Continous Disk Errors Unraid 6.8.3

[erichner]

Running Qbittorrent causes massive file errors that normally knocks off 1 parity and 1 data drive offline. Rebuilds required to get back online.

 

I've replaced the parity drive that I thought was in question and recently added a new one that is now suffering from these disk errors, regardless of the SATA port.

 

I usually have these running simultaneously without error in the past:

Plex

Qbittorrent

Radarr

Radarr4k (same but for 4K)

RadarrSync

Sonar

Jackett

Lidarr

Krusader

Both fail disk should be false error ( connect to 9230 ), pls avoid use Marvell controllar.

Any suggestions on a LSI card that can do SATA/SAS and support 16 drives (up to 16tb) and won’t break the bank?

 

Any idea of how much of a performance increase a 6GBps vs a 12GBps card would make?

 

I have (9) 3.5in drives + (2) cache SSDs + (1) SSD for VM.

 

Does it make sense to use the Marvell controller only for drives that are not in the array and for specific VMs? This would be for the use of unassigned drives will not be consistently pushed as they are now with seeding/uploading torrents in Qbittorrent (and causing the disk errors).

LSI 9201-16i ( PCIe 2.x, not support SSD ) or 9305-16i ( PCIe 3.x , limited support SSD ), you won't have performance increase from 6Gbps to 12Gbps.

LSI 9300-16i should be avoid ( Power draw 27w )

 

Suggest 9305-16i due to natively PCIe3.x, concern 9201-16i would run in PCIe 1.x instead PCIe 2.x , like your GTX 1050 Ti was PCIe 3.x but run in PCIe 1.x currently.

All negative.

The 1050 runs in PCIe 1x due to an converter / extension I used to mount the card upside down. Wasn't due to the actual motherboard.

I don't have any experience with SAS HBA boards, so please excuse my ignorance.

 

Would any of these work that are closer to my budget of $200 or less:

 

LSI SAS9750-16I4E 16 Port Internal 4 Port External 6Gb/s PCI SATA+SAS
https://www.ebay.com/itm/LSI-SAS9750-16I4E-16-Port-Internal-4-Port-External-6Gb-s-PCI-SATA-SAS/372880810737?hash=item56d16da2f1%3Ag%3AsEsAAOSwbTVd-nha&LH_BO=1

 

LSI Megaraid SAS 9260-16I SAS 512MB Controller L3-25243-20D W/ BATTERY & CABLES

https://www.ebay.com/itm/LSI-Megaraid-SAS-9260-16I-SAS-512MB-Controller-L3-25243-20D-W-BATTERY-CABLES/254427115539?hash=item3b3d09b013%3Ag%3AaIMAAOSwk5Fd1EMy&LH_BO=1

 

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

 

Would this one be better than the 9305-16i if I was going to spend $300:

 

Broadcom LSI SAS 9400-16i (05-50008-00) 12Gb 16 Port HBA - New Sealed Box

9400-16i also fine and it support NVMe, but this won't have performance gain in your case too.

 

There are many different kind LSI card, not all work with Unraid.

 

In fact, most pepople with go with 8i card i.e. 9211 or 9207, because it cheaper a lot. You could connect SSD to mainboard.

I wish I could do the 8i but I have 9 HDD drives. Also, my NVMe drive is mounted to board directly for a bare metal VM, so no worry there.

 

I figure with the 9305-16i or 9400-16i I can get one or two dual SSD 2.5in drive to 3.5in HDD adapters and put in another one or two of my extra drives as well.

 

Thanks for all the info!

Would something like this work?

 

i like the idea of it coming with cables and supporting 24 drives when I upgrade in the future.

If need connect 24 disks, most people would go to HBA + SAS expander route, i.e. a 4U rack cass with expander blackplane or standalone expander. Of course, you can do that by multiple HBA or some high port count HBA etc.
