HP-UX Reference (11i v2 07/12) - 1M System Administration Commands N-Z (vol 4)

nfsd(1M) nfsd(1M)

The following command:

/usr/sbin/biod 16

will result in a total of 16 block I/O daemons being launched. The number of active CPU’s in the system

has no effect on the number of

biod daemons started.

WARNINGS

When the

biod daemons are not running and the buffer cache is exhausted, I/O on NFS loopback ﬁle sys-

tems might block indeﬁnitely under rare circumstances, leading to application hangs. To avoid such a prob-

lem, it is recommended to use direct I/O on these NFS mounts (see mount_nfs(1M)).
