btrfs is new to me. I’m in a need to move btrfs subvolumes to different location. How to do it correctly? I have tried snapshotting them but no matter how I specify path I alvays get “No such file or directory”
Some sample how their appear currently:
[root@d... mnt]# btrfs subvolume list /home
ID 256 gen 340794 top level 5 path @/vmguests
ID 257 gen 340794 top level 5 path @/opt
[root@d… mnt]# btrfs subvolume snapshot @/opt /mnt/temp_home
ERROR: Could not statfs: No such file or directory
BTRFS is a big B-Tree and the sub volumes are not physically distinct from the base partition. If you want to “move” or change capacities?? you could create a new portion (of any type file system) and mount to replace the BTRFS subvoume
There’s this “How-To” in GitHub – <Move your BTRFS /home subvolume to a new disk>
Path @/opt doesn’t exist. Use /opt instead.
Thanks gogalthorp, Donald and maier about your valuable hints. Currently, I’m eagerly learning about btrfs.
Please be aware that, as of Linux Kernel version 7.0 XFS now has autonomous self healing capabilities – <XFS Introducing Autonomous Self-Healing Capabilities With Linux 7.0>.
This means that, primary reason for choosing Btrfs over XFS where data integrity checking is important is now longer valid.
Donald, the link to github gist were helping alot, especially moving to home header in a gist
None of your answers gave full solution which is great since they left room for intuition and thus self learning
