Dear BTRFS folks, I’m using snapper in openSUSE.
For learning purpose I did
% snapper rollback.
It was more like a curiosity reason about snapper, but become a blunder.
BTRFS Mount Trapped in Snapper Rollback
% snapper rollback, my
% snapper list become empty.
And this strange error message from snapper.
It seems like root filesystem mounted to a snapshot volume as shown in command below.
How do I solve the issue, undo the rollback to my normal filesystem ?
The answer is, add
.snapshots entry in
Before The Issue
I actually had wonderful life with snapper.
Setup Subvolume for Root
Some Cool Commands
Or if you wish, summary using line count.
Make a snapshot
Solving The Issue
First I need to add this line to /etc/fstab
and mount it, no need to reboot.
Get current snap
In my case, previously I have snapshot number 75.
This is below just an example.
I decide to go back to 45.
Get BTRFS ID
I find the ID of 45, it is 355.
To make it writable
And make it default
Remove the annoying snapshot.
I have to learn about the basic of BTRFS before going back to snapper !
Thank you for reading
