The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
mount -o vers=3,udp,noatime,rsize=32767,wsize=32767,async
192.168.122.1:/srv/mediawiki-vagrant /vagrant
Stdout from the command:
Stderr from the command:
mount.nfs: mount to NFS server '192.168.122.1:/srv/mediawiki-vagrant' failed: RPC
Error: Unable to receive
Running vagrant destroy -f && vagrant up doesn't help.
The instance is "wikispeech-wiki-buster" in project "wikispeech".
It's using image debian-10.0-buster.
Looking around on wikispeech-wiki-buster.wikispeech.eqiad.wmflabs, I
can see that Vagrant was able to setup the appropriate /etc/exports
entry for the server side of this. We have seen some amount of
instability with NFS & MediaWiki-Vagrant in the past. This time I have
a hunch that the problem was the client (the LXC container that
MediaWiki-Vagrant is managing) trying to mount the share before the
NFS server on the hosting instance was ready. I did `vagrant ssh` to
enter the container followed by `sudo mount -t nfs
192.168.122.1:/srv/mediawiki-vagrant /vagrant` and the share mounted
correctly. I can't guarantee that things will work correctly following
a restart of the LXC container or the hosting instance, but for now it
is working.
Sorry I don't have a more satisfying answer for you. Vagrant + LXC +
NFS can be a bit of a pain.
