Hi, I replied that removing snapshots had worked, but it was just
temporary. So I tried the second suggestion but after restoring
PFS errors started again.

At the end the "culprit" seems to be Chrome.

If I emtpy cache and all other temporary data, close Chrome and
prune PFS history the problem goes away. I moved lots of files
to have some changes to mirror but stil no errors. Now, if I run
Chrome again and open a couple of tabs, errors are suddenly back.

So I can't be 100% sure, but it seems quite reproducible.

Chrome is build with Synth with default options, recompiled after
upgrading to 6.4.1.

So I think the disk is ok and the problem is harmless, just wanted
to update in case someone else has the same problem.

Thanks again!
Andrea
