Re: [ceph-users] Crushmap and failure domains at rack level (ideally data-center level in the future)

I think I was able to figure out what happened. Some of my rgw pools had a min_size of 1 and some had a min_size of 2. I am not certain how this happened but my theory is I must have had at least one of the pools created before I modified the crushmap rules. After the rule was modified new

Sorry for the delay but ceph osd pool get min_size returns 1. Where does this value come from? Get Outlook for iOS On Tue, Oct 23, 2018 at 5:47 PM -0700, "Bastiaan Visser" mailto:bvis...@flexyz.com>> wrote: Something must be wrong, since you have min_size 3 the pool

Re: [ceph-users] RGW: move bucket from one placement to another

Resharding a bucket won't affect the data in the bucket. After you change the placement for a bucket, you could update where the data is by re-writing all of the data in the bucket. On Thu, Oct 25, 2018 at 8:48 AM Jacek Suchenia wrote: > Hi > > We have a bucket created with LocationConstraint

Just an update - maybe will help others I've downloaded and ran Intel firmware update ISO Although the tool confirmed firmware was current ( no update necessary) , after I rebooted, the performance was similar with the other 3 servers Odd but.. nothing is/was making sense Steven On Thu, 25 Oct

Re: [ceph-users] Migrate/convert replicated pool to EC?

There are no tools to migrate in either direction between EC and Replica. You can't even migrate an EC pool to a new EC profile. With RGW you can create a new data pool and new objects will be written to the new pool. If your objects have a lifecycle, then eventually you'll be to the new pool

Re: [ceph-users] NVME Intel Optane - same servers different performance

Thanks for suggestion However same "bad"server was working fine until I updated firmware Now, all 4 server have the same firmware but one has lower performance I will try what you suggested though although, as I said, same server with same NVME had good performance before updating server firmware

[ceph-users] Migrate/convert replicated pool to EC?

Hi, I thought I'd seen that it was possible to migrate a replicated pool to being erasure-coded (but not the converse); but I'm failing to find anything that says _how_. Have I misremembered? Can you migrate a replicated pool to EC? (if so, how?) ...our use case is moving our S3 pool which

Re: [ceph-users] NVME Intel Optane - same servers different performance

Hello Steven, You could swap the SSDs from the hosts to see if the error is migrating. If it migrates, I would appreciate that the affected SSD simply offers less performance than the others. Possibly an RMA reason depending on what the manufacturer guarantees. If not, the system must be further

[ceph-users] RGW: move bucket from one placement to another

Hi We have a bucket created with LocationConstraint setting, so explicit_placement entries are filled in a bucket. Is there a way to move it to other placement? I was thinking about editing that data and run manual resharding, but I don't know if it's a correct way of solving this problem. Jacek
