Installing linux on a NAS device
 

I have a Linux server which is installed with RHEL 5.0 .

A NAS device make EMC is also in the network .

Kindly let me know if the following details can be done .

While installing linux ,is it possible to assign the /var and /home partitions to the NAS device and the rest of the partitions to the Linux server .

Also currently all the partitions are done in the Linux server ,is it possible to move the /home and /var partition to the NAS device or map the /home and /var partitions to the NAS device .

Any help in this regards is appreciated .

Very possible. Read about volume management in Linux.
You can mount the /var and /home via samba (CIFS) or via NFS

NAS volumes in linux
 

Thks ,but as per the storage enginner /home and /var cannot be monted on NAS ,since its under the / (root ) partition.

Also i think we cannot shift the default directiries of /home and /var

You do not mount with the existing /home and /var partition. You build those partitions and configure how you want at install time. That way you can achieve what you want. (I would be very stupid to suggest you can mount a filesystem on top of another mounted filesystem .. :) )

NAS -Linux
 

If i install the /home and ?var in the linux server ,say RHEL 5 ,then is it ok if i mount the volume created in the NAS device say /storage ,via fstab .

Do i need to write some scripts ,so that it automatically detects the NAS volume and mounts it at the startup ,os will only the entry in fstab suffice .
