
The no command option resets the value of a given option. For example, no protocol
nfs default server policy resets the policy to the default value.
Syntax [no] protocol nfs default server {direntrymap <cr> |
policy [custom | global_rw | home_dir] |
read-ahead [small-files <cr> | transfer-size <size>] |
read-dir [optimize <cr> | read-size <size>] |
threshold multiple <multiple> |
write [optimize <cr> | max-data <max>]}
Parameters
Example
minna (config) # protocol nfs default server read-dir optimize
minna (config) #
minna (config) # protocol nfs default server write optimize
minna (config) #
protocol nfs default volume
Description Configures default settings for the NFS volumes.
The no command option resets the value of a given option.
direntrymap <cr> Enables the directory entry map.
policy [custom | global_rw | home_dir] Specifies one of the following policies:
• Custom. Enables you to turn on or off the root
squash feature for NFS volumes from this
server.
• Global Read-Write. Specifies a policy that
provides a trade-off of performance for data
consistency. All of the data can be accessed
from any client, including LAN based NFS
clients (which do not go through the HP EFS
WAN Accelerators) and clients using other
file protocols like CIFS. This option severely
restricts the optimizations that can be applied
without introducing consistency problems.
This is the default configuration.
• Home Directory. Specifies all accesses to
each directory are by a single user. This policy
allows aggressive caching of data and
metadata.
read-ahead [small-files <cr> |transfer-
size <size>]
Enables read-ahead for small files; sets the
transfer size in bytes.
read-dir [optimize <cr> | read-size
<size>]
Enables read optimization for the directory; sets
the read size in bytes.
threshold multiple <multiple> Specifies the threshold multiple.
write [optimize <cr> | max-data <max> Enables write optimization for the directory;
sets the maximum write size in bytes.
