[Resolved] Strange USB Disk Mount via Dolphin & systemd

schimpfj · 2014-01-01 18:56:03

Happy New Year everybody.

Having strange issue with usb drive connected to my laptop. Have not done for a long time, I believe never since migrated onto systemd, i.e. no udev is installed anymore.

Mounting usb drive via kde/dolphin seem to work fine but neither can my (less privileged) user nor root write to drive:

ERROR:

MOUNT - mounted read-write:

CREDENTIALS:
Dirs & files mounted do have correct credentials. Only upstream credentials look a bit weird but I doubt I should change those else 'other' would become write access. Despite I doubt those changes would be permanent but rather temporarily until reboot only.

Having udisks2 installed.

Someone having any idea what's going on or experiencing same issue? Shouldn't USB devices be plug&play these days - at least it used to be (udev).

Of course, I tried Google but findings where either udev related or not mounting at all, which is working for me.

Edit: Beautification
Edit2: Solved

Why are you using such an old kernel?

Also, please use code tags https://wiki.archlinux.org/index.php/Fo … s_and_Code

dev/sdb2 on /run/media/jochen/5271004B02F56D17 type ntfs

Are you using ntfs-3 ?? Out of the box, Arch does not support writing to NTFS file systems. Most USBs (out of the wrapper) are vfat. Maybe that is why it has worked in the past.

Edit: Snaked by jasonwran -- again. Good catch on the old kernel.

Wouldn't call this an old kernel but maybe for a rolling release... Will consider upgrade. But I rather think ewaller's hint re ntfs-3 points to the right direction. Will work on this (not today though, wasn't expecting that fast response). Thx both

ewaller · 2014-01-01 19:16:23

As to the kernel, you are right -- it is not that old. It is an indication that, perhaps, people are performing partial upgrades. That is the root of a great many problems. Those of us who hang out here treat that as a warning flag.

schimpfj · 2014-01-01 19:18:02

Actually fix suggested by ewaller was easier than thought. Installed ntfs-3, no additional config required - fixed! Thx again for the good solution & very swift response!
