I am new to Solaris. I have Sun X2100 with 2 x 80G harddisks (run as email server, run tomcat, jboss and postgresql) and want to run as mirror to secure the data. Since ZFS cannot be used as a root file system , does that mean I am no way can benefit from using ZFS? Instead, I should stick with SVM? Otherwise, what is my plan?

This will include the zfs boot bits, so that you can use zfs as your root filesystem. --Tim -------------- next part -------------- An HTML attachment was scrubbed...

This last one is used as that machines zdev for its ZFS pool. So, root and swap mirrored using SVM, and everything else on a mirrored ZFS pool.

Did you do anything specific with the drive caches? How is your ZFS performance? Nathan. :) Rich Teer wrote:> On Wed, 19 Mar 2008, Terence Ng wrote: > >> I am new to Solaris.
