Permission for external hard drive

[dooblizz]

Hi there Mageia Magicians,
I had access to an external hard drive in Mageia 4 but as I upgraded to Mageia 5, I can't get access to my files because I am not the owner and do not have permission. I have tried looking through all settings but can't seem to find it! What needs to be done to solve this issue?
Thanks

What filesystem does that hard drive use? If it is mounted, please show the output of

Code: Select all

mount
ls -al /mountpoint/of/harddrive
ls -aln /mountpoint/of/harddrive

Thanks for the quick answer Doktor, I was out of town.
I believe I formatted it to ext

Is it /dev/sdc1 ? /run/media/jay/a17961f7-38d6-431c-adde-2d2dcf71e9ae formatted as ext4?

I though it was obvious that /mountpoint/of/harddrive is a placeholder and should have been replaced by the mountpoint of the harddrive.

Please show the output of

FWIW, how did you upgrade to Mageia 5? Which of the methods from https://wiki.mageia.org/en/Mageia_5_Rel ... m_Mageia_4 did you use?

Ouch! My bad, I didn't notice that as I was in a hurry (was leaving the city).

Thanks for all your help Doktor5000, you are a wealth of knowledge.

I installed a brand new installation from Mageia 4 using a DVD!

Are you sure? In the first post you say that you upgraded from Mageia 4 to Mageia 5, and now you have the problem. When asked how you upgraded, you say that you installed Mageia 4.
But still the UID (user ID) from your current user is 1000, which implies that this user has been created under Mageia 5 fresh installation.
And if you would have done an upgrade from Mageia 4 to Mageia 5, you would have kept your old UID of 500 and would not have the problem you currently have.

There's an easy fix and a proper fix - depending on whether you want access that drive only from your Mageia 5 installation, or maybe also on installations where you have a UID of 500.
You can read more about this issue here: viewtopic.php?f=8&t=10001

[dooblizz]

Sorry for the confusion. I meant I had Mageia 4 then I did a fresh installation of Mageia 5! I want to use this hard drive with other distros so I am unsure what to do next? Do other distributions have trouble if it is 500 or 1000 UID? So it is all about the use ID being 1000 now that it can't gain permission?

[doktor5000]

Most newer distros use UID starting with 1000 for normal users. You can easily gain access if you simply change the ownership of all files and folders to your new id 1000, as root:

Code: Select all

chown -R jay:jay --from=500:500 /run/media/jay/a17961f7-38d6-431c-adde-2d2dcf71e9ae

Or you can do as explained in viewtopic.php?p=59304#p59304 and the above linked thread.
