I'm running 6.12.3. I have a bunch of 'OLD' (ex-array) 4TB drives I've reinstalled to my server that I wanted to use to have a play with a ZFS pool. Here they are before I start. Unformatted, no FS etc.

 

 

I created a pool (I have 3x other pools previously set up) and added the disks;

 

 

So far, so good. Now, I click the link 'Zfs_pool_a' beside the first disk. (note, I DID NOT capitalise that name, I was careful to ensure I named the pool all lower case)

 

I set up my file system type as ZFS and configured my settings; 

 

 

However, I cannot apply these settings. Note that the 'Apply' button remains stubbornly greyed out. In fact, it remains so regardless of what file system type I select. If I click 'Done' and start the array, it goes ahead and formats the pool BTRFS.

 

I must be missing something obvious here, but what? A procedure? A setting? A checkbox somewhere?

 

Pointers appreciated.

Try wipefs -a /dev/sdX on all disks before adding to zfs pool.

No joy. Didn't have an impact on the issue.

 

 

I also remade the pool without the underscore character in the name, and reduced the number of drives to 3. But still the Apply button on pool editing remains resolutely  disabled.

 

Folks

 

Really stuck here. In playing around with this, I find that I can neither set up & configure a new pool nor can I make any changes to existing pools while array is stopped as the APPLY button remains greyed out on the pool settings page.

 

Diagnostics attached.

This is very strange, don't remember seeing it before, if you create a new pool and assign one of those devices does apply work?

No.

If I create a new pool and add one or more devices, (any device) I cannot apply settings.

 

If I access an existing working pool, make a small change, still the apply button is disabled. 

 

Essentially, I cannot make or edit pools, unless I'm willing to accept default settings for a new pool 

Please try booting in safe mode and/or using a different browser.

Have to you tried to Erase and then Apply?

I can erase, but even after that the apply button remains disabled.

Im trying with both the built in GUI (monitor attached), as well as a remote connected Chrome browser. Same result in either case.

 

i tried booting safe mode but there are problems there. In GUI safe mode, the browser won’t load the UI. In GUI or standard mode, a remote browser won’t connect, and even ssh fails to connect with password problems.

 

I guess ive got to fix that problem before I can progress with my pools issue.

It's not a general issue, so likely something with your config, if nothing else you can always redo the flash drive to see if it helps.

So I wiped my USB and reinstalled UNRAID. Copied my config directory and the issue persisted. (could not get GUI in safe mode).

 

I then embarked on copying my config sub-folders and files one-at-a-time to see which one was the offender. A painstaking process of reboot after reboot.

 

And would you believe - it was the VERY LAST FILE - the VFIO config. ARRRGGGGHHHHHH!!

 

With a  fresh UNRAID install + all my config folder except VFIO, which I rebuilt, I was finally able to create the ZFS array. It's chugging away now doing some test transfers so I can evaluate performance, but it seems somewhat on a par with my main array. I'll use it for a secondary backup for now so I don't commit any files I don't have copies of elsewhere. 

 

Thanks for looking.
