Transfer data from ReadyNas duo v1 hdds

[tcdk]

Hi

I am setting up an Truenas system with 4x3TB SAS drives on an M5015 raid controller.

I have data on my old ReadyNas duo v1(2x2TB XRAID) with around 1.5TB data total. The network controller in the ReadyNas are buggy, and will max transfer with UP to 1-2mb/s which will result in around 3 months transfer time.. And most times I start to transfer data, the ReadyNas lock up and I can't access the admin panel.
Since it's XRAID, I can remove 1 hdd from the ReadyNas without data loss.

How can I transfer my data to the Truenas system, without Truenas nukes the drive? Would it be possible via the motherboards SATA and if the filesystem can not be read, eg. via an VM on the Truenas?

Stop right there, and start over.

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...

It sounds from a brief Googling that XRAID is just some variant on mdadm, so you can quite possibly just hook the drives up to a PC and then transfer it to TrueNAS, either over the network or directly.

Thanks.

I will see if I can find a M1015 instead of the M5015 to run IT mode.

That'll work. It may also give you enough ports on the mainboard to hook up your ReadyNAS drives to see if they can be mounted.

Yes. The M1015 supports up to 16 drives, so it's more than enough. I just got the M5015 thrown at me, that's why I wanted to use it.

The M1015 only has eight lanes by default. You need an SAS expander to get beyond 8 drives.

8 is still plenty. I have cables for 8 drives (4 sas and 4 sata) andare not planinng on using more than 4-6 drives atm anyway.
