Hello, i use a combination of different array disks all check out well with smart self testing.

As parity drives i use 2  18TB Seagate Exos drives - both checked out fine during the pre clear run.

The SATA/SAS Conrtoller is from LSI - SAS2116.

here is some of its specs :

---------------------

    <node id="storage" claimed="true" class="storage" handle="PCI:0000:01:00.0">
         <description>Serial Attached SCSI controller</description>
         <product>SAS2116 PCI-Express Fusion-MPT SAS-2 [Meteor]</product>
         <vendor>Broadcom / LSI</vendor>
         <physid>0</physid>
         <businfo>pci@0000:01:00.0</businfo>
         <logicalname>scsi1</logicalname>
         <version>02</version>
         <width units="bits">64</width>
         <clock units="Hz">33000000</clock>
         <configuration>
          <setting id="driver" value="mpt3sas" />
          <setting id="latency" value="0" />
         </configuration>
         <capabilities>

---------------------

Are there any issues known with that drive/controller combination ?

Are there any HDD tune or controller or global tweaks that might help ?

i will preaclear the both Parity drives once again so you can take your time (about 48 to 60 hours)

with any answers or solutions.

Feel fre to asl for any log or diagnostic files - and please tell me where to find them.

Make sure the LSI is using the latest firmware, if needed you can use Unraid to update it.

Maybe I missed it, but you don't seem to say what the problem actually is. As in, any description of the actual problem itself.
