BTRFS permissions [Solved]

[xh1]

Hi,
I used GParted to format a SSD to BTRFS, to be used as a backup drive. It doesn't allow me to create folders or paste/drag files into it saying I have no permissions. In GParted I see a lock sign under the partition column but at no point was I asked whether I want the partition to be encrypted.
Your help is appreciated.

Here's the QSI:

when gparted formats, the file system is owned by root.

so you need to give your user permission to use the file system. I suspect right now the user has permissions to read but not write.

you can use the commandline, but I think if the device is mounted then you should be able to open the top level folder in a "root thunar" and change the permissions in the properites for that folder.

[xh1]

I tried doing that and I'm getting a popup saying:
Failed to change the permissions of "lib". Error setting permissions: Operation not supported. Do you want to skip it?

[dolphin_oracle]

I guess I don't understand what you've done. I though you said this was a newly formatted partition, which I presumed had nothing on it.

maybe navigate to the mount point in the terminal and provide output of

Code: Select all

ls -l

Hopefully this is what you were asking for. sdb is the SSD I'm trying to use.

brtfs mounts a tad different when setting a perma Mount Point to access the drive as "Space" Windows would call it a fully other added new drive by its letter or how you administer it. Same here. but instead of the letter assignment Linux can be taught what a user might like to call it.

as any directory type per a disk no matter can be called its mounted directory or "Mount Point" have you shared Gparted formatting yes its owned here by the format building as to be has to be root:root. But that is just a start we need the UUID and even thought part-UUID and Part-Label even /dev/sdb1 etc can be used Linux now loves likes
UUID without double quotes that you can get by lsblk or blkid -o list or simply blkid listings this will show all drives found by what is plugged into your mobo. So here a few steps that might show a solution "easy peezi like " Sorry this will be running a Terminal Shell Program as in Xfce-terminal command line ol school like.
ps: one caveat - if other disks types exists and are already set as ext4 the info for entry to /etc/fstab will be tad different as too after /bigDisk we have Filesystem Type ext4 would look like ext4 defaults,data=ordered 0 2
brtfs only will take perma mount as shown solely defaults 0 2 see below.

Code: Select all

 
sudo blkid 
/dev/sdb1: UUID="d8713fbe-d1a1-4ccf-9c9f-577b27df9007" UUID_SUB="2f1b3f25-9222-4645-8e5a-de06197cbdb9" BLOCK_SIZE="4096" TYPE="btrfs" PARTUUID="145e6af6-afdf-48d8-41bd-d7f1fc2fd321"
                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
cd /etc ; sudo cp fstab fstab.org
nano or vi / vim if you prone to like either we want to open a new line above swap swap  enter a mount-point and disk settings. 
UUID=d8713fbe-d1a1-4ccf-9c9f-577b27df9007 /bigDisk btrfs defaults 0 2     # here I created a new mount-pt called bigDisk  we would in terminal cd /  sudo mkdir bigDisk Note no double quotes when I copied from blkid output
write complete quite this edit of /etc/fstab
cd /
sudo mkdir bigDisk
sudo mount -a     # this will mount your new brtfs drive type does not matter as long we use the 1st long UUID as shown  this now ties the directory name with the disk drive. 
sudo chown -R xh1:xh1 /bigDisk     # can do without the 1st forward slash but gets the job done.   this now you own it from root 1st  build ownership
sudo chmod -R 755 /bigDisk           # if you are only to use this drive can set 760  inplay of 755 which is a common umask by user creation. 
cd /bigDisk
touch test 
ls -la    -- should see test
rm test
ls -al    -- no should see - your now up and its your drive to operate as normal. 

Steps to making it yours.

@atomick ,Thank you for replying. My Linux command line chops are less than minimal and I had a hard time following your instructions once it got to the nano/vi/vim part, of with I use non.

[atomick]

See your using the new drive as temp or auto mount and not permanent mounted via a mount point.
Creating a mount point is at the root file system simply creating a Directory Name that you know to be your btrfs drive I simply exampled it via a name bigDisk
call it anything. the /etc/fstab file is where you tie the drive and directory name together via the UUID I underlined part of it, It is long as well I shared an example of my own
with what would be entered in the /etc/fstab file . This would make the drive always accessible fully recoverable via reboot and or startup boot.
the steps are pretty much start from blkid and entering this into the /etc/fstab as shown. ext4 formatted has slight difference in same entry that is all.
So Replace bigDisk with Backups and it is all the same. cmd mount -a can immediately access mount the drive without a reboot as like 'windows'
