Hdd access denied after coversion from ext4 to btrfs

[drjam2]

Hello.
I have 2 hdd /dev/sdb1 for Garuda and /dev/sda1 for general use.
$ cd /hdd/sda1; then
$ sudo btrfs-convert /dev/sda1
copying from /dev/sdb1 to /dev/sda1 not possible. Then
$ sudo chmod -R -v 777 *
--and still cannot access drive.
Please assist.

Why do you post hdd access in firedragon?

Did you read, search about?
Also missing your garuda-inx output as text.

Did you remount it as btrfs after converting?

@drjam2

sudo chmod -R -v 777 *

You should pretty much never do this. That makes every file on the device executable.

@drjam2

cd /hdd/sda1

Is this a real directory on your system? It is unusual to put a mount point right in the root folder (typically you would put it in /mnt or /mount or /media or something). If you do, root will own the directory by default.

@drjam2

sudo chmod -R -v 777 *

Usually to get control of your disks you don’t want to use chmod, you want to use chown. Since you created a directory in a system folder using sudo, root owns the folder. Adjusting the permissions to 777 sometimes still doesn’t get you the access you need.

sudo chown drjam2:drjam2 -R /hdd

This is assuming the path you noted above (/hdd) is valid, and the correct mountpoint. Obviously substitute your username on the computer for drjam2.

Hi
I removed /hdd under root. Thanks for the advice. I am not so good at the btr file system. Below is my /etc/fstab content.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).

should I simply issue the following commands:

sudo mount -t btrfs /dev/sda1 mnt (?  or /mnt)

then unmount

sudo umount /dev/sda1

then

sudo nano /etc/fstab

and add the line below to the content of the fstab

/dev/sda1       /home/user/disk btrfs    defaults        0       0

then mount everything

$ sudo mount -a

Thanks for the advice and the patience.

I agree, the code formatting especially makes a difference when you are trying to read it. If you put three tildes (~) before and after a code it changes from this:

~~~
╰─λ lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
sda
└─sda1
btrfs 00fc4cad-8f26-40a2-badd-ce019c91fb26 915.8G 2% /run/media/johan/00fc4cad-8f26-40a2-badd-ce019c91fb26
~~~

To this:

╰─λ lsblk -f
NAME FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
sda
└─sda1
btrfs 00fc4cad-8f26-40a2-badd-ce019c91fb26 915.8G 2% /run/media/johan/00fc4cad-8f26-40a2-badd-ce019c91fb26

You also forgot to post garuda-inxi!
