In my opinion, I would not say that DAOS has tiers. It does support a configuration for small writes landing in PMEM and then a later aggregation service will batch them into the NVME. However, there

Hello Chuck Pool extend might migrate the data to the new pool target, then the original data will be delete asynchronous, so those space might be reclaimed a few mins later if the system is not

# dmg pool query kiddie Pool 700bf1b6-38b8-467e-9f91-7131138210ba, ntarget=32, disabled=0, leader=0, version=18 Pool space info: - Target(VOS) count:32 - Storage tier 0 (SCM): Total size: 60 GB

As I was going through the documentation reading about the storage pools I saw the diagram that shows storage pool 1, 2, and 3 all a combination of SCM PMEM or NVMe, but I couldn’t find any detail

Thanks! Those were well hidden. Let us take a look and we’ll follow-up with more questions if we have any. Best, Jay

Adrian, I don’t think this link is correct😊 Jay, we have the quickstart guides for RHEL/clones and SuSE (seehttps://docs.daos.io/v2.0/QSG/setup_rhel/) and the more detailed admin guide

Hi Jay, Have you seen the documentation(s) at https://docs.daos.io/v2.0/QSG/ ? Do you want something beyond that? cheers adrianj -- Tel: +44 131 6506470 skype: remoteadrianj The University of

The documentation on the site is minimally helpful. Is there a good guide for installing DAOS 2.0? Our context: We have 4 nodes with Optane PMEM devices and we want to make a mini-install that

Hello Chuck, Could you please run `dmg pool query` on the pool and show the results, this will give you a bit more info on pool usage. Regards, Tom

I've been experimenting with extending a pool but don't quite understand the results. Any insights would be most appreciated. The cluster is running with DAOS v2.0.2 and consists of a client and a

Hi everyone: Recently, i use daos array interface to do some test, i found that the client's performance would be improved by increasing the client’s thread num. And the server does not reach the

Right, that’s probably something could be improved in the future. Maybe we could move the blobstore creation from io engine (on first start) to control plane (on storage format?). Thanks for

Hi everyone： In create_bio_bdev function， if load_blobstore is failed， DAOS would init it. I'm a little worry about it. Whether there is a possibility of an exception when creating bdev or

Yes, libioil works in conjunction with DFuse and allows the interception of POSIX I/O calls.

Try to explicitly set the object class for files and directories – the defaults are not providing the best performance for mdtest-like workloads: --dfs.oclass=S1 --dfs.dir_oclass=SX

Hi, Without data protection, SX (striping across all storage targets) and S1 (using only a single storage target) are your two main options. With replication or erasure coding, there are more
