I'm trying to combine two H/W RAID5 arrays (6 disks each on a ICP-Vortex 8643RZN controller) into 1 device using LVM, with XFS as the filesystem. Unfortunately, I'm getting terrible read rates (I'm doing my own benchmarking, with 1 process creating files of about 400K each, and another process reading and deleting the files). Just an 'ls' in a directory with 1000 files takes forever. A stat+unlink call in perl takes 1sec. Are there any 'gotchas' with this sort of a setup? The RAID5 partitions themselves work pretty OK by themselves. The hardware: - dual Xeon 2.0GHz w/ 2GB memory - ICP Vortex 8643RZN card - 73GB Fuji 10KRPM disks, 14 of them on a controller. Any tips, pointers, etc. would be appreciated.
