Recently, I have found one issue in my Ubuntu server where I have installed the Tableau server. The tableau server was not running and I tried to restart this server still nothing happened.
Later I tried to check file storage so I executed the command df -h. It showed the following output.:
df: /dev/shm/FlexNetFs.43387: Transport endpoint is not connected df: /dev/shm/FlexNetFs.29010: Transport endpoint is not connected df: /dev/shm/FlexNetFs.01960: Transport endpoint is not connected df: /dev/shm/FlexNetFs.79422: Transport endpoint is not connected df: /dev/shm/FlexNetFs.58199: Transport endpoint is not connected df: /dev/shm/FlexNetFs.39559: Transport endpoint is not connected df: /dev/shm/FlexNetFs.89392: Transport endpoint is not connected df: /dev/shm/FlexNetFs.63002: Transport endpoint is not connected df: /dev/shm/FlexNetFs.60694: Transport endpoint is not connected df: /dev/shm/FlexNetFs.01945: Transport endpoint is not connected df: /dev/shm/FlexNetFs.18509: Transport endpoint is not connected df: /dev/shm/FlexNetFs.58647: Transport endpoint is not connected df: /dev/shm/FlexNetFs.78818: Transport endpoint is not connected df: /dev/shm/FlexNetFs.46938: Transport endpoint is not connected df: /dev/shm/FlexNetFs.30484: Transport endpoint is not connected df: /dev/shm/FlexNetFs.14921: Transport endpoint is not connected df: /dev/shm/FlexNetFs.35551: Transport endpoint is not connected Filesystem Size Used Avail Use% Mounted on udev 7.7G 0 7.7G 0% /dev tmpfs 1.6G 8.8M 1.6G 1% /run /dev/nvme0n1p1 49G 29G 21G 59% / tmpfs 7.7G 4.0K 7.7G 1% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 7.7G 0 7.7G 0% /sys/fs/cgroup /dev/loop0 18M 18M 0 100% /snap/amazon-ssm-agent/1566 /dev/loop1 29M 29M 0 100% /snap/amazon-ssm-agent/2012 /dev/loop2 97M 97M 0 100% /snap/core/9665 /dev/loop3 97M 97M 0 100% /snap/core/9804 tmpfs 1.6G 0 1.6G 0% /run/user/999 tmpfs 1.6G 0 1.6G 0% /run/user/1000
It seems that there is some problem on /dev/shm volume. Hence, I unmounted it with the following command:
sudo fusermount -uz /dev/shm
Now, I restarted my Tableau server and it worked.
