When we were trying to do DW stuff on Linux + Opteron + FibreChannel + EMC DiskArray, we too frequently found filesystems keeling over. It was neither cheap nor reliable.
When is When? Not trying to start a flame war but I am curious as to your specifications to make this stuff work. Was it kernel 2.4 or 2.6?
It 2.6, which? What filesystem are we talking about? Are we talking the last 12 months? Or earlier then that? Sincerely, Joshua D.
