Web interface not working

[Fabien Rouach]

On my quadstor 3.2.15 the web interface doesn't answer anymore, but anything else still working.

Any way to restart the web interface without restarting the whole server?

Thanks

Hi,

A restart is most likely needed. Proabably one of the kernel tasks
hung or the mdaemon itself.

Please check for any core files under /
ls -l /core*

If you find any, please run a file command on the core file to see if
its related to 'mdaemon'. If yes Please try the following

yum install -y gdb
gdb /quadstor/sbin/mdaemon <path to core file> -batch -bt > /tmp/trace.out

Then send us /tmp/trace.out

If there are no core files and if mdaemon is still running (ps -aef |
grep mdaemon) please try
yum install -y gdb
gstack <mdaemon pid> > /tmp/trace.out

Then send us /tmp/trace.out

Also please try the following and send us /var/log/messages
echo t > /proc/sysrq-trigger
sleep 30
