    Why doesn't btrfs + cryptsetup count in your tables? I'm using it right now.

    Stratis does have limitations that using the tools individually do not (as is the artical of this thread implies)






    Ceph Btrfs zfs lvm+ stratis
    snapshot y y y y
    raid0 y y y y
    raid1 y y y y
    raid10 y y y y
    raid5 y unstable y y
    raid6 y unstable y y
    raid7 y y
    online raid change y y n n
    IO isolation groups y
    online growth y y y y
    online shrink y y n y
    read cache y n y (l2arc) y
    write cache y n y (slog) y
    encryption y n y y (cryptsetup)
    compression y y y y (lvmvdo)
    diff sync y y y y (lvmsync)
    checksums y y y y (integritysetup)
    dedup y y (offline) y n (dm_dedup)
    resilvering y y y n
    skip empty blocks on repair y y y y
    remote cache y n n y (dm_cache)
    continuous availability y n n n
    reflink n y n n
    score 21 17 17 16 ?
    Changes: Ceph can online add any number/combination of shards/replicas which is the equivalent of any raid level.

    remote cache y n n y (dm_cache)
    continuous availability y n n n
    reflink n y n N/A
    score 15 15+2 17 15 ?

    Changes:
    - all: add row raid5/raid6/raid7 (triple parity)
    - btrfs: change dedup from 'n' to 'y offline'
    - all: add row IO isolation capability via cgroups2
    - all: add row reflink
    - all: add row resilvering

    Note1: it is not considered to stacks btrfs over device mapper; otherwise BTRFS would have the encryption
    Note2: stratis is based on lwm/device mapper. So everything we can joint the last two columns

    Has anyone done any benchmarks on Stratis lately? I attempted to use it in a continuous integration test environment near the 1.0 release but performance was an order of magnitude+ worse than ZFS with a single snapshot. Needless to say, that system is using ZFS.

    Is there an up to date feature comparison with BTRFS?

    Does it have data checksums, deduplication, send/receive, efficient repair (only worrying about block that actually have data)?

    Their FAQ pages has statements like
    "How does Stratis handle hard drive or other hardware failures?
    For current releases of Stratis it doesn’t. In fact if you create a Stratis pool with multiple devices you increase the risk of data loss as you now have multiple devices which are required to be operational to access the data." -- https://stratis-storage.github.io/faq/

    "Stratis continues making great progress" hm what progress is that then? Last i checked their site, it gave me the impression that its big "feature" is that its written in rust. Everything it does is creating thin provisioning volumes.
