Replaced Parity unable to assign?

I'm sorry to be so needy recently; I very rarely tinker with hardware but necessity arose. My parity drive was on its last spins and I decided to move the entire system to a new case. Everything went fine until it was time to replace the parity drive.

 

I previously had it in a RAID0 on an ARC 1222, 2x4tb drives for 8tb total. The only thing I did was swap the dying drives and pre-cleared for two rounds. I left the truncation off. Now, when I am able to select it as the parity drive and start the array, it acts like it is going to start and then stops and brings me back to the main screen to start the server again. It does the same thing when I assign it as a regular disk and start.

 

Leaving it unassigned I can start the array unprotected. What did I do wrong? I've attached my log from a fresh reboot and starting as a parity drive. Any assistance or insights someone can offer is greatly appreciated. Thank you!

Would initiating the "new config" do any harm? I knew I was in for a lengthy parity re-build but I certainly don't want to lose anything.

I tried it, it didn't work. I've started syncing everything with my offsite backup and will start over with this one.

 

Thank you for you help!

I'm guessing the problem is the invalid partition error after unRAID creates it:

Feb 12 11:17:37 Galactica emhttp: shcmd (55): sgdisk -o -a 64 -n 1:64:0 /dev/sdb |& logger
Feb 12 11:17:38 Galactica kernel: sdb: sdb1
Feb 12 11:17:38 Galactica root: Creating new GPT entries.
Feb 12 11:17:38 Galactica root: The operation has completed successfully.
Feb 12 11:17:38 Galactica emhttp: shcmd (56): udevadm settle
Feb 12 11:17:38 Galactica emhttp: invalid partition(s)

Post the output of:

sfdisk /dev/sdb

Check that parity it's still sdb, if not use current identifier.

Thank you for the reply. I'm currently pre-clearing all the discs. I moved everything off the server to start fresh.

I was poking around the forum and found Areca has an updated driver and indicated that v6.0 had native support (what I came from before upgrading). When I'm able to rebuild the kernel after the pre-clear I'll attempt the updated driver as well.

I've cleared all the drives and started fresh with 6.2.4 with the module from Areca's site for this version. I tried 6.3.2 but they module was an improper format. (Also tried without Areca's drivers on 6.3.2 following the below thread without success.

 

I set the display name to automatic, installed my pro key and assigned the parity and one drive. Same results as before. I have confirmed the parity drive is still assigned to sdb. 

 

Any guidance is greatly appreciated. Thank you!

In case it still maters the problem is that your Areca controller is using a 4kb logical sector

 

Feb 12 14:55:49 Galactica kernel: sd 1:0:0:0: [sdb] 1953508992 4096-byte logical blocks: (8.00 TB/7.28 TiB)

 

unRAID currently only supports 512byte sectors, don't know it that setting is configurable on the controller.
