No, we only think about introduceing to us project. Yes, I know, other way ceph you can change rebuilding parameters, but I think when you have a lot of drives, your storage always will rebuild. But, If you use raid controller and array storages it will be next situation with rebuilding system

we have over 7 nodes with: Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz 10gbit/s network adapter at this moment we are have 10ssd for 800gb by intel, and running over 200 customers virtual servers All ssd connected to ceph cluster and we have some trouble, when cluster rebuild. First if you have...

How many do you want have virtual machines? What about configurations this virtual machines? I have bad experience with 200 virtual machines and 30 osd drives. Now we are using only ssd drives on ceph cluster.

I have next version gluster on my server: rpm -qa|grep gluster glusterfs-libs-3.7.11-2.el6.x86_64 glusterfs-3.7.11-2.el6.x86_64 glusterfs-api-3.7.11-2.el6.x86_64 glusterfs-fuse-3.7.11-2.el6.x86_64 glusterfs-client-xlators-3.7.11-2.el6.x86_64 glusterfs-server-3.7.11-2.el6.x86_64...

Does proxmox has update this problem? https://security-tracker.debian.org/tracker/CVE-2016-3710

yes, that's why we have big problem with degradation performance, more different block size in virtual machine and zvols.

Could you run this command? fio –name fio_test_file –direct=0 –rw=randwrite –bs=4k –size=20G –numjobs=16 –time_based –runtime=180 –group_reporting similar block size on zfs and internal fs of virtual machine very important, if you have different block size, you will have a lot of over commit...

think about block-size on zfs pool and internal vm fs, example: freebsd default block 32kb, ext4 4k, but zfs pool 128kb.

we have 30drives and performance very degraded, that's why we chose replace all disk to ssd. ceph is very stable system, I don't know what need do to kill ceph cluster.

sometimes we see this problem and connected this to problem with cheap network adapters, which have only two msix lines.

Hi All. I have small question about proxmox. What are you thinking about ceph with in different drives, I want mixing 1TB SSHD with 800GB SSD Intel. What are you think this will be working fine? At this moment I have 5nodes with 30drives 1TB, but I have problem with drive performance, that why...

Interesting question about zfs and trim Did proxmox support trim on zfslinux for ssd drives?

Could you help me with change global options in ceph.conf? I would like to add: osd recovery op priority = 2 osd max backfills = 1 osd recovery max active = 1 osd recovery threads = 1 and how I can apply new settings without reboot ceph and disconnect clients?

I have some small problem with cluster on proxmox 4. First story: when we create cluster https://pve.proxmox.com/wiki/Proxmox_VE_4.x_Cluster we do hp2# pvecm add IP-ADDRESS-CLUSTER where IP-ADDRESS-CLUSTER it's ip address first node on cluster. can I reinstall first node on cluster and add...

you'll be lucky if you can do it :) but, I have big problem with one node, when I upgraded from 3.4 to 4.1.

But zfs can't possible on cluster storage between nodes

thanks about zfs swap, it's intresting, I will try disable swap on Mondey.

Backup storage made glusterfs. I don't have any messages in syslog, but only a litle messages in kernel.log I can reproduce every-time when I do backup task from console or api query

Nobody can't help me with this problem?
