I decided to take another look at this with v7.2-rc1 and openzfs v2.3.4 to see if any of the latest improvements happened to alleviate this problem. TL;DR statfs() for zfs behind fuse is 15-20x slower than anything other filesystem, even with mitigations. I first attempted to recreate the scenario in the OP as-is with just the updated tooling. There was zero changes and I saw the exact same performance degradation. The problem seems to occur when statfs is used by rtorrent to get properties like free disk space. I was able to somewhat solve the problem by removing the eliminating the free space property the exists on every torrent so it wouldn't be requested for every xmlrpc query, but there were still statfs calls being made periodically. Since I'm pretty sure that is the issue I decided to see if I could just demonstrate the degradation with minimal additional context. On a new share with just generated directories and files here is the average time for a statfs call to take in different scenarios: ZFS - Exclusive Share (4 drive mirror w/ nvme special vdev) Total elapsed time: 179.99 ms (0.18 seconds) Successful calls: 1000 Failed calls: 0 statfs() timing breakdown: Min time: 0.153 ms Max time: 0.248 ms Avg time: 0.180 ms Total statfs() time: 179.85 ms Overhead (non-statfs): 0.14 ms (0.1%) Array Only (28 mixed HDDs) Total elapsed time: 585.95 ms (0.59 seconds) Successful calls: 1000 Failed calls: 0 statfs() timing breakdown: Min time: 0.372 ms Max time: 1.166 ms Avg time: 0.586 ms Total statfs() time: 585.84 ms Overhead (non-statfs): 0.10 ms (0.0%) Array + ZFS (Primary: Above ZFS pool, Secondary: Above array) Total elapsed time: 9387.06 ms (9.39 seconds) Successful calls: 1000 Failed calls: 0 statfs() timing breakdown: Min time: 9.045 ms Max time: 12.728 ms Avg time: 9.387 ms Total statfs() time: 9386.79 ms Overhead (non-statfs): 0.28 ms (0.0%) It doesn't matter if the files are on the array, or the cache, or even if the dataset is not yet even created. It didn't matter how many settings I changed or tuned. Every single time there is that much of a hit just having any zfs pool on a non-exclusive share. And I tested many time again with using the same devices formatted as btrfs and the performance almost always was the same as the array only tests. I also tested this on a more modern system and it just shift all the numbers upwards with the same relative degradation. 0.159ms avg for array only and ~3.5 ms avg for array + zfs. To me this seems much more extreme than just fuse overhead + zfs overhead. For now I am just going to have to move ahead with a different pool topology than I would have liked.

Just to tell the story of what I am encountering, visually. This is how I can dynamically recreate this problem. Note: Neither cache or temp pools have any files for the software share. Not even the folder. Everything is on the Array currently. But now when I swap the temp (btfrs) pool with the cache (zfs) pool: This result is reflected immediately after swapping the pools and it makes no difference if I restart the container or the entire machine. I'll see if I can replicate this performance drop in a container but outside of rtorrent and then see if that also can be replicated outside of docker.
-
I can confirm that a container mapped to an exclusive share on my mirror ZFS pool is extremely fast and responding in <200ms with 1000 torrents. There is definitely a weird interaction happening with zfs behind fuse, and it's not inherent to zfs (which I didn't expect anyway).
-
This doesn't happen when it's just the array (27 drives) or when the nvme cache drive as primary is formatted as btrfs. As soon as that same cache drive is formatted to zfs, the performance tanks, with no other changes.

I've been plagued this issue in both 6.12 and 7.0.0-beta.1/2 and I have finally narrowed down the exact configuration cause. In all of my instances of this docker container, I am mapping the root of one of my shares (R/W). Normally, the list action on the webui will take 700-1000ms to respond back but it's been take 10+ seconds and it's when any ZFS pool is configured to be the primary storage with the array being secondary. Here is the results of some configurations for this share that I've tried, where-in it's the ONLY change that is made: Primary: Array, Secondary: None - 700-1000ms response time Primary: single 2TB NVME encrypted btrfs, Secondary: Array - 700-1000ms response time Primary: single 2TB NVME encrypted zfs, Secondary: Array - 6000-8000ms response time Primary: 3x 2-Mirror 10TB encrypted zfs, Secondary: Array - 10000-12000 response time I have done testing with the cachedirs plugin and it does not affect these outcomes at all. I originally thought this was the cause because my zfs pool wasn't named "cache" at the time and the plugin only seems to cache /mnt/disk* and /mnt/cache, but later renaming the pool had zero effect. Now this is also when the zfs cache/primary drive is completely empty, it still affects the performance. I also tried with direct_io turned on and it had zero effect (though I didn't expect it to). I am going to be setting up a container to test whether this also occurs with the zfs pool as an exclusive share or if this is entirely cause by zfs behind fuse. I couldn't find any similar issues so I don't know if this is just extremely specific to whatever rtorrent is doing. I'd like to determine what exact command(s) are taking so long to return back when the share is configured this way, but that would be a whole other deep dive to get some proper profiling on the process because the debug logs didn't give me any useful information. ecba-diagnostics-20240715-1508.zip

I just upgraded to 7.0.0-beta.1 from 6.12.10. I am adding a new 6 drive ZFS pool so I wanted to do it with the latest version. Upon configuring and letting it go to format, it fails on the format and put the disk in an error state. These 6 drives were all previously working fine in the Array (as XFS Encrypted) and replaced with larger drive only in the last week. I tried a couple more times and with a 4 drive BTRFS mirror instead and received the same (or similar) errors. After multiple reboots I tried the drives individually with with XFS, ZFS - encrypted, and BTRFS - encrypted and it's the same story, so it's independent of the filesystem it seems. I then tried a SATA drive and it works totally fine... Log from formatting one of the SAS drives (via UD plugin): Jul 9 15:08:46 ecba unassigned.devices: Format device '/dev/sdg'.

I may downgrade back just to make sure it does work. Any assistance would be appreciated. Also there are no SMART errors on these drives before or after. The only other thing I do is enable write caching on these drives via user script (at array start), but this happens whether or not that has run. ecba-diagnostics-20240709-1532.zip

You have too much memory. But seriously I too have 128GB and encounter similar issues and I believe the only fix is to adjust the write caching to ram. I have been searching this issue for weeks and lots of people have similar issues and the only resolution seems to be the following: Download the tips and tweaks plugin and adjust down the vm.dirty_ratio and vm.dirty_background_ratio values. Or set those values yourself from the command line. I need to do some more indepth testing but I currently have mine set to 4 and 2. I haven't fully tested if it fixes my specific symptoms when running the mover since I have undertaken other migitations to resolve them but I do know I am seeing similar I/O waits with the new values too. If you want to find previous topics search for 'io wait' or 'dirty_ratio' but here is the one in particular that led me to this fix:
-
In my ideal world it would work how I initially thought zpool and zfs worked. I love the concept of vdevs and in that context it makes total sense why drives need to be the same. Before further reading I thought with redundancy happening at that level, then you could freely mix and match different vdev topologies in a zpool to combine them together. Not only can you not (or at least it's very much not recommended), but I came to realize that losing one vdev loses all of the data. That freaks me out. I think it would be great to have a pool that can stripe files across many vdevs, then you could control at the share level where data can be will be placed. For example, if you had an array consisting of a 6-wide RAID-Z2 and 4-wide RAID-Z1 you could mark the 'photos' share to only or prefer the Z2, but 'media' could go anywhere similar to how we have include/exclude disk options.

I am assuming the write cache checking is done using hdparm. Would it be possible to use smartctl instead so that SAS drives can also be checked? Not sure what the equivalent sdparm command is, if there even is one, but this one below works for both SATA and SAS drives. smartctl -g wcache /dev/... I had run into write issues for the last couple of days and I finally narrowed it down to only 3 out of my 6 SAS drives have writeback cache enabled by default. I had no idea. Simple add to my write cache enabling script but I just assumed they were all enabled by default if it wasn't reported by this plugin. From the man page for smartctl: -g NAME, --get=NAME, -s NAME[,VALUE], --set=NAME[,VALUE] wcache[,on|off] - [ATA] Gets/sets the volatile write cache fea- ture (if supported). The write cache is usually enabled by de- fault. wcache[,on|off] - [SCSI] Gets/sets the 'Write Cache Enable' (WCE) bit (if supported). The write cache is usually enabled by default.

I am encountering this problem and I feel like it's only just started happening today. The SMB share from my unraid box is mounted to a linux machine connected over a 2.5GBe link. As soon as I invoke the mover it totally distrupts that mount. Doing a simple list just hangs indefinitely. If I stop the mover and wait ~5 minutes it becomes responsive again. I just switched the mount to nfs4 (which I wanted to do anyway) and I am not experiencing these same issues. EDIT: Nevermind it's happening with the NFS shares as well. A little while after turning off the mover it magically comes back to life.

In one of those threads I linked someone tried without plugins and it still happened. I never bothered to verify so I can't say either way for sure but it would honestly make the most sense if it were the ZFS Master or some other plugin.
-
That may have been my comment. The TL;DR I came away with was that it was temporary files being written to these disks and that it was not coming from any plugin (maybe). I didn't want to deal with it so I reformatted them, but yes in the few days that I them in the array they never spun down. It was very tiny writes happening every 10-15 seconds on each of the ZFS disks in the array. Here is some further discussions of the same issues I experienced:
-
I went back and forth on this when adding 5 new drives to my existing btrfs formatted array. I decided to try zfs because it's a more mature file system, even if it's new to unraid, hoping to eventually convert the entire array down the road. Now I wish I had stuck with btrfs. There is already other topics for it but there is problems with slow write speeds and constant read/write activity only on zfs disks inside of an array. Seems to be still undetermined on the root causes. You are right that btrfs has scrubbing, snapshotting and compression just like zfs. I am probably going to stick with only using zfs for pool devices going forward.
