How to plan NFS installation?

59.How to plan NFS installation?
Ans.
1. User need to decide few things before start installing the Network file system and they are as follows:
• Decide the file system to export.
• Decide which users are permitted to mount the expected file system.
• Decide the schemes i.e. auto mounting or manual mounting that clients will use to access exported file system.
• Select naming convention and mounting scheme.

 2. Better NFS exports include any file system that is shared among a huge number of users, such as home, workgroup projects directories, shared data directories such as ‘/usr/share’, ‘/var/mail/spool’.

 3. Make use of ‘/home/username’ to mount home directories since most of home directories are accessed in similar way.

 4. If exported file grow large, so far this subdivision is necessary, which becomes tedious for administration , that when clients mounts, it should be updated to reflect new set of exports.

 5. Create logical volume set on NFS server, if it has large number of NFS mount for client.

 6. Use RAID and logical volumes for flexibility, for large sites, distribute multiple NFS exports across multiple disks so that a single disk failure will have less effect.

 7. User cannot export a file system that is itself already a NFS mount.

44.Explain process of setting up a NIC (Network interface card). Ans. 1. Network interface card (NIC) can be set-up by configuring the network card and internal network. 2. Before configuring network card we must check loopback (IP address 127.0.0.1) is working. 3. Even if the compute is not connected to outside network internet network configuration is required for some applications. This address is known as loopback device, and its IP address is 127.0.0.1 4. To check loopback device is configured or not, we use ‘ifconfig’ command it shows a device called ‘lo’ with the address 127.0.0.1, if this device and address is not shown there then loopback is not configured. 5. To configure it we can use command ifconfig lo 127.0.0.1 after that we need to use the ‘route’ command to give system a little more information about this interface for this ‘route add –net 127.0.0.0’ command is used, after this loopback is setup. 6. To configure a network card we will use ifconfig co...

How to configure Network file system (NFS) client?

By
68.How to configure Network file system (NFS) client? Ans. 1. To configure client, make sure that the portmapper, NFS file locking daemons statd & lockd, mount command are avaialbe. 2. NFS client needs the portmapper running in order to process and route RPC calls and returns from the server to the appropriate port and programs. 3. We can ensure portmapper is running or not by using following command: #service portmap status 4. If portmapper is not running then it’ll show us portmapper is stopped to start portmapper we’ll use following command: #service portmap start 5. Mounting can be done using following commands: For example we wants to mount /media from the server configured at the end then we’ll execute following commands: #mount –t nfs 192.168.166.5:/media /media 6. If user wish, he/she can specify client mount options using mounts arguments as; #mount –t nfs 192.168.166.5:/media /media -o resize=8292,wsize=8192, hard, nolock 7. Following are t...
