[solved] xfce thinks USB is read-only when copying files

fukawi2 · 2013-05-13 02:44:36

Still building my new desktop

I have a 32gb USB3 flash drive; when I plug it into the system, it is auto-mounted and `mount` confirms it is read-write:

/dev/sdd1 on /run/media/fukawi2/32GB-USB3 type vfat (rw,nosuid,nodev,relatime,uid=1537,gid=1537,fmask=0022,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)

Writing new files/folders works fine in Thunar; right-click Create Folder or Create Empty File creates the files and I can delete the files too.

Trying to copy existing files (from my ~) throws and error though: "The destination is read-only". Doesn't matter what files/folders, it doesn't like it. Which I find very very strange.

So does anyone know what xfce has been smoking on my machine?

What are you using to automount?

According to mount: uhelper=udisks2

Whoops... I thought I had scrolled over all the way. I guess not.

Is the outcome the same if you try to mount manually?

apoc ~ # mount -o uid=1537 /dev/sdd1 /media/USB
apoc ~ # ll /media/
total 16K
drwxr-xr-x 2 root    root   0 May 13 12:00 backup
drwxr-xr-x 5 fukawi2 root 16K Jan  1  1970 USB

Now I can't write to it at all, even though I'm logged in as 'fukawi2' (I have to be, there's no other users. Opening terminal and checking `whoami` confirms too) and you can see perms are 755 owned by 'fukawi2'

EDIT: I can write to it thru the terminal as 'fukawi2' (`touch /media/USB/test` works)

That is really funky... and this only happens with this one stick?

/me test another flash drive (USB 2.0 this time)... Nope, same behaviour with both.

Anything interesting in the logs? What does mount say about how the volume is mounted?

Searching for the thunar-volamn error finds this thread:

I have gvfs and it's optionals installed:

pacman -Q | grep gvfs
gvfs 1.16.1-2
gvfs-afc 1.16.1-2
gvfs-smb 1.16.1-2

And I start xfce using dbus-launch in ~/.xinitrc (not sure if this is still the 'right' way?)

exec dbus-launch --exit-with-session startxfce4

OK, I just remembered I hadn't rebooted since -Syu this morning.

Rebooting seems to have solved it. Thanks for the input guys!

Sounds like this post belongs in the Newbie forum.

Yeah probably... I'm not used to having to restart to get things working... I don't need to on servers and I don't use Windows

With windows you don't need to restart anyway, as the machine will just do it for you. Probably at the most inconvenient moment possible.
