Drive(s) Read/Write error since switch from unraid.

[MrYoshii]

My System:

• Motherboard: Gigabyte B760 Gaming X AX DDR4
• CPU: Intel Core I5 13500
• RAM: Corsair Vengeance LPX 32GB (2 x 16 GB) DDR4 3200MHz
• Hard drives, quantity, model numbers, and RAID configuration, including boot drives:
  4x ST8000DMZ04 1x ST8000VNZ04 RAIDZ1
• Hard disk controllers: Adaptec ASR-72405
• Network cards: onboard from MB

The Problem:
On the weekend, i moved from Unraid to Truenas Scale. I put all my data from my Backup back on the Array.
Overnight i did a Scrub Tasks.
In the morning, I saw a few massages via Telegram:
And this was the array status:

The one drive with no errors was the missing one.

After that, i did a restart of the system. The drive was back online and the System did a resilver.
That one drive did still have errors so i removed it from the array and checked with smart. Looks ok to me so i quick format the drive and put it back in. It resilvers again but the drive(s) still gets errors?

Not sure whats up with that in unraid i did not have any problems with the drives?

There are two things that could cause your problems:

1. Your Adaptec Card only has an HBA mode, not a real IT mode.
2. You're using SMR drives which are known to cause problems with zfs.

SMR drives are known to cause problems with zfs.
If you haven't used the zfs plugin on unraid then you've propably used xfs or btrfs which work better with SMR drives

1. Your Adaptec Card only has an HBA mode, not a real IT mode.

Yes im useing HBA mode why is that a problem?

2. You're using SMR drives which are known to cause problems with zfs.

Uhh damn ok that's unfortunate.

What's all the noise about HBAs, and why can't I use a RAID controller?

1) An HBA is a Host Bus Adapter. This is a controller that allows SAS and SATA devices to be attached to, and communicate directly with, a server. RAID controllers typically aggregate several disks into a Virtual Disk abstraction of some sort...

here's a resource from this forum explaining why hba-mode and HBA Card are not the same

Ahh, ok, since I can see smart and the drive's real names, I think the controller is not the problem.

 

[jgreco]

I think the controller is not the problem.

@LarsR is correct. Let me be a little clearer for you: THE CONTROLLER IS THE PROBLEM. ADAPTEC'S "HBA MODE" IS NOT COMPATIBLE WITH TRUENAS.

 

[MrYoshii]

@LarsR is correct. Let me be a little clearer for you: THE CONTROLLER IS THE PROBLEM. ADAPTEC'S "HBA MODE" IS NOT COMPATIBLE WITH TRUENAS.

okok what controller should i buy?
If got a 24Bay inter-tech 4U-4424 (SFF-8643)

 

[jgreco]

I'd throw an SAS expander in there and then an LSI 9300-8i as the HBA. I recommend researching any 12G SAS expander prior to purchase; my memory suggests there was one that is strongly disrecommended but my memory isn't being particularly helpful today as to which one. If you are unfamiliar with SAS expanders, please see the SAS Primer posted in the Resources section.

In the future, it's probably better not to get an off-brand chassis. What you really want is to have an SAS backplane with an SAS expander built-in, which is an option simply not available with many of the off-brands. If you had a nice Supermicro CSE-846BE1C or 847BE1C, for example, you'd just need to connect one or two SFF-8643 cables to the chassis backplane(s) and call it a day. It makes everything shockingly easy.

 

[MrYoshii]

Ok, thanks for the info.
With zpool status -v i found two corrupted trash files on the array. I deleted them did a restart and did a scrub again, now it seems to be fine. Also, I changed the Controller mode from HBA to RAID RAW. Is there a way to check if this fixes the issue?
