TSM Commands Failing After Rebooting the Server Host with "Could not connect to server. Make sure that Tableau Server is running and try again."

Publiceringsdatum: Apr 13, 2024
Beskrivning
On Oracle 7 Linux systems, when Tableau Server's host machine is rebooted after updating the FUSE library in the OS, TSM commands will fail with the following error:
 
"Could not connect to TSM Controller."
"Could not connect to server. Make sure that Tableau Server is running and try again." 

Tableau Server may eventually recover to a working state after some time. 

Cause

According to the third-party license component (Non-ATR), Flexera noted it is expected that licensing issues will arise if the version of Fuse installed on a machine changes. Their instructions indicate a reinstall of the licensing process is necessary, but as we cannot do that standalone from Tableau Server, a clean reinstallation is the only option. 
Lösning
Solution: Perform a clean reinstall of Tableau Server, licensing included, and restore from a backup. 

Long term solution: Server Authorization To Run (ATR) licensing is not impacted by FUSE library updates. To proactively avoid this issue being caused by future FUSE library updates, implement Server ATR licensing when reinstalling or when next planning to upgrade Tableau Server to a new version. (See Using a Blue/Green approach for upgrading Tableau Server.)

Workaround: As a workaround to enable future FUSE library updates without implementing Server ATR, work with your IT department and arrange to create new server hosts with the FUSE updates already installed when FUSE library updates are required, then migrate your production Tableau Server to those already-updated hosts.

To identify this issue:

1. Check the yum.log file (RHEL systems) or dpkg.log (Debian) to see if Fuse libraries have been updated since the install of Tableau Server.

Note: at this time, only Oracle Linux 7 systems have been found to be affected by this issue. See the Related Links on this page for other possible issues if this one is not a match.

2. Additionally, systemd logs (/var/log/messages or /var/log/syslog) will show FNP Licensing Service and TSM services repeatedly restarting:
  
Nov 09 14:50:20 o143006d systemd[5227]: Unit fnplicenseservice_0.service entered failed state.
Nov 09 14:50:20 o143006d systemd[5227]: fnplicenseservice_0.service failed.
Nov 09 14:50:20 o143006d systemd[5227]: fnplicenseservice_0.service holdoff time over, scheduling restart.
Nov 09 14:50:20 o143006d systemd[5227]: Stopped Tableau Server FNP Licensing Service.

In the same log, there will eventually be messages showing that FUSE has failed and exited:

Nov 09 14:50:20 o143006d FlexNetFs[19593]: Entering fuse_main
Nov 09 14:50:20 o143006d FlexNetFs[19593]: Exited fuse_main - Failed
