aacraid: slow write on raid
December 31, 2011 09:36AM
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.
