Current Hardware:

 

HP DL380 G6 2x Xeon 5670

72GB RAM

7x 5TB Seagate Barracudas

1x 1TB SSD

 

Previous RAID Card:

Integrated HP 410i

 

New RAID Card:

LSI MegaRaid 9265-8i

 

unRAID Version: 6.5.1 (also downgraded and tried 6.5.0)

 

After configuring the drives via the LSI Megaraid configuration utility I booted into unRAID, created a new config, mapped the drives to the same order as configured with previous raid card, and starte the array.

 

While the Cache Drive was able to mount the array itself is showing the following:

 

Unmountable: Unsupported partition layout

Not sure how to fix the issue. I have connected the drives back to the old RAID card and that seems to work again just fine (albeit terrible performance, hence the reason for replacing the card).

 

What can I do without having to format the drives.

 

Some output that may help:

 

root@Tower:~# sfdisk -l /dev/sdg

Partition 1 does not start on physical sector boundary.

This is from one of the drives.

 

I found this article but not sure how to downgrade to 6.3.5 exactly. Would this even help me?

You shouldn't add disk in controller's RAID mode, all disks should run in single disk. It may need flash the controller in HBA (IT mode)

 

And don't know why data disk seems normal, but cache drive was a 1TB disk and not in AF (advance format 4K/sector)
