Turns out you can't remount the device after ejecting it Reproducible: Always Steps to Reproduce: 1. Plug in USB key 2. Eject usb key via systray -> devicenotifier 3. Try to remount the usb key via devicenotifier Actual Results: Can't remount usb key Expected Results: usb key is remounted after ejecting it Plasma workspace is at 6d88ac8
I think it's a middleware or even kernel level issue. since this happens here also on plasma1, and the device file associated to the partition (like, /dev/sdb1) disappears as well
I can reproduce this in Dolphin 4. However, it also doesn't seem to be a problem with udisks or solid. I just mounted and unounted and remounted with solid-hardware5 and that worked fine. Everything was updated in the Plasma UI perfectly too. $ solid-hardware5 mount /org/freedesktop/UDisks2/block_devices/sdc $ solid-hardware5 unmount /org/freedesktop/UDisks2/block_devices/sdc $ solid-hardware5 mount /org/freedesktop/UDisks2/block_devices/sdc Bustle logs seem to show the same dbus commands going to solid from both solid-hardware and from plasma. I'm a bit lost. I'll talk to afiestas.
Created attachment 86743 [details] Bustle screenshot. Bustle screenshot. First setup + teardown comes from konsole Second pair comes from the plasmoid. All args are the same.
I think the devicenotifier (or something inside Solid which you don't trigger when you manually unmount via cmdline) powers off the device (so your external HDD doesn't keep spinning) but that way you cannot mount the device again without unplugging it first. Lukas?

Yeah, effectively the same as Bug 402660. *** This bug has been marked as a duplicate of bug 402660 ***
