Filehandles to /run/docker/plugins/azurefile.sock are not closed

sascha-egerer commented 8 years ago

Looks like file handles to /run/docker/plugins/azurefile.sock are not closed. After (re-)starting some containers with a azurefile volume i get a "Too many open fiels" error.

$ sudo lsof  | grep /run/docker/plugins/azurefile.sock | wc -l
7140

$ sudo initctl restart azurefile-dockervolumedriver
azurefile-dockervolumedriver start/running, process 15863
$ sudo lsof  | grep /run/docker/plugins/azurefile.sock | wc -l
4

@sascha-egerer hmm could these be connections from docker engine to the volume driver? could you please run the lsof command without wc -l and run ps aux to see list of processes that have open handles to the socket?

There is something really odd going on here. Maybe the main problem was created by docker-compose as i've the defined the volume there and i think docker-compose tries to create the volume every time doing a docker-compose up. But i could reproduce it like this:

$ sudo service azurefile-dockervolumedriver restart
$ sudo lsof | grep azurefile | wc -l
45
$ docker volume create -d azurefile -o share=foo --name=foo
foo
$ sudo lsof | grep azurefile | wc -l
79
$ docker volume rm foo
foo
$ sudo lsof | grep azurefile | wc -l
79
$ docker volume rm foo
foo
$ sudo lsof | grep azurefile | wc -l
85
$ docker volume rm foo
foo
$ sudo lsof | grep azurefile | wc -l
91
$ sudo lsof | grep azurefile

So after every $ docker volume rm foo there are new handles that are not closed.

Maybe this is related to #20

@sascha-egerer thanks this is very insightful. I will debug.

ahmetb commented 8 years ago

Thanks for reporting, just fixed this in master, feel free to compile from source until I release a new version tag.

Looks like there is still a problem. Everytime i start a container the volume is mounted again under the same path.

yeah this is a separate issue, thanks for opening #23.
