Write speed starts off fine at 115 MB/s then after about 10 seconds drops off to 1-3 MB/s.  I have reset router and upgraded firmware on router, rebooted and upgraded server to 6.1.6, I have tried copy files from other computer on same network with same issue.  All wired.  Please help.

 

v 6.1.6

plugins: open files, dynamix webgui, unraid server os

hardware core I5-2400

Could someone at least take a look at my logs to see if anything dosent look right?

If it starts at 115MB/s for 10secs it suggests to me that the network is working ok, the speed is good while Unraid is caching to RAM and degrades when full.

 

Don’t see anything obvious in your log, but disk 1 has a very high UDMA_CRC_Error_Count of 84366, keep an eye on this and if it keeps rising change SATA cable.

 

The low speed you mention is the same copying to the cache disk or to a disk share?

 

 

I tested writing to each of my disks with the same result.    I will change out my sata cable on the parity drive for sure.  If it seems likely my parity drive is going out should I just replace it?

 

 

Thank you for looking into this.

Disk1 is not your parity drive.

Yes the parity drive seems fine, the CRC errors are on disk1, but if you can write to the cache disk with normal speeds and slow to all others disks maybe consider changing parity drive or disabling it temporarily, make sure you have backups.

I temperately disabled the parity drive and have the same result.  Any other suggestions?
