Chapter 8: Configure MxFS-Linux 164

NFS Clients

After MxFS-Linux is configured, your NFS clients can begin accessing the

exported PSFS filesystems.

Timeout Configuration

It is recommended that NFS clients have a minimum timeout value of 120

seconds. NFS failovers typically take much less time, but in a worst-case

scenario may approach 120 seconds.

Client Mounts

To access the shared data on PSFS filesystems, clients simply mount the

exported PSFS filesystems.

# mkdir /mnt/data1

# mount -t nfs 99.10.210.100:/mnt/psfs/nfsdata1 /mnt/data1

The following command verifies that clients on the 99.10.210.100 network

can now access the shared data:

# ls -l /mnt/data1

total 1

drwxr-xr-x 2 root root 48 Mar 24 00:32 dir1/

-rw-r--r-- 1 root root 0 Mar 24 00:32 file1

-rw-r--r-- 1 root root 0 Mar 26 12:29 file2

-rw-r--r-- 1 root root 0 Mar 24 00:32 file3

Client Mount Options

Soft and hard mounts can be characterized by how they handle errors.

• Hard: When an NFS client with a hard-mounted share requests a file,

it keeps trying until either it succeeds or someone interrupts its

attempts. You can use the intr and nointr options to specify whether

you want users to be able to interrupt an NFS request.

• Soft: When an NFS client with a soft-mounted share requests a file, it

tries to receive the file a specified number of times (retrans) and each

try waits for a specified amount of time (timeo). After this, if the file

has not been received, NFS will return an I/O error to the process on

the client machine requesting the file.
