[Lustre-discuss] More newbie issues

Greetings.  I managed to work around the problem I was having with

by moving from RHEL 5.2 on a v20z to RHEL 4.6 on Thumper, ran into a 
different problem which appears to be a deal breaker for me.  I forcibly 
failed one of the drives in the raid-1 mirror for the MDT and the file 
system promptly stopped responding to clients.  The rest of the machine 
worked just fine.  A reboot of both the client + server cleared the 
problem.  Its looking like Solaris/ZFS might be a better answer for me.

Thank you for the advice.
