Slow, buggy and resource hungry. Faster spdk-based engine rewrite has been on the way for like 7 years now


One cool feature of ceph is reed solomon erasure coding, myastor only does replication if storage efficiency is important

4+2 Erasure Coding has only half the storage overhead of 3x replication but the same fault tolerance

Also re spdk

RS and XOR EC are definitely useful features for an object store that's storing from like tens of petabytes to exabytes worth of data but for a remote block device with a typical size up to a couple dozen terabytes I'm not so sure. Thanks for the link I will check it out

Edit: skimmed it, classic AI "analysis" - totally ignores all the crap io_uring went through


Buggy hasn't been my experience and the overhead should get smaller as storage grows. In any case, you'd get extra features such as S3, which would otherwise require running another service
