What we don't see is any open zvo= ls.=20 And since zfsd doesn't change any in-kernel state, I really don't see any w= ay that it could interfere with the VM. Unless you can come up with steps to reproduce starting from a clean system, I don't think it would be productiv= e to investigate zfsd any more. > I tried to access nested zpool from the host after setting > vfs.zfs.vol.recursive=3D1 to workaround the issue old way, by performing > snapshot cleanup, but it seems to be impossible after switching to stable= /14. In what sense does it "seems to be impossible"? What kind of error do you = get when you try this? --=20 You are receiving this mail because: You are the assignee for the bug.=
