I have an HP ML150 G5 and I have set up a mirrored 1.5 tb drive array. I have been having trouble with Linux throwing the drive into read only mode when it is under aload (oracle backup). I think the issue has to do with slow performance on the drive. I ran dd to benchmark write performance and got this:
writing 10MB: 69MB/s
writing 100MB: 20MB/s
writing 1000MB: 12MB/s
My question is, is this normal for a Seagate Barracudda 7200.11 drive? And, is there anything I can to to tune this array? I am not a Linux guru. Just trying to feel my way through this. Thanks.
