I'm running Linux Mint 18/2 with 4.10.0-38-lowlatency kernel and KDE5 desktop.
I'm testing lots of USB flash memory with a custom bash script and
f3 and I had a strange situation today. One drive didn't disappear from /dev/ when it was physically disconnected from the machine.
I also noticed that any
sync command will completely hung up and even
sudo pkill -9 sync doesn't help there.
I finally did
sudo rm /dev/sdd, but
sync still will hung forever.
All sync processes that were run since the error started remain in the system. Htop says they all do I/O all the time:
Anybody had something like this? Can I fix this without rebooting the machine?
