Slow parity and crashing with E350 motherboard

Featured Replies

Hi Guys,

 

I've got a GA-E350N-USB3 with a AOC-SASLP-MV8 card for 12 total drives. I know it's a new motherboard (I believe Linux drivers aren't available in the kernel version that 5.0b6a uses) but it seems to only sort of work.

 

Syslog:

Problems:

1. Will crash randomly during a big network send if I send it over wireless (LAN cable is fine, makes no sense to me!)

2. Parity creation is down around the 300kB/s mark, even after a couple of days of letting it run

 

Also all my drives are pretty new (EARS) and I didn't preclear them but they're formatted and sitting happy now - does it matter?

 

Ideas?

 

Edit: Seems that the LAN issue is a common problem - refer here. Still doesn't explain the slow parity.

There are plenty of mvsas error reports out there with 2.6.36. Some kind of status issue where the driver has to time out before continuing, resulting in horrible performance. I do think some here are using those cards with 5.0b6a though.

Thanks Cyrnel. I'm having trouble picking up any words on a possible fix - do I need to sit tight and wait for a new driver?

 

 

dgaschk - I can't get a SMART report. It just outputs:

 

Device Read Identity Failed (not an ATA/ATAPI device)

A mandatory SMART command failed: exiting.

 

SMART is turned on in the BIOS, and there's no option to enable/disable SMART in the Supermicro controller menu.
