So, I'm building my first server here and have been testing out my Asus A7V880 with a couple of 300GB Seagate drives and an old 80GB Seagate. I have had the one 300GB data drive on an internal SATA port (the mb has two) and the parity one on a Promise S150 TX4 and was getting 35-40 MB/s parity check speed.

 

Now I have replaced the parity drive with a Hitachi 2TB drive (intending to replace the 80GB drive next with one more Hitachi 2TB). But Parity check speed has dropped to 10MB/s. This is going to take a bit more than 2 days aparently. On top of that I found that the internal SATA controller does not recognice the Hitachi 2TB drives so I can not move the parity drive to the internal SATA controller.

 

Any advice wellcome. This server with the A7V880 is meant to be a stop-over solution until I can upgrade my desktop and move it's Gigabyte P35-DSR3 with 6+2 SATA ports over to the unraid server. But I had hoped for better speed than 10MB/s on the intermin one here.

Advice #1.  Post a copy of your syslog

Advice #2.  Investigate if a BIOS upgrade of your MB is available to be able to deal with the larger drives.

Sounds like good advice. Will I need it to complete the parity check before extracting that syslog ?

no, do it now, while the parity check is under way.

When I got home I found the parity check had ended after only ~12 hours. Seems speed was just slow in the beginning, possibly while the 80GB disk was involved (although it did not cause this problem before the parity disk was upgraded to the 2TB disk).

 

So things are looking up, I am now restoring the data from the 80GB to the other 2TB disk from the array and it is running at 50MB/s - which I think is more than I could have hoped for with the two big disks on a PCI controller.

 

This is neat stuff, I'm totally loving it
