*Smoke* and *pacific-p2p *are approved; still working through some failures in *upgrade/octopus-x,* which I'll have ready soon. As for rados, I have summarized the suite and passed the results to Neha. In my eyes it looks good, but I want to leave final approval to Radek and/or Neha. smoke

[ceph-users] Re: [multisite] Resetting an empty bucket

Hi Yixin, This sounds interesting. I kind of suspect that this feature requires some more conceptual design support. Like, at a high level, how a bucket's "zone residency" might be defined and specified, and what policies might govern changing it, not to mention, how you direct things

[ceph-users] [multisite] Resetting an empty bucket

Hi folks, Armed with bucket-specific sync policy feature, I found that we could move objects of a bucket between zones. It is migration via sync followed by object removal at the source. This allows us to better utilize available capacities in different clusters/zones. However, to achieve

Hi Fabian, Thank you for your prompt response. It's crucial to understand how things work, and I appreciate your assistance. After replacing the switch for our Ceph environment, we experienced three days of normalcy before the issue recurred this morning. I noticed that the TCP in/out became

Assuming size=3 and min_size=2 It will run degraded (read/write capable) until a third host becomes available at which point it will backfill the third copy on the third host. It will be unable to create the third copy of data if no third host exists. If an additional host is lost the data will

That one talks about resilvering, which is not the same as neither ZFS scrubs nor ceph scrubs. The commit I linked is titled "Sequential scrub and resilvers". So ZFS scrubs are included. ___ ceph-users mailing list -- ceph-users@ceph.io To

[ceph-users] Ceph recovery

Hi, When creating a ceph cluster, a failover domain is created, and by default it uses host as a minimal domain, that domain can be modified to chassis, or rack, ...etc. My question is : Suppose I have three osd nodes, my replication is 3 and my failover domain is host, which means that each

[ceph-users] RBD mirroring, asking for clarification

Hi, When using rbd mirroring, the mirroring concerns the images only, not the whole pool? So, we don't need to have a dedicated pool in the destination site to be mirrored, the only obligation is that the mirrored pools must have the same name. In other words, We create two pools with the same

[ceph-users] Block RGW request using Lua

Hello everyone, I've started playing with Lua scripting and would like to ask If anyone knows about a way to drop or close user request on the prerequest context. I would like to block creating buckets with dots in the name, but the use-case could be blocking certain operations, etc. I was

[ceph-users] Re: Deep-scrub much slower than HDD speed

Hi all, Scrubs only read data that does exist in ceph as it exists, not every sector of the drive, written or not. Thanks, this does explain it. I just discovered: ZFS had this problem in the past: *

[ceph-users] Re: Deep-scrub much slower than HDD speed

Hi Marc, thanks for your numbers, this seems to confirm the suspicions. Oh I get it. Interesting. I think if you will expand the cluster in the future with more disks you will spread the load have more iops, this will disappear. This one I'm not sure about: If I expand the cluster 2x, I'll

[ceph-users] Re: How can I use not-replicated pool (replication 1 or raid-0)

I think you misunderstood Janne's reply. The main statement is at the end, ceph is not designed for an "I don't care about data" use case. If you need speed for temporary data where you can sustain data loss, go for something simpler. For example, we use beegfs with great success for a burst
