[ceph-users] Bad IO performance CephFS vs. NFS for block size 4k/128k

Hello! I'm validating IO performance of CephFS vs. NFS. Therefore I have mounted the relevant filesystems on the same client. Then I start fio with the following parameters: action = randwrite randrw blocksize = 4k 128k 8m rwmixreadread = 70 50 30 32 jobs run in parallel The NFS share is

[ceph-users] Defining quota in CephFS - quota is ignored

Hello! Based on the documentation for defining quotas in CephFS for any directory (http://docs.ceph.com/docs/master/cephfs/quota/), I defined a quota for attribute max_bytes: ld4257:~ # getfattr -n ceph.quota.max_bytes /mnt/ceph-fuse/MTY/ getfattr: Removing leading '/' from absolute path names

Re: [ceph-users] Mounting pool, but where are the files?

Understood. Would you recommend to have a dedicated pool for the data that is directly written using librados and another pool for the filesystem (CephFS)? 24. Juli 2017 19:46, "David Turner" schrieb: You might be able to read these objects using s3fs if you're using a RadosGW. But

Re: [ceph-users] Writing data to pools other than filesystem

Hello! My understanding is that I create on (big) pool for all DB backups written to storage. The clients have restricted access to a specific directory only, means they can mount only this directory. Can I define a quota for a specific directory, or only for the pool? And do I need to define
