PCNFS_SERVER [0 | 1]
Used to enable or disable the pcnfsd daemon by
/sbin/init.d/nfs.server
.
START_MOUNTD [0 | 1]
Used to enable or disable the rpc.mountd daemon by
/sbin/init.d/nfs.server
.
NUM_NFSD [number]
Number of NFS deamons (nfsd) to start on an NFS server. The default is 16. This vari-
able will be obsolete in a future release.
NUM_NFSIOD [number]
Number of NFS BIO daemons (biod
) to start on an NFS client. The default is 16. This
variable will be obsolete in a future release.
The
setoncenv command recognizes the following kernel tunable variable names for the NFS subsystem
(a complete description of all NFS kernel tunable variables can be found in the Managing NFS and KRPC
Kernel Configurations in HP-UX 11i v2 white paper at http://docs.hp.com):
nfs2_do_symlink_cache
Used to enable or disable the symbolic link cache for NFS version 2 mounted file systems.
nfs2_dynamic
Used to enable or disable dynamic retransmission for NFS version 2 mounted file systems.
nfs2_shrinkreaddir
Limit the size of a READDIR request to be no greater than 1024 bytes of directory informa-
tion.
nfs3_do_readdirplus
Control the ability to turn off the NFS version 3 readdirplus functionality on the NFS
server.
nfs3_do_symlink_cache
Used to enable or disable the symbolic link cache for NFS version 3 mounted file systems.
nfs3_dynamic
Used to enable or disable dynamic retransmission for NFS version 3 mounted file systems.
nfs3_jukebox_delay
Controls the length of time the NFS version 3 client waits before re-transmitting a request
after receiving the error [NFS3ERR_JUKEBOX].
nfs3_max_transfer_size
Controls the size of the data portion of an NFS version 3 READ, WRITE, READDIR, or
READDIRPLUS request.
nfs3_max_transfer_size_clts
Controls the size of the data portion of an NFS version 3 READ, WRITE, READDIR, or
READDIRPLUS request over UDP.
nfs3_max_transfer_size_cots
Controls the size of the data portion of an NFS version 3 READ, WRITE, READDIR, or
READDIRPLUS request over TCP.
nfs_nrnode
Controls the size of the rnode cache on the NFS version 2 and version 3 client.
nfs_async_read_avoidance_enabled
Enables users to configure their NFS clients to allow applications to send NFS READ calls
on their own behalf, when all the biods are busy. This tunable will be obsolete in a future
release.
nfs_clnt_avoid_write_copy
An unnecessary copy of data to XDR buffers impacts the write performance of NFS. Ena-
bling the nfs_clnt_avoid_write_copy tunable avoids this copy and improves the
write performance of NFS. This tunable will be obsolete in a future release.
nfs_do_purge_rddir_cache
Controls how an NFS client manages the readdir cache contents. This tunable will be
obsolete in a future release.
