Thank you, let me know if you need further diagnostic

I wouldn't even for home solutions. There are problems to sort, I bought 2 Pro and 1 Basic licenses but I'm putting them down for now, passing to TrueNAS and Synology/Qnap in new purchases. I tought Unraid'd have been a good solution to re-use old hardware or even to build new NASes because internet communities are pointing at it as the best thing in the world. After trying it out (maybe because I'm used to professional devices) the feeling is that there is too much work to be carried out before this project worth current prices.

I got the right output: 147621332 /mnt/disk1/TheHub/Truenas4/./filename.mp4 976276944 /mnt/disk1/TheHub/Truenas4/./filename.mp4 3409636407 /mnt/disk1/TheHub/Truenas4/./filename.mp4 209565299 /mnt/disk1/TheHub/Truenas4/./filename.mp4 272780277 /mnt/disk1/TheHub/Truenas4/./filename.mp4 320218609 /mnt/disk1/TheHub/Truenas4/./filename.mp4 172232382 /mnt/disk1/TheHub/Truenas4/./filename.mp4 Then I also got folders which dimension is 6

Unfortunately same behaviour. I proceeded moving manually those files, meanwhile, a disk failed, so now I am trying to move the entire content of disk 6 (12TB) to disks 11 and 12 (8 TB + 8TB) and I'm getting the same problem. It stays a while "checking issues" then the usual 1 byte transfer. Is there some logging that would be useful to you? In this case: "The following items will not be transferred, because there's not enough space in the target disks" But I'm trying to copy 11.86TB in 15+ TB drives:

$RECYCLE.BIN is empty and not expanded, selected files belongs to "Truenas4" directory and I can't select it because it's something like 12TB while I need to transfer aroung 30GB. Tried also copying files from the bottom (names starts with "z") and same behaviour

Sure, i set it to verbose, but i don't see anything useful: logounbalanced SCATTERGATHERHISTORYSETTINGSLOG 2024/03/20 08:18:16 2024/03/20 08:18:16 ========================================================= 2024/03/20 08:18:16 disk(/mnt/disk4):no-items:currentFree(51.09 GB) 2024/03/20 08:18:16 --------------------------------------------------------- 2024/03/20 08:18:16 --------------------------------------------------------- 2024/03/20 08:18:16 2024/03/20 08:18:16 ========================================================= 2024/03/20 08:18:16 disk(/mnt/disk5):no-items:currentFree(50.99 GB) 2024/03/20 08:18:16 --------------------------------------------------------- 2024/03/20 08:18:16 --------------------------------------------------------- (cut) 2024/03/20 08:18:16 ========================================================= 2024/03/20 08:18:16 Bytes To Transfer: 1.00 B 2024/03/20 08:18:16 --------------------------------------------------------- As you can see, it say "Bytes To Transfer: 1.00 B", then the rest looks ok Then: Here you can see history: Settings I choose:

Hello guys, I'm trying to use unbalanced to free up some space on my disk1, however after selecting files and destination disk it only transfer 1 byte and say everything is done, while it's not. I tried many times, and in one case it transferred files, in the others no. What am I doing wrong?

I was looking at the dashboard plugin. Now it makes sense and perfectly explain performance drop after 200GB! Finally I have clear ideas on what's happening on Unraid

I have the opposite problem: I was expecting to see all ram used, instead of that only 4GB out of 256 are used. Do I missed some options?

Even if RAM is always shown < 4GB used? Good to know, at least all that RAM is useful!

ZFS Zpools may have redundancy? (ex. RAID Z1) If not, once finished transfer i can setup a zfs pool with a replica task for most used files

Does the 1% apply also for bigger array? I have 382 TB now, an plan to go to 500TB with final disk... That mean I'd need 5 TB RAM... Also, i rolled back from ZFS to XFS because of slowliness

Got that. So it makes sense, now I'm writing as low as 60 MB/s when I'm near the end of the disk (so 180 MB/s) and 90 MB/s when in faster zone. Also there was some kind of problem with the other machine, and it died today. I replaced mobo/cpu/ram at once (no time to investigate, data transfer is long enough) and it seem more stable now, acting as expected. Building the new one I'll try to put only new and equal disks, so it will make sense keeping turbo write on and transfer @ full speed! Another quick question 1 : does having 256GB of RAM makes sense? I've never seen more than 4GB used. (Note it will never run containers nor VMs as there's a separate cluster for that). Question 2: How many free space is it best to leave in disks?

That's why I'm not understanding low speed: parity drives are the faster one (min. 150 MB/s) and I'm moving big video files, so why I'm not going at full speed? And, above all, why first hundred of GB go at full speed? Maybe there's some thermal trottling involved (all temperatures seem low)? Or some caching issues?

I'm not getting this: - Before: 28 disks (actual ones + smaller and slower disks which have never been used) - Now: 28 disks (removed some small and slow disks and replaced with 18TB/280MB/s drives) - Having turbo write off, I'm only using 3 disk at a time. Parity disks have always been 2 x 18 TB Exos drives. May the overall array size be the culprit? I'm gonna build a twin machine, and I'd like to avoid bottlenecks...
