Nice, you should probably update the btrfs wiki as well, because there is
no mention of btrfs-dedupe.
First question, why this name? Don't you plan to support xfs as well?
Second question, I'm trying deduplication tools for the very first time and
I still have to figure out how to handle snapper snapshots, which are read
only. I currently tried duperemove 0.11 git and I get tons of "Error 30:
Read-only file system while opening "/.../@snapshots/4385/...". How am I
supposed to handle snapper snapshots?
I do not run duperemove from a live distro, instead I run it directly on
the system I want to deduplicate:
sudo mount -o noatime,compress=lzo,autodefrag /dev/mapper/cryptroot
/home/niko/nosnap/rootfs/
sudo duperemove -drh --dedupe-options=nofiemap
--hashfile=/home/niko/nosnap/rootfs.hash /home/niko/nosnap/rootfs/
Is btrfs-dedupe able to handle snapper snapshots?
Thanks,
Niccolo' Belli
