Version: (using KDE 4.2.1) Installed from: SuSE RPMs I have converted my external usb drive to use ext4. Before that I was able to click and mount with dolphin. But now dolphin tries to mount as ext3, which obviously fails if the fs is using ext4 attributes like: extents. workaround: adding a new entry to /etc/fstab: /dev/disk/by-id/usb-SAMSUNG_HM250JI_SAMSUNG_HMS0TVJD0Q311736-0:0-part1 /media/DeLock250GB ext4 acl,user_xattr,user 1 1 expected: kde should be able to mount external ext4 fs without messing around in fstab.
This was an upstream bug that now seems fixed, I just convert a usb pendrive from ext3 to ext4 and it worked well. Closing the bug, if you can reproduce the bug with recent versions please, don't hesitate to reopen the bug. Thanks!
