New release: stratisd 1.0.1
by Andy Grover
Hi all,
stratisd 1.0.1 is a bugfix release. The one user-visible change is that
the directory that Stratis places symlinks to filesystems has changed
from /dev/stratis to /stratis. This lets Stratis work better in
conjunction with systemd, and also happens to be similar to ZFS's behavior.
Along with that, a number of critical bugs were fixed:
* creating a snapshot with "stratis filesystem snapshot" fails with
"xfs_db: command not found" due to PATH issue (#1251)
* Adding a device to a full pool does not allow a user to immediately
create new FS (#1234)
* Limit what we allow in pool names & filesystem names (#1263)
* creating snapshot does not check for name conflict (#1289)
* stratisd fails when cache grows to ~40TiB (#1292)
* Corrupt fs after tying to rsync some 90G on a 150G single fs pool (#1242)
* Running out of space during FS creation results in bad state as dm
table is left behind (#1254)
These changes should mean that Stratis is no longer *guaranteed* to eat
your data. :-) Please give it a spin. Shortlog follows.
Thanks -- Regards -- Andy

Basic questions
by Matthew Miller
I'm about to buy a new desktop PC. (I want a system with AMD open source
graphics.) Because, hey, big case, I've got the ability to put in multiple
disks. Soooo, I was thinking maybe I'd play with stratis, because dogfood
and all that. This leads me to some naive questions:
* Can I boot to stratis? That is, / on stratis? Or do I need a basic system
and then use stratis for data volumes like /home, /srv?
* I see the new version allow a cache disk. Is two mirrored spinning rust
disks and a SSD cache a reasonable setup for general use?
I guess even if the answer to the first question is "no", I could, say, use
20GB of an SSD for / and /usr and make the rest a stratis cache?

Stratis 1.0 released
by Andy Grover
Hi all,
I'm pleased to announce the release of stratisd and stratis-cli 1.0.0.
This version indicates on-disk metadata and command-line interface
stabilization, and an indicator that Stratis is ready for a wider scope
of evaluation and testing.
The shortlong is below, showing a significant shunk of work from the
entire core team -- Todd, Mulhern, Tony, thanks for pulling so hard to
get the last minute issues resolved!
The official release notes are here:
https://stratis-storage.github.io/relnotes/relnotes-1.0.html
Stratis 1.0 will be available soon for Fedora, and we invite you to kick
the tires and tell us what you think. I'd still exercise restraint when
putting irreplaceable data on it just yet.
Now would also be a great time for other distros to consider packaging
Stratis. Of course, it depends on Python 3 and Rust support, but if
those are available then packaging should be doable. Please feel free to
get in touch offline if there's anything I can do to make packaging easier.
