Great work, thanks guys!

Ah yes, I meant to say 6. Thank you johnnie.black!

Hi, I'm currently using unRAID on a tower but since I'm running out of room for new drives, I'm looking around for a proper server chassis. I found a 4U 24 bay chassis from Logic Case, which has a backplane with 6x SFF-8087 Mini SAS connectors. I currently have 2 Dell Perc H310s (IT flashed) which I'm about to utilise for this new server, I need a third one in order to connect the remaining drives. My question is: do I only need 3 SFF-8087 to SFF-8087 cables to connect the HBAs to the backplane or is anything else needed? My mainboard has enough slots to support 3 HBAs.

Thanks, that did the trick.. mostly. Unfortunately, Plex didn't play ball but I think I'll be able to salvage it. Thanks again for your assistance.

Thanks for your quick response. I was able to run btrfs restore and copy all the data to one of the disks (the process stopped a few times due to looping, but I retried each time and eventually finished copying the data). I attempted to run a btrfs check --repair, but this failed. Is it safe to format the disk now using the btrfs fs, and copy the data again? Should I consider replacing this SSD just in case?

I'm running out of disk drives in my current case, so I added an HBA in my unraid server (LSI 9201-16e) and added a single drive in my DAS connected to the unraid machine. I had to switch the card with my main HBA (Dell Perc H310) since the drive wouldn't be detected, but I succesfully added the new disk to my array. Ever since this has taken place, I've been unable to mount the SSD in my unraid server. This SSD contains the docker image. I've tried to mount it manually (it's set to auto mount) but it throws up this error: Jul 22 10:41:46 unRAID2 unassigned.devices: Mounting 'Auto Mount' Devices... Jul 22 10:41:46 unRAID2 unassigned.devices: Adding disk '/dev/sdn1'...

Nice work, thanks guys.

If this kind of stuff is new to you I do suggest to try and read through this thread. I've flashed several cards and also have posted a link to download the files you may need. It was specifically for the Dell Perc H310 card so you will need to make sure that your MegaRAID card uses the same chipset. Did you get the download package from this thread? Yes, I grabbed LSI SAS2008 Controllers(P10)Linux.zip which was referenced in the beginning of the thread. According to https://forums.servethehome.com/index.php?threads/lsi-raid-controller-and-hba-complete-listing-plus-oem-models.599/, the LSI 9265-8i uses the SAS2208 chipset. I saw various references to the Dell Perc H310, but these are all related to the LSI 2008 chipset - would this be compatible with the 2008? I'm not sure to which post you're referring - would it be https://lime-technology.com/forum/index.php?topic=12767.msg409244#msg409244 by any chance? Thanks!

Hello, I currently own a MegaRAID SAS 9265-8i adapter with 8 drives attached which I want to utilise for unRAID. I came across this thread and various others, and learned I need to flash my adapter to IT mode so I download the file package for the SAS2208 adapters and saved the ZIP contents on the unRAID USB drive. I made sure to remove the existing array and also installed the latest firmware, but when I ran the first shell script (1_ListAllAdaptors.sh) it returned the following error: Array found STARTED, stop array before proceeding How do I fix this? Thanks.
