[SOLVED] ZFS tools hang after upgrade to 11.0.0.4.3252

[oops741]

After upgrading N4F to x64-11.0.0.4.3252 and following the suggestions in the 'read me' (clear config and import disks, synchronize configuration), when checking ZFS, Information has:
" pool: Pool1
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support"

The pool is accessible, but trying to run ZFS, Tools causes the web-gui to hang.

Tried to execute 'zpool upgrade' from the web gui Tools, Command, but the Disks, ZFS, Tools still hangs.

Any ideas?

Any ideas?

Yes.

Upgrade your pool if your plan is continue using N4F 11.x

Need to upgrade ZFS core is normal and not a big problem, plesea read about: http://docs.oracle.com/cd/E19253-01/819 ... index.html

If you experience problems, please use Shell, and post the output of the command:

eg:

Code: Select all

zpool upgrade

and zpool upgrade -v

example:

Code: Select all

rnas: ~# zpool upgrade -v

[oops741]

Raul,
Thanks for the quick and detailed response. Is it possible to enter these zpool upgrade commands from the web-gui, Tools, Command?

[oops741]

Could not access Disks, ZFS, Tools (this is the part the 'hangs' the web-gui).
Tried to use the web-gui Tools, Command.

Code: Select all

zpool upgrade

Output was

Code: Select all

$ zpool upgrade
This system supports ZFS pool feature flags.

All pools are formatted using feature flags.

output:

Some supported features are not enabled on the following pools. Once a
feature is enabled the pool may become incompatible with software
that does not support the feature. See zpool-features(7) for details.

After restarting the N4F box (using a keyboard connected directly to it), ran

	still be used, but some features are unavailable.

Unfortunately, the web-gui Disks, ZFS, Tools still causes the web-gui to hang...

[JoseMR]

The Disks, ZFS, Tools still hangs. Is there anything else that can be done?

Hello oops741, you can enable SSH with permit root login then try to access the WebGUI ZFS tools, after the GUI hang, you can SSH login trough WinSCP to "/var/log" and zip/tar the logs files, then post here a brief system specs of the affected server followed by the zip/tar archive, this can help to sort out the root cause.

Regards

The Disks, ZFS, Tools still hangs the WebGui. So far had issues with SSH access, so hope for another solution.

Cheers

[raulfg3]

sometimes, save the actual config and do a fresh embeded re-install and restore config solve errors like this.

Thanks. Will try to re-install and restore config.

[oops741]

Tried the fresh embedded re-install, then restored config, but the problem of Disks, ZFS, Tools causing the web-gui to hang is still there.
While it is possible to perform ZFS management through Tools, Command it is still an issue.
On my other N4F box I am considering going back to 10.3.0.3.3105 (as the ZFS version there was not upgraded).
On a third N4F box with a single ZFS pool, it does not have an issue with ZFS, Tools after a similar upgrade...

[bgold]

How long have you let it sit on loading before closing the web gui? It seems that the new tools interface does load slow and even slower if there is any activity on the pools.

Previously waited for more than 10 minutes at a time. Trying to wait longer this time, so far after 20 minutes it is still hanging ('spinning wheel'). I'll wait some more time, but suspect that it won't make a difference.

could you please post the output of the following (please zip):

Tried to get the
zdb -C Pool1
zdb -C pool2
but attempting to do that through the WebGui (Tools, Command) causes it to hang...
Tried through SSH (Putty) and after a long wait got the response

Code: Select all

zdb: can't open 'Pool1': Permission denied

Code: Select all

$ zdb -C Pool2
zdb: can't open 'Pool2': Permission denied

Enclosed is the kern.geom.confxml output (device serial numbers removed).

Any ideas?

Not sure how to permit root login in SSH.
Here are some recent log files from "/var/log" (slightly sanitized) (downloaded through the WebGui, but not sure if these capture the 'hand event').
These are from the N4F2 described in the signature.

[oops741]

could you please post the output of the following (please zip):

zdb -C Pool1
zdb -C pool2

Found how to SSH as root, so here are the 2 requested outputs (took a very long time, more than 72 minutes for the larger Pool1)

Thanks for looking into this

[oops741]

Found a 'workaround', which is to install 10.3.0.3.3286 over the same USB stick and import the last saved configuration on the NF42 box. Now both Zpools on this box can be accessed and the Disks|ZFS|Tools can be accessed without 'hanging' the WebGui. Note that the ZFS version was upgraded during earlier attempts to resolve the hanging WebGui issue on 11.0.0.4.3252. Looks like 11.0.0.4.3252 needs some fixes.

Thanks for the input.

Developers still try to find the offending code, but your input are really apreciated.

[ms49434]

Reading the pool configuration straight from the disks seem to cause issues on some installations. We've developed a module that reads the configuration from the cache instead. Performance looks promising.

improvement: ability to read zfs tools configuration from cache
https://sourceforge.net/p/nas4free/code ... l_info.inc

[oops741]

The issue of hanging WebGui when using Disks|ZFS|Tools is now resolved after same N4F1 box had x64-embedded-11.0.0.4.3305 installed and previous configuration restored.
Thanks!
