I found myself in the same situation: X520 card (intel 82599 based) on unRAID server and microtik CRS305-1G-4S+IN switch, 10Gtek transceivers at both end. The ping was solid, but the link was going down very briefly every few seconds. For some reason the Microtik switch came with RouterOS enabled. Since I did not need the router funcionality, I thought I rebooted to the switch OS. Just like that, the flapping on the X520 link is gone. I just checked, and the link did not go down once overnight. Maybe just a coincidence, not sure, as always YMMV, but I thought I mentioned it. Transceivers are 10Gtek AXS85-192-M3, and the PCIe the card is also from 10Gtek, model X520-10G-1S-X8.

Yesterday I finally completed moving the data from the drives to be removed to the drives that were staying. The server is now rebuilding parity on the new config; the array was shrunk from 22 to 13 drives (plus parity plus cache). unRAID rocks.

I do take a screenshot of the drives, from time to time, which has helped, over the years. Thank you to FreeMan and itimpi for helping me.

@FreeMan So parity is the only disk I need to worry about in keeping the array integrity, that's going to make the whole process a lot easier. I don't believe I have any per-disk exclusions, but I'll double check. The server does have hot-swap cages, but don't mind stopping the array first to avoid any potential issues. @itimpi That's even better, thanks! Wow, unRAID very smart

I'm planning to reduce the amount of data currently stored on my unraid server. This is what I was thinking, please correct any flaws: 1. remove a disk from the existing array 2. stop the array 3. upon starting the array, the removed disk shows up as "missing" 4. run tools / new config (keeping existing parity disk) 5. start array / run parity-sync 6. if parity-sync successful, rinse and repeat In step 4. when I re-assign the disks to the array, does it matter they are in the same slots as before, and do I need to respect any gaps (i.e. if disk 15 was unassigned before, does it still need to be unassigned in the new config?)

I am planning on removing one of the smallest HDs (disk6) from the array, once the change from RFS to XFS is completed. To this end I kept disk6 as the last disk to get copied. Is the best way to accomplish removing a drive, short of rebuilding parity (stop the array, un-assign the drive, then run tools / new config)? Should I delete all data from disk6 before un-assigning. would that make any difference?

Right, I should have figured that out. 3 disks done (out of 11), one in progress. I'm averaging 36 MB/s with the copying so far.

disk21 is included in the folder share and something is writing to the share. I don't understand. The source drive is disk2. Shouldn't anything on disk2 have ended up on /mnt/disk21/t ? Now that cp is done, I can access /mnt/disk21/folder from Windows, all the files appear to be there. Do you think I can move everything to the root of disk21?

I've started moving my backup server to XFS, following to the letter bjp999's instructions on the first page. I'm on step 7, and the first disk is being copied to the destination, and I noticed something odd. While most of the file are getting copied to the t folder, a few very recent files (along with new files that are being created) are going to a separate folder on the root: /mnt/disk21/t/ <most of the files are going here> /mnt/disk21/folder <a few recent files are going here> folder is a hidden share Also odd, a /mnt/disk21/t/folder has been created, but Windows tells me I have no rights to access it when I try to browse the content. Any ideas?

Thanks. I just wish that the PSU had longer motherboard and CPU power wires. Luca
