Answer 1

I had the same problem.

All you need to do is change the type of the synced_folder to nfs, but that option only works with Mac hosts.

To be able to use it in Windows, you need to install vagrant-winnfsd

$ vagrant plugin install vagrant-winnfsd

Then change the type of the synchronisation in your Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.synced_folder "../project", "/var/www", type: "nfs"
end

The documentation says that it is also needed to change the type of the network to dhcp, but I didn't need to do that to solve my problem.

config.vm.network "private_network", type: "dhcp"

I hope this helped

Answer 2

If you happened to use FAT/FAT32 or another file system with severely limited timestamp range, then that warning is to be expected.

Symfony's FilesystemCommonTrait::write() method calls touch() function with unix timestamp 0 to force expire cached content. Unix timestamp 0 represents 1970-01-01 date. In FAT file system the allowed timestamp range is 1980-01-01 to 2099-12-31, according Wikipedia. So the touch() function fails and a warning is issued.

The workaround is to modify the FilesystemCommonTrait::write() method, around line 80.

Find lines:

if (null !== $expiresAt) {
    touch($this->tmp, $expiresAt);
}

Insert before those lines:

if (0 === $expiresAt) {
    $expiresAt = time() - 1;
}

This should achieve virtually the same result by instantly expiring the cached content, but without using an invalid file system timestamp.

Alternatively, change the file system type.
