Subject: fuse freeze and usb devices

Message-ID: <0408cef1-683f-ec03-cdef-894f1e48b869@zoho.com> (raw)

Hello kernel experts,


I'm experiencing some fuse user space daemon freeze.

I've created a bugzilla entry so I won't repeat all the details, so see 
here:

https://bugzilla.kernel.org/show_bug.cgi?id=206643

TLDR:

mergerfs is stuck inside pread64(). system is idle, manually accessing 
one of the drives via hdparm/ls (or sync) unblocks the syscall and 
mergerfs resumes.

I have no idea which subsystem is responsible for this behaviour, as the 
scenario is a bit complex.

Thanks for your help.


P.S. Add me in CC as I'm not subscribed to the ML.
