[Solved]GNOME Nautilus mounting external HD has long filenames

1. Unlike Ubuntu GNOME. Filename is predictable and short; as well as always the same.
2. Is it possible to mount from CLI without sudo?

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

I have no clue what you are asking here. How do they look like? How should they look like? What's the file system on the HDD? Can you post a comparison screenshot between Ubuntu and Arch, have you compared the mount options between the two systems, are your locale settings the same ....? Please read https://bbs.archlinux.org/viewtopic.php?id=57855 and try to state your questions in a way that doesn't mandate numerous back and forths because they lack needed information.

For the second question., you can use udisks CLI which is what all desktop environments use internally, see: https://wiki.archlinux.org/title/Udisks#Usage and other related  tools on that page

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

Maybe it is the issue of Not Naming the External HD

Tried with the HD with a name. Auto mount in Nautilus. Right click to open in Terminal.

$ echo $PWD
/run/media/polv/Passport1

Compared with another external drive.

$ echo $PWD
/run/media/polv/acfb2570-4804-4180-bbbf-5685b640a7ee

Finally, /dev/sda5. However, mounting /dev/sda5 in Nautilus required gtk-sudo or something.

$ echo $PWD
/run/media/polv/dbfe059d-773b-4d9d-9fb8-1a85f443eb1a

BTW, why it is /run/media; not /media ?

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

/run/ is a tmpfs directory that should be used for non persistent data like in this case, otherwise you'd either have media littered with directories or need to have something that explicitly removes the directories created for mount points. This is ultimately an udisks compile option that might be set on ubuntu but isn't on Arch

which versions are we talking here? Labels are not guaranteed to exist nor guaranteed to be unique, uuids are. but if I'm reading udisks logic right it will  first use the label and fall back to the uuid if the label doesn't exist: https://github.com/storaged-project/udi … tem.c#L647

Are you talking about the exact same drive or are these actually different drives that would make this discussion a moot point? Do you have labels for the drive/partition on ubuntu but not on the one for Arch?

But UUID is ridiculously long. And it uses only hex. (compare nanoid or base58)

$ lsblk -o NAME,LABEL,UUID,MOUNTPOINT
NAME   LABEL     UUID                                 MOUNTPOINT
sda                                                   
├─sda1           214F-15FA                            /boot/efi
├─sda2           8ecf8b83-41bc-4f4c-a710-96b522428106 /btrfs
└─sda5           dbfe059d-773b-4d9d-9fb8-1a85f443eb1a /run/media/polv/dbfe059d-773b-4d9d-9fb8-1a85f443eb1a
sdb                                                   
├─sdb1           2A17-2651                            
└─sdb2           e8099d6f-eca8-4031-b788-f5abf70bafdb 
sdc                                                   
├─sdc1 Passport1 8F4B-65E4                            /run/media/polv/Passport1
└─sdc2           acfb2570-4804-4180-bbbf-5685b640a7ee /run/media/polv/acfb2570-4804-4180-bbbf-5685b640a7ee

Unrelated, but I can only create Folder in udisk'd NTFS (/dev/sdc1), but not udisk'd ext4 (/dev/sdc2)...

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

So everything is as expected here? If you want a shorter name then define a label for the partitions in question. What does Ubuntu do for the partitions that don't have a label? Does it just invent a readable name? Hopefully not. If you want readable mount point names, define labels for the partitions in question.

Ext4 file systems store their permissions on the file system, you need to chown the directory you intend to have write access to to your user after mounting: https://wiki.archlinux.org/title/File_p … attributes

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

How do I create very short ID like 8F4B-65E4 or 2A17-2651 ? I know it is not that unique, though.

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

Afaik you can't and even if you could, you really don't want to do that. Why would you want to do that?

Edit: You can pass a custom UUID when creating the filesystem i.e. mkfs.ext4 -U xxxx-xxxx or with tune2fs -U for an existing (ext) file system.

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

Solved. Labeled by Gparted; Although may be possible by Disk Utility as well. It is confusing, because I had to rename LABEL, not NAME.

➜  ~ lsblk -o NAME,LABEL,UUID,MOUNTPOINT
NAME   LABEL         UUID                                 MOUNTPOINT
sda                                                       
├─sda1               214F-15FA                            /boot/efi
├─sda2               8ecf8b83-41bc-4f4c-a710-96b522428106 /btrfs
└─sda5 UBUNTUSTUDIO  dbfe059d-773b-4d9d-9fb8-1a85f443eb1a 
sdb                                                       
├─sdb1               2A17-2651                            
└─sdb2 ARCH          e8099d6f-eca8-4031-b788-f5abf70bafdb 
sdc                                                       
├─sdc1 Passport1     8F4B-65E4                            /run/media/polv/Passport1
└─sdc2 EXTERNAL-EXT4 acfb2570-4804-4180-bbbf-5685b640a7ee /run/media/polv/EXTERNAL-EXT4

Though I have a new problem. That ext4 external HD.

I can mount first, then right click to open Terminal. Then chmod 777 * without sudo.

But I can't allow creating folder that external HD root level.

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

You need to chown or chmod the actual mount point, i.e. in this case

chmod 777 /run/media/polv/EXTERNAL-EXT4

that will change the permissions for the root node of the ext4 file system.

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

Thanks, I would just type $PWD, btw.

Right click and open in Terminal from Nautilus.

  EXTERNAL-EXT4 chmod 777 $PWD
chmod: changing permissions of '/run/media/polv/EXTERNAL-EXT4': Operation not permitted
➜  EXTERNAL-EXT4 sudo chmod 777 $PWD
[sudo] password for polv: 
➜  EXTERNAL-EXT4 

Now, I need sudo.

Re: [Solved]GNOME Nautilus mounting external HD has long filenames

yes once, after you should be able to create files and directories as your normal user because the perms should allow you to.
