Hello,
As I am a little hacker I told myself that it was necessary to regularly backup my OMV, so via the Backup plugin I do I backup my system partition with fsarchiver.
And I saw that Btrfs partitions had a lot of benefit including the snapshot.
So I booted on a live CD to convert my ext4 root partition to Btrfs
Code
btrfs-convert / dev / sdX1
Everything went well but during the boot grub tells me an error message and the system does not boot (I have however modified in the fstab the assembly in btrfs)
My question is would there be a modification to make in the grub to boot on the pratition btrfs ?
sorry for my bad English
