Since qcow2 only supports metadata preallocation, not full preallocation, I'm
wondering if +C on the sparse file is sufficient, or alternatively using
qemu-create -o preallocation=metadata,compat=1.1,lazy_refcounts=on? Or is qcow2
on btrfs just not a good idea?

Hello,
Originaly I had two seperate ext4 partitions for rootand home, thenI
recently converted my root ext4 partition to btrfs primarily because of
snapshots, I also created a subvolume for /var/cache/pacman/pkg because
I didn't want the packages in snapshots and that worked out great, I
have

Hi All,
the following patches implement the recursively snapshotting and
deleting of a subvolume.
To snapshot recursively you must pass the -R switch:
# btrfs subvolume create sub1
Create subvolume './sub1'
# btrfs subvolume create sub1/sub2
Create subvolume 'sub1/sub2'
# btrfs subvolume snaps

Previously, when you did a btrfs fi show, you got a list with one output
for each btrfs storage volume whether it was a single device or
multi-device volume.
Now, I get multiple outputs for each storage vol
Hello,

combine "clear_cache" and "nospace_cache" - that should do the trick.
Then unmount and check.
Thanks and mentally noted for further reference. I didn't think about
combining the options, but it makes perfect sense no

Hi
Follow-up for the issue. I stuck with this "invalid csum for free
space extent" error. Could anyone explain what does it mean? If this
is not data and just a free space, why do we care about its checksum?
And if we do really care then btrfs should have a way to fix this
error. I can "fix" a fil
