Hi, it's me again. First of all, technically slicing the drive worked like it should.
I started to experiment and found some issues I don't really understand. My base playground setup: - Intel D945GCLF2, 2GB ram, Opensolaris from EON - 2 Sata Seagates 500GB A normal zpool of the two drives to get a TB of space. Now I added a 1 TB USB drive (I sliced it to have 500GB partitions). I attached them to the Sata drives to mirror them. Worked great... But, suddenly the throughput dropped from around 15MB/s to 300KB/s. After detaching the USB drives it went back to 15MB/s. My Question: Is it possible that mixing USB 2.0 external drives and Sata drives isn't a good idea or is the problem that I sliced the external drive? After removing the USB drive I done a little benchmarking as I was curious how well the Intel system works at all. I wonder if this 'iostat' output is okay (For me it doesn't) sumpf 804G 124G 257 0 32.0M 0 sumpf 804G 124G 0 0 0 0 sumpf 804G 124G 178 0 22.2M 0 sumpf 804G 124G 78 0 9.85M 0 sumpf 804G 124G 0 0 0 0 sumpf 804G 124G 257 0 32.0M 0 sumpf 804G 124G 0 0 0 0 sumpf 804G 124G 0 0 0 0 sumpf 804G 124G 257 0 32.0M 0 sumpf 804G 124G 0 0 0 0 sumpf 804G 124G 257 0 32.0M 0 sumpf 804G 124G 0 0 0 0 Why are there so many 0 in this chart? No wonder I only get 15MB/s max... Thanks for helping a Solaris beginner. Your help is very appreciated.
