Can't turn off verbose logging

[DaveAtFraud]

One of my mhvtl installations seems to be stuck in verbose logging mode. The flood of detailed logging messages makes it difficult to work other issues. Example:

Feb 5 09:27:15 bend /usr/bin/vtllibrary[403379]: processMessageQ(): 10: Received from sender id: 32768, msg : verbose Feb 5 09:27:15 bend /usr/bin/vtllibrary[403379]: processMessageQ(): verbose: disabled at level 0 Feb 5 09:27:57 bend systemd[1]: Started Amanda Backup System. Feb 5 09:27:57 bend systemd[1]: amanda-udp.service: Deactivated successfully. Feb 5 09:27:57 bend systemd[1]: Started Amanda Backup System. Feb 5 09:27:57 bend kernel: mhvtl:_mhvtl_queuecommand_lck: (4265973) 12 bytes b8 11 00 01 00 01 00 00 0f e8 00 00 Feb 5 09:27:57 bend systemd[1]: amanda-udp.service: Deactivated successfully.

Note that I have set the verbosity to disabled but I'm still getting the mhvtl_queuecommand_lck messages. The above is a partial sample from doing an amanda amcheck. I'm also getting rsyslogd complaints like the following when the actual backup runs.

--------------------- rsyslogd Begin ------------------------

**** Unmatched entries **** imjournal: 54133 messages lost due to rate-limiting (20000 allowed within 600 seconds) : 1 Times

Just for completeness:

[root@bend ~]# cat /var/log/messages | grep 'Feb 5' | grep mhvtl | wc -l 41345

Hi David, Thanks for the report. The messages are derived from the mhvtl.ko. To stop the sys_emit() from the kernel module : cat /sys/bus/mhvtl/drivers/mhvtl/opts (Should be '0' for no logging : 1, 2 or 3 - where 3 is max logging) echo 0 > /sys/bus/mhvtl/drivers/mhvtl/opts (will stop it - non persistent across module reload) grep VTL_DEBUG /etc/mhvtl/mhvtl.conf is persistent (if using systemd startup to load.)

otherwise : stop daemons, unload kernel module, load with opts set to '0' and restart daemons. systemctl stop mhvtl.target rmmod mhvtl modprobe mhvtl opts=0 systemctl start mhvtl.target

Please let me know if the above makes sense (and more importantly that it worked :) )
