Hi, That’s great. I’ll push the user option setting ASAP. About the quotas, you mean Windows quotas or Ceph quotas? Regars, Lucian From: Jake Grimmett<mailto:jog@mrc-lmb.cam.ac.uk> Sent: Thursday, February 25, 2021 11:37 AM To: Lucian Petrut<mailto:lpetrut@cloudbasesolutions.com>; dev@ceph.io<mailto:dev@ceph.io> Subject: Re: Windows port Hi Lucian, So I've now copied 32TB of data from a Windows server to our test ceph cluster, without any crashes. Average speed over one 16TB copy was 468MB/s, i.e. just under 11 hours to transfer 16TB, with a data set that has 1,144,495 files. The transfer was from Windows 10 server (hardware RAID) > Windows 10 VM (with the cephfs driver installed) > cephfs test cluster. If you can get the user option working, I'll put the driver on a physical Windows 10 system, and see how fast a direct transfer is. One other thing that would be useful, is over-quota error handling. If I try writing and exceed the quota, the mount just hangs. If I increase the quota, the mount recovers, but it would be nice if we had a quota error in Windows. Test cluster consists of 6 Dell C2100 nodes, bought in 2012. Each has 10 x 900GB 10k HDD, we use EC 4+2 for the cephfs pool, metadata is on 3 x NVMe. Dual Xeon X5650, 12 threads, 96GB RAM, 2x10GB bond. Ceph 15.2.8, Scientific Linux 7.9. best regards, Jake On 2/23/21 11:49 AM, Lucian Petrut wrote:
Hi,
That’s great, thanks for the confirmation.
I hope I’ll get to push a larger change by the end of the week, covering the user option as well as a few other fixes.
Regards,
Lucian

Hi Lucian,
Good news - your fix works; I was able to write 7TB from a Windows 10 VM to cephfs last night.
I'll carry on testing the Windows client with large workloads using robocopy.
thanks again for working on this, a cephx "user" option should provide the core requirements we need for a usable system :)
best regards,
Jake
