Trying to mount 13 Tb disk on RedHat system.

[Margaret Doll]

We are trying to use a 13 Tb disk on one of the latest RedHat system;  
namely, 2.6.18-128.4.1.el5xen.

"ext3" cannot see beyond 2 Tb.

We understand that zfs can work with the 13 Tb disk.  However, zfs  
does not come with RedHat.  Can it
easily be added to a RedHat system.  How?  We will need complete  
instructions if this is possible.

What are the drawbacks to using ZFS?

Thanks.
