I have this mount point configured in /etc/stab

sshfs#tomcat8@10.1.0.73:/opt/cache /opt/cache  fuse defaults,allow_other,nonempty,delay_connect  0 0

But seems it's not working as desired, as mount gets disconnect every now and then. Any ideas on which config file or log to look for possible diagnosis?

  • can you check if manually mount without fstab works, and still disconnect? – darvark Mar 23 '17 at 17:24
  • it doesn't disconnect immediately, so actually cannot guarantee if it'll stay mounted if I remount it manually. By your suggestion, should I comment it out of fstab, mount it manually and just wait to see what happens? The problem with that is eventual server reboots. – Gonzalo Vasquez Mar 23 '17 at 17:28
  • Yes, the best option to debug is comment fstab, and do it manually, eventually add verbose mode to sshfs by -o sshfs_debug – darvark Mar 23 '17 at 17:32

Your connection is probably cut by a firewall due to inactivity (lack of TCP frames pertaining to the SSH connection). Try to enable keep-alive.

In your /etc/ssh/ssh_config, add:

TCPKeepAlive yes
ServerAliveInterval 30
ServerAliveCountMax 10

  • Sounds quite a good answer, as actually this setup is in AWS, between two different Availability Zones, where there obviously must exist a firewall in between. Will try it and let you know the results – Gonzalo Vasquez Mar 23 '17 at 17:51
  • added "metric" no monitor the results, will let you know what happens, thanks! – Gonzalo Vasquez Mar 24 '17 at 15:58
