I think that for the systemd uses cases (singled device FS), a simpler
approach would be:
fstatfs(fd, &sfs)
needed = sfs.f_blocks - sfs.f_bavail;
needed *= sfs.f_bsize
needed = roundup_64(needed, 3*(1024*1024*1024))
Comparing the original systemd-homed code, I made the following changes
- 1) f_bfree is replaced by f_bavail (which seem to be more
consistent to the disk usage; to me it seems to consider also the
metadata chunk allocation)
- 2) the needing value is rounded up of 3GB in order to consider a
further 1 data chunk and 2 metadata chunk (DUP))
Comments ?
I'm still wondering if such a significant shrink is even indicated, in
lieu of trim. Isn't it sufficient to just trim on logout, thus
returning unused blocks to the underlying filesystem?
I agree with you. In Fedora 35, and the default is ext4+luks+trim
which provides the same results. However I remember that in the past the
default
was btrfs+luks+shrunk. I think that something is changed i.
However, I want to provide do the systemd folks a suggestion ho change
the code.
Even a warning like: "it doesn't work that because this, please drop it"
would be sufficient.
Out of curiosity (see other thread on the systemd list about this), what
it the current recommendation (by systemd/btrfs folks rather then Fedora
defaults) for homed machine partitioning?
I'd probably recommend Btrfs with the /home subvolume set with
nodatacow if you're going to use loops of LUKS backed Btrfs homedir
images. The individual Btrfs loops will have their own COW anyway.
Otherwise, the Fedora defaults for Btrfs should be sufficient.
Thought I'd wait for Fedora 36 to be released with everything I need to
test this setup.
Fell at the first hurdle of transferring my data in!
I transferred a subset of my data (240Gb) onto an external disk and used:
homectl with colin -- rsync ...
The transfer worked but the colin.home file grew to 394Gb. Only about
184Gb used (I presume due to compression).
Ultimately, this was then unmounted and while it said it could shrink
the filesystem with a "Ready to..." message this either didn't happen or
the backing file wasn't shrunk to match it. I did receive a message later
I'm not sure now where it's at with recovery but as nothing is strictly
needed to make this work, I think I'll leave my playing with homed there
for now and try again at some later date.
I love the whole idea but it's still a bit to bleeding edge and quirky
for my daily driver just yet!
I've attached various logs in case they are useful (will post separately
if the list removes this!)
Cheers
Col
