Hi, While not necessarily CephFS specific - we somehow seem to manage to frequently end up with objects that have inconsistent omaps. This seems to be replication (as anecdotally it's a replica that ends up diverging, and it's at least a few times something that happened after the osd that held

Thanks Greg. I thought it was impossible when I reported 34MB for 52 million files. On Jul 19, 2017 1:17 PM, "Gregory Farnum" wrote: > > > On Wed, Jul 19, 2017 at 10:25 AM David wrote: > >> On Tue, Jul 18, 2017 at 6:54 AM, Blair Bethwaite < >>

Hi, thanks for your sharing:-) So I guess you have not put cephfs into real production environment, and it's still in test phase, right? Thanks again:-) 发件人: Дмитрий Глушенок [mailto:gl...@jet.msk.su] 发送时间: 2017年7月19日 17:33 收件人: 许雪寒 抄送: ceph-users@lists.ceph.com 主题: Re: [ceph-users] How's

Is there anyone else willing to share some usage information of cephfs? Could developers tell whether cephfs is a major effort in the whole ceph development? 发件人: 许雪寒 发送时间: 2017年7月17日 11:00 收件人: ceph-users@lists.ceph.com 主题: How's cephfs going? Hi, everyone. We intend to use cephfs of Jewel

Re: [ceph-users] 答复: How's cephfs going?

We have a cephfs data pool with 52.8M files stored in 140.7M objects. That translates to a metadata pool size of 34.6MB across 1.5M objects. On Jul 18, 2017 12:54 AM, "Blair Bethwaite" wrote: > We are a data-intensive university, with an increasingly large fleet > of

Re: [ceph-users] 答复: How's cephfs going?

We are a data-intensive university, with an increasingly large fleet of scientific instruments capturing various types of data (mostly imaging of one kind or another). That data typically needs to be stored, protected, managed, shared, connected/moved to specialised compute for analysis. Given the

Re: [ceph-users] 答复: How's cephfs going?

No problem. We are a functional mri research institute. We have a fairly mixed workload. But, I can tell you that we see 60+gbps of throughput when multiple clients are reading sequencially on large files (1+GB) with 1-4MB block sizes. IO involving small files and small block sizes are not very

Hi, thanks for the advice:-) By the way, may I ask what kind of business you are using cephFS for? What's the IO pattern of that business? And which version of ceph are you using? If this involves any business secret, it's really understandable not to answer:-) Thanks again for the help:-)

Re: [ceph-users] 答复: How's cephfs going?

I work at Monash University. We are using active-standby MDS. We don't yet have it in full production as we need some of the newer Luminous features before we can roll it out more broadly, however we are moving towards letting a subset of users on (just slowly ticking off related work like putting

[ceph-users] 答复: How's cephfs going?

Hi, thanks for the quick reply:-) May I ask which company are you in? I'm asking this because we are collecting cephfs's usage information as the basis of our judgement about whether to use cephfs. And also, how are you using it? Are you using single-mds, the so-called active-standby mode? And
