My server is showing tons of /dev/SDA errors. Failing sectors etc. It's still running right now. Is there an easy ti back up my system before I reboot and reinstall? I have backups of my files and stuff on the array. My USB backup is rather old though .

When you added 16 4tb drives I'm guessing you had them on the same controller so hitting all drives at once like parity does will slow it down. The controller becomes a bottleneck at that point basically. 8 drives didn't max it out but 24 sure will. I'd recommend either adding a 2nd HBA, going with a HBA that has the bandwidth to support 24 drives at full speed, or moving some drives to SATA ports to lower the bandwidth hit. I'm sure you've already resolved your issue but wanted to add this for anyone who stumbles on this in the future. You could also simply live with it too. It's not often every drive is active simultaneously in my experience. Mainly during parity operations. Writing and reading from a few drives at once won't show any slowdowns until you have enough going to use all the available bandwidth on the bus or card.

I would love to replace my original Lime-Tech Badge on my server! I'll try and post pics later if anybody is interested.

Welcome! I have been using Unraid for almost 2 years now and have been amazed with its features and reliability. I can't comment on your synology questions, but allow me to touch on the drives. You can add your 2xSSD's as cache. The 6TB drives can be added to the array, so long as the largest drive is parity. If you have the 6tb drives, and a bunch of smaller drives, one of the 6tb ones would be dedicated to parity. You can choose not to run parity, but in my opinion that removes one of Unraid's best features, data protection. Keep in mind if you choose to add the 6tb drives or the SSD's, they will most likely need formatting. Please be sure to transfer all the data off them to be safe first. What did you mean about combining the debian server into Unraid exactly? Transferring the CPU and RAM over? That should work just fine if the sockets and memory are compatible. I've upgraded my Server many times, even changing sockets from a dual core to a quad core, and finally to a dual socket Xeon build. Unraid always picked up where it left off at and never complained about the hardware change. Again, welcome to Unraid and the forums. If you have any other questions don't hesitate to ask. I've found the people here are always willing to help, and quite a few are very knowledgeable.
