Slow Disk Speed after replacing a disk?

[Stanui]

Hello all, Im was hoping to get some help diagnosing very slow (10-25MB/s) data rebuild speeds on my system after I replaced a drive that failed last week. 

 

In the disk logs I see I have the following errors on couple of my drives.

I have some new SATA cables and a new SAS/SATA PCIE card coming hopefully this weekend as that was the only thing I have not tried replacing from my SATA PCIE expansion card.

 

 

Any suggestions or Ideas would be greatly appreciated! Thank you!

The Marvell controller has or is connected to a SATA port multiplier, those should be avoid, Marvell controllers by itself should also be avoided.

Thanks for the reply, I had taken a Marvell 9215 SATA expander from a previous system when building my unraid server and haven’t noticed issues until rebuilding the array… 

 

will swapping to an LSI LSI00301 SAS/sata card be the solution? Or would you recommend another part?

 

thank you

Thanks! I have a 9207 8i coming hopefully this weekend, fingers crossed system holds together until then. Thank you for the replies.
