We're trying to run Neos 3.2 on a network file system mounted on a host. I know this has some hassles and performance issues in general, but using an optimized NFS server with ZFS cache features and cache in general, performance is good for most applications.
Trying to run ./flow help on NFS gives:
Warning: Invalid argument supplied for foreach() in /httpdocs/Neos/Packages/Framework/Neos.Flow/Classes/ResourceManagement/ResourceManager.php line 539
We've tried to configure cacheDirectory (/var/tmp/NeosCache/) in Caches.yaml to use local SSD, this removes the PHP error above, but running ./flow help then causes a lot of files being generated in /var/tmp/NeosCache/ and then deleted again repeatedly, that is the process of creating and deleting files start over and over again. Seems like an infinite situation going on.
We don't know Neos internals but some of the files generated in cacheDirectory (on local SSD) looks like:
We've tried different mount options (e.g. enabling atime etc.) with NFS, but nothing really seems to make it work.
When moving all files to local SSD everything works smooth
But we would like to get NFS working since we're using it in our hosting environment based on Docker.
