aacraid: slow write on raid [Solved]

Postby coudy » Sat Dec 31, 2011 15:46

Hello, I have Adaptec 24610 conntroller (HP 6 port adapter) with 4x 500GB hdd in RAID10 .
I have slow write 20-40MB/s. I have tried many distros, kernels and options. I have 3 cards with Debian 6 and 1x with Sabayon. All are 64 bit. I have enabled write-cache on all drives and all raids, but still slow write. I have tried options aacraid cache=0/1/2, write is still slow.
When I try write benchmark from Live CD I get 100MB/s write. But on formatted system it is only 20-40MB/s
Could you please help me ?

I can post lspci, lshw, arcconf output if anyone want it.

If no one else posts here, it's probably because your question is very specific. If you don't get any other replies, I suggest that you post your question on Adaptec's Linux Blog as they seem to be very helpful, and you would get an answer from an Adaptec expert.

Link to Submit question isn't working (http://response.adaptec.com/forms/LinuxQuestions)
Do you know other working link ?

It's easy enough to find another page on that site to submit your question: http://ask.adaptec.com/Scripts/adaptec_ ... .php?&5=19. But first see my post in your other thread: Re: can't see loaded module in lsmod.
