Hello!
Situation: a dual opteron 9.2 server with SATA-RAID (3Ware - driver: 3w-9xxx) and a dual opteron 9.0 accessing the RAID with NFS. I'm moving data from the "client" (9.0) to the server with mv command. Load on client is nothing. Load on server is 2.5-3 and yet there is nothing running there; Top has nfsd process at the top with 1-2 % CPU. Computers are connected via Gigabit ethernet. Data transfer rate is very slow: 2.2Mb/s!
The problem is not at the client end as we had the same kind of results transferring data from another (RH) server to the new SuSE 9.2.
Installed kernel is 2.6.8-24.11 (default SMP-kernel from SuSE). The RAID driver is also from SuSE 9.2 (I could not find information about which.
Any ideas? Any pointers to check? We really do not have any idea what is slowing down the server?

Are you commited to that controller? Do you have the option of jumpering it to be simple sata controller(s) without using the raid portion, and then using software raid?
No, not easily. I have lot's of data there... BTW, I'm using LVM in between the RAID and the partitions - but that should not make any difference, right? -- Hugo.
