Occasional slow writes to cache, stop and start of the array fixes.

[dabone]

I'm running a ASRock E3C226D2I motherboard with a Xeon 1240v3 cpu and 16gb Ram.

The drives are 4 4tb + 1 Tb cache.

 

When everything is running fine, I'm getting around 65-70 MB per second writes.

But sometimes it slows down to under 1MB per second. All write are done to the cache drive.

 

Stopping the array and then restarting it brings back full speed.

 

Any suggestions?

 

Thanks.

Perhaps a network problem. Try writing to an array drive directly and see what speeds you get.

No network issues.

Like I said, it will give 1mb write speeds sometimes, and doing NOTHING else, except stopping and starting the array puts the speed back up to 60-70MBs.

 

No server reboots, no switch reset, no network changes. But restarting the copy yields full speed again.

 

It looks alot like problems mentioned a while ago.
