My life is generally Mac and Thunderbolt centric and I’m trying to bring it into the Linux world. The work flow on the Mac goes immediate storage goes onto a 2TB external NVME, then to one of the two drive 4TB drives on my OWC open dock, then moves into a 16TB soft RAID array, and backup is on a 16TB HW raid all are thunderbolt enclosures. The issue I have is that mdam doesn’t work on either my Trixie or 26.04 install so I can’t convert my existing soft RAID to anything readable.
Does anyone know of a 8 bay preferably thunderbolt hardware RAID enclosure that isnt’t 1000 dollars?
The main issue is statefullness of the host.
Say you’re on a laptop, and you get an external JBOD box without any hosted controller. You use that laptop to setup a RAID1 array on 2 disks, and go about your business. Few weeks in you’re in the middle of some editing of video or whatever, and you have a power outage.
That RAID array is assuredly damaged or dead. Your host machine being the controller in the middle of a write when the entire array dissapears is going to give up quickly, and the cached data in flux to write is gone. You miiight be able to recover the array if you’re lucky, but whatever you’re working on is gone.
A number of diff5scenariis where this may happen exist without a power outage, but the problem is the target not being able to manage its own interrupt, and you have two different states in two different devices that won’t match. It’s toast.
