Re: [ceph-users] Ceph Recovery

Hi Wido, Yes you are right. After removing the down OSDs, reformatting and bring them up again, at least until 75% of total OSDs, my Ceph Cluster is healthy again. It seem there is high probability of data safety if the total active PGs same with total PGs and total degraded PGs same with total un

[ceph-users] Help with seemingly damaged MDS rank(?)

We have a rather urgent situation, and I need help doing one of two things: 1. Fix the MDS and regain a working cluster (ideal) 2. Find a way to extract the contents so I can move it to a new cluster (need to do this anyway) We have 4 physical storage machines: stor1, stor2, stor3, stor4 The MDS

Re: [ceph-users] Starting a cluster with one OSD node

Hi Alex, Thank you for your response! Yes, this is for a production environment... Do you think the risk of data loss due to the single node be different than if it was an appliance or a Linux box with raid/zfs? Cheers, Mike > On May 13, 2016, at 7:38 PM, Alex Gorbachev wrote: > > > >> On

Re: [ceph-users] Starting a cluster with one OSD node

Hi Christian, Thank you, I know what I am asking isn't a good idea... I am just trying to avoid waiting for all three nodes before I began virtualizing our infrastructure. Again thanks for the responses! Cheers, Mike > On May 14, 2016, at 9:56 AM, Christian Balzer wrote: > > On Sat, 14 May

[ceph-users] How to remove a placement group?

Hi all, I’m currently having trouble with an incomplete pg. Our cluster has a replication factor of 3, however somehow I found this pg to be present in 9 different OSDs (being active only in 3 of them, of course). Since I don’t really care about data loss, I was wondering if it’s possible to get

Re: [ceph-users] Help with seemingly damaged MDS rank(?)

One of the issues was a different version of ceph on the nodes. They are now all back to version 9.0.2 and things are looking a bit better. We've had some help from a ceph engineer, and the OSD's are now all up and running: [root@stor2 ceph]# ceph osd tree ID WEIGHTTYPE NAMEUP/
