WebGUI shows no data and SMB stopped working

Description

I have a strange behavior at my system:

If i logging on at the WebGUI the the loading bar at the top spinns while i fill my login information (see 3. file attached). After successful entering root credentials, the splash-screen changes to show the dashboard.

So far so good.

But: The dashboard is empty. If i navigate to the "Pools" entry the loading circle spinns, but nothing happens. If i go to the "Advanced" Entry to save a debug dump for support, all fields are empty and if i push the "Debug" button nothing happens.

An "zpool status" shows that all pools are online and i can access all pools via ssh. Also the Boot-Pool seems healthy (mirrored).

The strange thing is that if i try to create a debug from command line, the debug script always hangs at "iocage list @1602260832".

The next strange thing is that SMB stopped working over night or so without any information or hint. At WebGUI the service seems running an if i stop the service and restarting it seems stopping the smbd-daemon and restarting it. But i am not able no access the shares from other clients. The shares are listed if i select the server, but if i click on an share at an windows or linux system it seems to be to come to an timeout.

I also tryied to restart the smbd-dameon via cli (middleware-command an via service-command) but that seems nothing to change.

I tried this with Microsoft Edge (Chromium), Chrome and Firefox. I cleaned all caches, but the WebGUI or something in between to the webserver and middleware seems broken. I try to let the system as long as possible in this stage, if you need more information or logs...

I attached screenshots of the WebGUI and the "hanging" debug-attempt.

Thanks for the update, good to know!

may have an idea what the very unusual system behavior raises.

To backup an data directory via the cloud tasks of an other VM i mounted an CIFS share at /mnt/Mailstorage_SMB. I have mounted this directory since years without any problems, but this is the most "unusual" thing that i can think of.

I think something strange happens at the mount or the remote file system is not accessible i think that "collectd" can not collect the SMB-share information anymore and hangs. It cant collect the drive information and the middleware runs in an timeout and no dashboard is available...

Probably this an very stupid domino-effect that i raised.

 

I rebooted the system directly after i updated to RELEASE and disabled that mount-command that no remote mount points are available anymore. So far so good, i now have about 7 days uptime...

This is actually because of sysctl that SNMP agent retrieves by default. This will be fixed in 12.0-U1.

Today i have updated the system to RELEASE.

With this release now the system has much lower memory consumption and the ARC-Cache goes never over 5.6 GB...

Every few seconds an python3.8 process spawned and used approx. 100 % CPU and the host system freezes in this time:

After i checked "htop" the SNMP Agent seems to generate very high I/O and CPU usage and let the system freeze. After i disabled the SNMP service via the WebGUI (red arrow) the freezes disappeared.

I am not sure if this is an new "bug" with RELEASE or this old bug now is more obvious with the RELEASE...

Nothing. Between yesterday and today evening nothing was changed. A few devices access the shares periodical.

I have multiple cloud sync tasks and currently there is no free space left at Dropbox, so the rsync process return an error. But i am unable to disable the tasks without working GUI.

The command "zfs get -H -o name,property,value -t filesystem all DATA1 DATA2 DATA3 VM_DATA3 VM_DATA4 freenas-boot" seems not to exit and hangs.

If i execute the command in console, it stops at:

"zpool status" seems fine....

Should i try to upgrade to the new ZFS feature flags? I am not sure, because i cannot use the pools at any "stable" version anymore...
