If you have it mapped to /mnt/user yes, that's why it's usually recommended to use /mnt/cache for nextcloud. Won't be needed anymore as long as the share is exclusive.

True. All my dockers is mapped in /mnt/user/appdata/*

Quick question.

 

I have 4 disk in the array I want to do a zfs mirror pool with 2 of them and keep the other 2 drives for other shares.

 

Should I create the zfs pool in the array section or in the pool section of unRAID webui?

 

If I create the zfs in the array I guess I should move the other 2 disk to the pool section as single disks, right?

Or can I keep them in the array?

 

Just for info as pools I have 2 nvme for docker and vm working as single disks.

 

What is the best approach to avoid conflicts in the future?

My server is down until I get an answer

Array is still individual disks not pools. Each array disk can be a separate zfs disk but not a pool.

 

 

 

Ok, so the zfs should go to the pool and the 2 single disk that I have in the array I guess it would make sense to move the to pool section as single disk as well to be able to use the exclusive mode, right?

One more Issue, Mover Task runs forever. All Hdd´s are already spun down again, but Mover Task runs still doing nothing.

 

It is not moving system from the array to the pool, docker and vm is disabled in settings.

as for lz4 vs zstd, there's no better. Depending on what you are putting on the pool and if you have enough CPU to compress, zstd is great.
Most of my workload are huge files (100GB+) but some of those files have plenty of 0's inside (sometimes 50%).
So I can save a lot of disk space my letting ZFS compress and the more I compress more I save disk space.

zstd vs gz is different, zstd is faster with a marginal compression loss.

As for the other part, right now I manually set the pool compression to zstd, however everytime I start the pool (aka server reboot or start/stop array) it comes back to lz4. Not that a big issue as I don't restart my server that often.

Keep the great work guys! Amazing product! I'm starting to build the second sever and it will be another Unraid Pro! 

 

How can I see what compression is used? I can only see compression=on, not the algorithm used.

 

Edit:

Never used ZFS before and usually wait for stable Unraid releases but I really like the changes so I went for it. Have switched my cache pool (2xSSD) from btrfs to zfs mirror now and everything just works (right now) and looks great. Great work and thanks to the team!

unRAID 6.12-rc4.2
Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03)
Randomly looses Internet connection.

 

My main unRAID with Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 (rev 01) works normal. Same connection (Switch / Router)

Sometime in the future, might shares on array disks, that have been confined to one disk (via Included Disks) be considered as Exclusive, and be bind-mounted.

Since RC4(1) my server looses internet connection after a few minutes of runtime. While VMs are still running, most docker containers and especially the server itself aren't able to connect anymore. If you connect using ssh it's possible to ping outside or resolve domains.

 

My diagnostics are attached.

Is it easy to roll back to v6.11.5 if rc4 is not working right? or just wait for stable version - Thanks

..But it does not format the drives after a few seconds the unraid site refreshes and the 2 ssd´s are still not formated.

I can check the format field again and start formating but nothing happens.

Unlikely that this is related to the rc release, so please start a new thread in the general support forum and post the diagnostics after a failed format attempt.

how can i make SNapshots? Do i need one of the ZFS Plugins for that or is there already something in the Gui i dont see?

Would be nice to see them on the explorer in Windows so i can rollback there.

 

tried the ZFS Master Plugin now..

and i have a lot of Snapshots on System, but i didnt do that..

Considered that, but writes to unraid array disks are greatly throttled by r/m/w parity updates.  Maybe would benefit reads, but you can enable 'disk shares' and get the same benefit.

On mine, I noticed at first it showed "compression=on" on the tooltip info flyout that you get when you hover over the dataset (in ZFS Master), but after a little bit it will populate with the compression type. Screenshot:

 

 

Separate message to keep the quote chain clean. Running 6.12.0-rc4.1, and reconfigured for ZFS. I configured everything on Saturday and then today I noticed all of my shares had vanished, datasets are still there. 

 

For my setup, I have a dummy USB drive attached to the array, since I couldn't start it without one (I just assume that's a work-in-progress workflow). Using ZFS Master plugin to manage the ZFS Pool side of things. I imagine all of this is heavy work-in-progress and subject to change as things get built out.

 

It appears the flashdrive I attached to the array died (for the record, it's very old, and I did move all data points off of it so it wouldn't see writes), which kept the array up but the shares disappeared. I noticed this when I rebooted and couldn't restart the array nor mount that particular flash drive. So that'd be something I hope changes as things evolve -- ability to start the server ("array") without an attached drive to the Array side of things, since I'm doing only ZFS pools.

 

Attaching diagnostics anyways, if it helps anything.

The Tools>New Configuration option doesn't seem to work to reset just the array configuration.

 

I have an USB flash that I was just using as a stub for a nonexistent array with the all data on a zpool under the old zfs plugin. Now that I can create shares on the pool and use it directly, I no longer need the single usb flash "array." If I try to use new config preserving only the pool device, the single slot array is still preserved and I can't remove it. No shares are set to use the array and it's actually completely empty.

Quick question on exclusive shares. Right now, for a cache=only share, we have /mnt/user/share shfs path and /mnt/poolname direct mount. Most docker templates come with shfs path configured, but I have changed many of those to direct mount for better performance

 

Am I correct to understand that the new exclusive share feature will turn /mnt/user/share to be a direct mount? Will the other path still be available? Does the user need to make any path adjustments or will the upgrade do something about it?

Yes.  It's a bind mount.

With v6.12 you still need to have at least one data device assigned to the array. 

another issue with zfs on my pool.

every few seconds i have writes to the nvme zfs pool (mirror). No VM or Docker is running.

 

No random writes to my zfs hdd on the array.

it was. im testing right now without it. (since 1 hour no more writes)

But why should there be any random writes (no reads at all) if no VM and Docker is running?

 

edit:

@trurl

still getting random writes, a lot less but still.

OK, thanks. I only see "on" there but as I understand it default/on is LZ4 for OpenZFS since a couple of years. 

I was wondering (sorry, if this was answered before) will there be user intervention required to successfully switch from array/cache to primary/secondary storage? Or does the upgrade work without problems automatically?

I had no problems. Everything worked as before. No config changes, only how the gui presents the information.

i know with the new version in RC4 updating the dashboard.. is there anyway to shrink down the windows like before? like i don't need to see ALL 20 cores i just want to see general CPU usage.. same with Memory usage and other items as well..
