I commented out partprobe and everything seems to work just fine. *If someone has experience with why this is very bad please advise. Make sure you know about http://tracker.ceph.com/issues/13833 also. *ps we are running btrfs in the test jig and had to add the "-f" to the btrfs_args for ceph-dis

Re: [ceph-users] double rebalance when removing osd

If I’m not mistaken, marking an osd out will remap its placement groups temporarily, while removing it from the crush map will remap the placement groups permanently. Additionally, other placement groups from other osds could get remapped permanently when an osd is removed from the crush map. I

[ceph-users] Ceph Architecture and File Management

Hi, I'm looking to create a Ceph storage architecture to store files, I'm particularly interested in the metadata segregation so would be implementing the Ceph Storage Cluster to start, with CephFS added once done. I'm wondering what the best approach to storing data would be, for example, conside

Sometimes my ceph osd tree output is wrong. Ie. Wrong osds on the wrong hosts ? Anyone else have this issue? I have seen this at Infernalis and Jewell. Thanks Wade ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi

Re: [ceph-users] Any suggestion to deal with slow request?

Hi Robert, Thank you for the prompt response. The OSDs are built on XFS and the drives are Intel SSDs. Each SSD is parted into two partitions, one is for journal, the other is for data. There is no alignment issue for the partitions. When slow request msg is outputted, the workload is quite

Re: [ceph-users] KVM problems when rebalance occurs

Hi, How did you benchmark? I would recommend to have a lot of mysql with a lot of innodb tables that are utilised heavily. During a recover you should see the latency rise at least. Maybe using one of the tools here https://dev.mysql.com/downloads/benchmarks.html Regards, Josef On 7 Jan 2016 16:

Re: [ceph-users] ceph osd tree output

Hi, Do you have by any chance disabled automatic crushmap updates in your ceph config? osd crush update on start = false If this is the case, and you move disks around hosts, they won't update their position/host in the crushmap, even if the crushmap does not reflect reality. Regards, Mart
