Re: [ceph-users] Centos 7 OSD silently fail to start

I am using the long form and have it working. The one thing that I saw was to change from osd_host to just host. See if that works. On Feb 25, 2015 5:44 PM, "Kyle Hutson" wrote: > I just tried it, and that does indeed get the OSD to start. > > However, it doesn't add it to the appropriate place

Have you checked firewall or made sure you created the mount for the osd correctly? Did you check the osd.43 log? On Mar 8, 2015 3:58 PM, "Jesus Chavez (jeschave)" wrote: > Hi all, I had issues with a stuck PGs so I decided to star over and > delete 1 OSDs host that was causing the issues I re

[ceph-users] Replication question

I am looking into how I can maximize my space with replication, and I am trying to understand how I can do that. I have 145TB of space and a replication of 3 for the pool and was thinking that the max data I can have in the cluster is ~47TB in my cluster at one time..is that correct? Or is there

Re: [ceph-users] HEALTH_WARN too few pgs per osd (0 < min 20)

I believe you are getting this message because you dont have any pools, and placement groups. Thats what the message is telling you that you have less (0) than the minimum amount(20)..once you create the pools and placement groups verify if you are still receiving this message. On Mar 15, 2015 11:

Re: [ceph-users] Terrible iSCSI tgt RBD performance

Also what are you getting locally on your filesystem? Looking at the specs for a 840 pro, ~520MBps and based on the numbers you stated earlier your arent getting close to that so there might be a problem at the server. Once you start seeing better numbers at the local, then retry your iscsi target

Your error looks to be the mountpoint or the option in your ansible playbook... Are you sure its running in order? Can you mount a different directory using the commands? On Mar 17, 2015 6:24 PM, "Florent B" wrote: > Hi everyone, > > My problem is about ceph-fuse & Ansible, I first post here to

Re: [ceph-users] ceph-fuse unable to run through "screen" ?

Check tty session for remote execution. Could explain why it worked when you were logged in. Possibly ansible is running mount command without tty. Check your settings for that user and see if they required to have tty to make remote calls such as mount. On Mar 18, 2015 5:42 AM, "Florent B" wro

Re: [ceph-users] Issue with free Inodes

You could fix this by changing your block size when formatting the mount-point with the mkfs -b command. I had this same issue when dealing with the filesystem using glusterfs and the solution is to either use a filesystem that allocates inodes automatically or change the block size when you build
