Please let me know if there is anything wrong with this planned setup. 

No personal experience with your proposed combo, but this thread seems to indicate you should be good to go.

The OP used a different card and disk shelf, but others chimed in on the thread, some with plain LSI cards and the model you posted, so it looks good to me.

THANK YOU Again!

If the shelf comes with SAS interposers remove them, they are not needed and SMART won't work correctly with them.

[Ctek]

Sorry, I have 2 more question: 

Planning on taking ALL 23 hdd's (except cache) drives off SATA/Enclosure/USB and stick them in this shelf. 

So the Parity drive will be in the shelf instead of SATA.

 

Wanted to make sure this makes sense and gives me the best transfer speed possible?

Also, will I have trouble with the 5 drives labeled JMicron?  Is there something I need to run before I move those drives? 

 

Please let me know if you need more info.

 

Thanks again for your guidance and advice!

Looking forward to the shelf install next week

Never used a NetApp shelf, but I believe they are single link, if so better performance would be with as many disks as possible in the current case, this would affect mostly parity checks and rebuilds, unless you use turbo write.

You'll need to do a new config for Unraid to accept the name change.

Gotcha, so leave the drives connected to the SATA controller in PC case and just move over USB stuff to the shelf.

THANK YOU!

Shelf installed and I have 12 drives installed and 11 drives going to a SATA controller or mobo sata. 

I have everything off (dockers/smb/vms) and I wanted to make sure I have everything setup for the fastest rebuild speed.

I noticed the speeds are jumping and I see red errors in the log like:  kernel: ata4.01: exception Emask 0x100 SAct 0x0 SErr 0x0 action 0x6 frozen.

I've attached the diag file, please let me know if you have any questions.

 

Thanks!

Those are from the SATA port multiplier connected to disks 1, 2 and 12, that Marvell controller uses one for some of the ports, leave disk2 there for now and move disks 1 and 12 to the enclosure, ideally you'd replace that controller with a recommended non Marvell one, or just move all those drives to the enclosure, but performance might not be the best.

[Ctek]

Oh Wow, the speed is much better now after moving those 2 drives that you suggested to the shelf!

 

Do you happen to have a link to the approved  non - Marvell controllers for unraid?

 

Thank you!

Replaced SATA controller with the recommended one but now my server randomly crashes with no errors in the logs

I've attached my diags for review.

 

Thanks

See here first, if that was already done or it doesn't help enable the syslog server and post that after a crash.

[Ctek]

I turned the CPU down to 3.6 GHz from 4.7 GHz (chip default) and ram to 2666.  Seems to be holding now.

What is the max suggested CPU speed I can run? 

[JorgeB]

Use the default settings, without overclocking, should be stable at those speeds, also check that "power supply idle control" is set like it should in the link above.

[Ctek]

Got it, thanks again for your help!
