ext3 or 4 to btrfs possiable

I’m planning on doing a fresh install of 12.1 reformating all but the /home, is it possible to convert ext format to brtfs? I’m real interested in the snapshot capability which is a godsend in the netapp world.

Certainly not!
You can not convert any format to any other format, except ext2->ext3->ext4.

It is possible:

Just remember that you need a separate /boot partition because GRUB Legacy can’t boot from BTRFS.

Slipion81 beat me to it. I was reading about this in-place conversion yesterday and found it interesting.

Interesting. First time I see a filesystem conversion tool like that.

I like the idea of keeping a dedicated /boot partition, I know it wasn’t necessary using a modern Linux but it has it’s uses still like large md raid devices etc.

It is necessary if your root filesystem is btrfs, because legacy grub does
not support it.
