Intel recently announced that it will no longer provide 3D Xpoint DIMMs, so how will this affect DAOS?

Hello, Everyone! Now all update/fetch requests of pools are in sched_info->si_fifo_list. If a pool request exceeds req_kick_limit, will it also block other pool requests? thanks!

I think a lease mechanism is needed, and modifications cannot be made before the server lease expires

If a DTX starts after this copy has a network partition, this replica will not have a record of this DTX. If the client reads the data modified by this DTX after this DTX is committed, it will get out

DAOS uses two-phase commit to ensure consistency between replicas. According to "src/vos/readme.md", read requests can be sent to any replica, but if this replica server has a network partition（the cl

While a file is opened by one client, can other clients delete the file? If it cannot be deleted, how is this guaranteed? Thanks~

Hi~, I have two questions about DFS metadata: 1. When the client opens a file or directory, will it check the permissions for each directory on the path, or will it only check at dfs_mount()? 2. Will

So the leader is the coordinator of 2PC?

hi～ There are two different leader election rules in the code comments and in the VOS readme, as shown below. Does the leader described by the two have the same meaning? According to my understanding,

hi~ I have some questions about DTX. In DAOS, DTX is used to implement distributed transactions and ensure replica consistency. As far as I know, for a transaction in a prepared state in a non-leader

T3 starts before T1, so T3 can obtain a timestamp less than T1. T1 has not yet started when T3 is read, so there will be no uncertain reading When T1 writes C1, it does not check the read timestamp sm

I found that the concurrency control of DAOS is similar to CockroachDB, but the following situations may occur in CockroachDB according to jepsen analysis (https://jepsen.io/analyses/cockroachdb-beta-
