 |
|
Hi.
I'm running a standard configuration of udev, udisks and polkit. That is, I have never touched their out-of-the-box configuration.
If an external USB storage device is plugged in, as a regular user, I have the possibility to mount its partitions from the Plasma tray (KDE user here), using the "Disk and devices" widget. Because polkit allows it, the mount succeeds, but the mounted NTFS filesystem is owned by root and uses the standard umask, so the partition is basically read-only for me (I can become root, but that's out of the question as a solution).
Another external device (an SD card) that is formatted as FAT is mounted just fine with all files belonging to my user and my default group. The mount documentation shows that this is default handling for uid and gid mount options for both FAT and NTFS filesystems.
I went on and placed the supposedly built-in configuration of udisks in the /etc/udisks2/mount_options.conf configuration file
| Code: | ntfs:ntfs3_defaults=uid=$UID,gid=$GID
ntfs:ntfs3_allow=uid=$UID,gid=$GID,umask,dmask,fmask,iocharset,discard,nodiscard,sparse,nosparse,hidden,nohidden,sys_immutable,nosys_immutable,showmeta,noshowmeta,prealloc,noprealloc,hide_dot_files,nohide_dot_files,windows_names,nocase,case

(yes, I'm using the kernel driver), then unmounted and reinserted the USB storage device. No change, the NTFS partition is still mounted owned by root. I checked the standard configuration of udev for udisks and found nothing to explain why the settings above do not take effect  |

Hi,
I using it for my external USB-Disk with a fstab entry, whit the user mount option. | working fstab example entry: | | PARTUUID=70df7e72-8b3a-4b20-afd8-1cf4xxxxxxxx /mnt/mypassport ntfs3 noauto,user,prealloc 0 0 |
udisks respects this entry - and it works with the kde plasma device notifier too. |

| OP: after this is mounted, what does the /proc/self/mountinfo line for this filesystem show? The first step is to understand whether your mount options are present but ineffective, or missing entirely. |
