New release: stratisd 1.0.1
by Andy Grover 31 Oct '18

31 Oct '18

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 stratisd 1.0.1: Andy Grover <agrover(a)redhat.com> (9): add rpm specfile for automated copr builds fix copr specfile fix copr specfile 2 fix copr specfile 3 docs/RELNOTES-0.5.md moved to docs repo Try using BufWriter to speed up some tests README: Tell people how to get the correct rustfmt version Fix clippy Call udev_settle() after failed fs create Todd Gill <tgill(a)redhat.com> (7): Add validation of stratis pool and filesystem names Add unit test for validate_name() Increase the FILESYSTEM_LOWATER to 4x the DATA_LOWATER Increase the default DATA_EXPAND_SIZE to max(8 GiB, current_dirty_mem) Increase the DATA_LOWATER to 2 GiB Increase META_LOWATER_FALLBACK to MetaBlocks(1024) Update test_thinpool_expand to handle DATA_LOWATER > INITIAL_DATA_SIZE Tony Asleson <tasleson(a)redhat.com> (6): We are @ major ver. 1 Change symlink directory Correct release version & link Use more specific assert tests/client-dbus: Add test for Snapshot name Ensure snapshot name does not exist mulhern <amulhern(a)redhat.com> (19): Really run clippy Fix two clippy lints Fix some deeper clippy errors Avoid overlapping ranges Omit redundant nested if in stratisd.rs Omit redundant field names Don't match events by reference Omit some matches by reference Wipe only the first 4K of each metadata device Invoke xfs_db directly Use "-x", expert flag Call thin pool's check method after adding data devs Eliminate Backstore::add_blockdevs Do not remove pool from engine if it can't be destroyed Temporarily allow a Travis failure Revert "Temporarily allow a Travis failure" Destrengthen existence check Do not compare fs_objects against "/" Make a method to remove specified blockdevs

Hi all, As a process note, I wanted to mention I've created two projects for future releases: Stratis 1.1 https://github.com/orgs/stratis-storage/projects/2 The next release with new features. Target date not yet set. Stratis 1.0.1 https://github.com/orgs/stratis-storage/projects/3 Bugfix release for 1.0. Target date.. end of the month? Only two issues so far, but I believe there are a couple more incoming. Thanks -- Regards -- Andy

Basic questions
by Matthew Miller 02 Oct '18

02 Oct '18

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? -- Matthew Miller <mattdm(a)fedoraproject.org> Fedora Project Leader

Stratis 1.0 released
by Andy Grover 01 Oct '18

01 Oct '18

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. stratisd 1.0.0: Andy Grover <agrover(a)redhat.com> (18): Use thindev status for Filesystem::used() Use dm-rs 0.25.0 Rewrite destroy_filesystem to fail properly if fs is mounted Do not abort setting up filesystems if one fails Add TODO around fs duplicate id/uuid handling Set throttling in all directories under /sys/fs/cgroup/blkio Rename *current_capacity() to size() Replace "capacity" in method names with "size" and "allocated" Remove backstore.available() in favor of .available_in_{cap, backstore}() Change Blockdev::total_size() to ::size() Update README.md with alternatives to using GitHub Destroy thindev if create_fs() fails Add versions to Sigblock, metadata header, and metadata Map Engine errors to DbusErrorEnum::ERROR instead of INTERNAL_ERROR Remove DbusErrorEnum::NIX_ERROR Remove DbusErrorEnum::IO_ERROR version 1.0.0 Update data.py for new supported signals Todd Gill <tgill(a)redhat.com> (8): Fix spelling of specified Remove FilesystemUsedChanged event Export the pool state as a dbus property Send PoolStateChanged event to listeners on state change Extend PoolState to track the DM state of a pool Add PoolExtendState to Pool for tracking the extention of meta/data devs Add PoolExtendStateChanged to dbus Publish pool FreeSpaceState changes on dbus Tony Asleson <tasleson(a)redhat.com> (11): Ignore incomplete udev entries during enumeration device_as_map: Remove expect(s) Bug fix: correct is_stratis_device find_all: Remove redundant check if Stratis device Remove warn! for pool already known devlinks: Do not return results devlinks: Add setup_pool_devlinks function Setup symbolic links on event driven pool bringup remove 'force' flag Remove 'force' from dbus client tests Make test/README.md a link mulhern <amulhern(a)redhat.com> (10): Refactor calc_lowater to avoid unnecessary duplication Factor out a value that is used in two subsequent expressions Remove a FIXME Add a method to get a StratBlockDev from a StratPool Unpublicize a few things that shouldn't be publicized Update to devicemapper-rs v0.26.0 Use display rather than description for DmError::Core errors Change specification of variable length metadata Check value of DM_MULTIPATH_DEVICE_PATH When setting up the data tier use a reasonable size stratis-cli 1.0.0: Andy Grover <agrover(a)redhat.com> (2): Update _data.py for API changes version 1.0.0 Tony Asleson <tasleson(a)redhat.com> (4): Move add-data & add-cache from blockdev -> pool Update man page: add-data & add-cache move Update tests: add-data & add-cache move Remove 'force' option mulhern <amulhern(a)redhat.com> (2): Expand an error diagnosis to include the wider range of possibilities Update StratisdErrors enum for stratisd changes devicemapper 0.25.0 and 0.26.0: Andy Grover <agrover(a)redhat.com> (3): Change teardown methods to take &mut self version 0.25.0 version 0.26.0 mulhern <amulhern(a)redhat.com> (1): Use primitive type-based chaining mechanism
