Maybe I overlooked the obvious: if Chrome holds a lock on that file when you suspend, and if you stay in suspend for longer than the NFSv4 lease time (default 90 seconds), then the client will lose its lease, hence any file locks. I think these days the client then returns EIO on any further IO to that file descriptor. Maybe there's some way to turn off that locking as a workaround. The simplest thing we can do to help might be implementing "courteous server" behavior: instead of automatically removing locks after a client's lease expires, it can wait until there's an actual lock conflict. That might be enough for your case. There's been a little planning done and it's not a big project, but I don't think it's actually at the top of anyone's todo list right now, so I'm not sure when that will get done. --b. > > > >--b. > > > >> > >> > >> > >>>On 10/4/20 6:53 AM, Kenneth Johansson wrote: > >>>>So I have had for a long time problems with google chrome and > >>>>suspend resume causing it to mangle its sqlite database. > >>>> > >>>>it looks to only happen if I use nfs mounted home directory.
