I think first of all your Diagnostics would be great.

 

Can only speak for myself but RC4 and ZFS 2.1.4 working great, but I'm only not the hardcore ZFS user (only having one mirrored Pool).

 

Finally, was able to replicate the issue with RC3 as well.

Please find the diagnostics as attached.

After Extended SMART Self-test of all drives in the pool, upgraded again to RC4 from RC3.

Within half an hour or so the pool was again in SUSPENDED state.

Reverted to RC3, not sure what's the underlying cause.

zfs was working fine with RC3 earlier.

How do we debug this?

You caught me in the middle of releasing the update and there was a missing MD5.  Try again.

Thanks a lot, works as expected. Afraid the GUI pushed the notification early.

Just to let you guys know, a update for ZFS is available ZFS v2.1.4 (Changelog - not available yet but should be tomorrow)

 

The new ZFS packages are currently building for Unraid versions:

• 6.9.2
• 6.10.0-rc4

 

Should be done in about 20 minutes.

 

To pull the update please restart your server or upgrade to Unraid 6.10.0-RC4 if you want to try the Unraid RC series (if you restart your server make sure that your Server has a active internet connection on boot and is actually able to connect to the internet).

Man, I should have waited for this before moving to RC4, which caused me some grief. Back on RC3, will move once Extended Self Test is complete for all HDDs.

This is just an unfortunate coincidence, i would guess it´s cabling issues or a dying drive. Have you done a smart test?

Smart test was done last fortnight, and have weekly scrub scheduled on the pool.

I have built the system just last month with new Exos drives.

 

I reverted back to RC3 and things seem to be fine for now, will schedule a SMART test right away.

Do you need more verbose logging?

 

RC3: Linux 5.15.27-Unraid.

RC4: Linux 5.15.30-Unraid.

 

Update 1: SMART short self-test passed for all the drives.

WIth 6.10.0-rc4, pool goes offline when an attempt is made to write something into the pool.

The pool was fine till RC3.

This is the plugin version and not the ZFS version.

Thanks, and sorry for the false alarm.

Why not use the ZFS directory?

Are you really sure this worked before? But this seems like a issue with GUI itself and should reported to the bug tracker for RC3.

 

Earlier I created Unraid Shares and replaced them with symbolic link to ZFS directory. Worked like charm apart from getxattr() errors, which I was fine with. However, with 6.10.0-rc3, browsing these shares and using them during VM creation wasn't an option since they simply wouldn't work. As an alternative, I moved the ZFS shares under smb-extra.conf.

 

I have reported these under RC3, since ZFS isn't a supported FS, support isn't guaranteed.

Unraid 6.10.0-rc3 GUI still shows version as 2.1.0 even after update and restart.

Though dmesg output shows:

ZFS: Loaded module v2.1.3-1, ZFS pool version 5000, ZFS filesystem version 5

 

Also, am running into new issues with 6.10.0-rc3. While creating a new VM, the Unraid GUI is not able to follow a symbolic link to ZFS.

 

"data" is a symbolic link to ZFS. This was working fine with 6.9.2.

 

Strangely, browsing the Unraid Shares works as expected.
