[ceph-users] Ideas for Powersaving on archive Cluster ?

Hi, a customer has a ceph cluster which is used for archiving large amounts of video data. The cluster sometimes is not used for several days but if data is needed the cluster should be available within a few minutes. The cluster consists of 5 Servers and 180 physical seagate harddisks and was

Thanks David and Marius for your input. Can you share which versions of Ceph you've experienced this with? And what is the use-case: RGW, CephFS, RBD, mixed ... ? Is there anything special about your ceph usage ? small/large files? num osds ? Num PGs ? When was the cluster created? Thanks! dan

[ceph-users] are you using nfs-ganesha builds from download.ceph.com

Dear Ceph Users, There was a question at the CLT today about the nfs-ganesha builds at: https://download.ceph.com/nfs-ganesha/ Are people actively using those? Is there a reason you don't use the builds from https://download.nfs-ganesha.org/ (which links to the Storage SIG in the case of CentOS a

[ceph-users] RDMA Bridging? ("You don't know that you don't know")

Hey Folks, - For background, I am working with a small (home-lab) ceph cluster on a proxmox cluster. - Proxmox uses a shared cluster storage to pass configuration files around, including ceph.conf - All nodes are connected with Mellanox connectx-3 (mlx4_core) 56GbE cards connected via qsfp switc

[ceph-users] Re: Ideas for Powersaving on archive Cluster ?

If performance isn't as big a concern, most servers have firmware settings that enable more aggressive power saving, at the cost of added latency/reduced cpu power/etc. HPE would be accessible/configurable via HP's ILO, Dells with DRAC, etc. They'd want to test and see how much of an impact it made

[ceph-users] Re: are you using nfs-ganesha builds from download.ceph.com

Hi Dan, I probably have a very specific use of CEPH + nfs-ganesha but I don't use nfs-ganesha builds (from any location). The reason is that I had to patch nfs-ganesha 3.5 in order to play nicely with CEPHFS and POSIX ACLs (using VFS FSAL)... Arnaud ___

[ceph-users] Re: are you using nfs-ganesha builds from download.ceph.com

Looks like I'm installing from a package repo and not from individually downloaded packages. According to my yum repo conf, I'm pulling from mirrors.centos.org using the repo storage-nfs-ganesha-28. If that redirects elsewhere upstream, I'm not aware of it. I don't remember why I did it this wa
