Keeps system from suspending

[paulmenzel]

Linux’s FUSE maintainer suggests to disconnect any mounts when suspending:

Can this be worked around?

Yes, killing the sshfs process will enable the suspend to continue.

I suspect it would make sense for the suspend scritps to perform this
by default, since the ssh connection will likely be broken anyway
after resuming.

Could such suspend scripts be provided?

killall sshfs doesn't seem to need a special script...

FYI: On macOS SSHFS / FUSE do not create an assertion to stay awake.
This itself does not say that sleep/standby/wake works flawlessly.
I just say that the typical mechanism in which background processes block sleep (by pmset assertions) is not used from SSHFS / FUSE.

SSHFS does not prevent system sleep on macOS. It's not easy to do the right thing in this situation: Prevent system sleep, unmount the volume, possibly remount the volume when waking up, ...

Unmounting the volume might not be possible without user intervention. There might be open/unsaved files. Remounting the volume might not be possible without the user entering their password again.

If you come to the decision that preventing system sleep is the right choice then you should follow macOS standards and set a pmset assertion. Then macOS will leave the machine on indefinitely (for stationary Macs or MacBooks with the power adapter connected) and only will go to sleep when the battery runs short.
