Guidelines
Use the read-only command to specify the mount type as read-only. This setting
allows only file read operations on NFS mounts. By default, NFS mounts can read
transactions and write transactions.
retrans
Specifies the maximum number of RPC minor time outs to allow before the
transaction fails.
Syntax
retrans count
Parameters

Guidelines
Used in conjunction with the timeo command to specify behavior in response to
RPC minor time outs and subsequent retransmission attempts.
The retrans command specifies the number of RPC minor time outs that are
tolerated per NFS transaction before an NFS read or write error is declared. The
timeo command provides a base value to determine the interval between the RPC
time out and the subsequent retransmission attempt.
For example, assuming default values (3 for retrans, and 0.7 seconds for timeo),
RPC time outs are dealt with as follows.
1. In response to the first RPC time out, the appliance waits 0.7 seconds and then
2. In response to the second RPC time out, the appliance doubles the initial time
3. In response to the third RPC time out, the appliance doubles the previously
4. In response to the fourth time out, which is greater than the value specified by
The interval between RPC time outs and a subsequent retransmission will never
exceed 6 seconds.
