[ceph-users] Operating System Upgrade

Hi Everyone, I am upgrading the nodes of my ceph cluster from centos 6.6 to centos 7.1. My cluster is currently running Firefly 0.80.10. I would like to not reformat the OSD Drives and just remount them under Centos 7.1. Is this supported? Should it work? When we upgrade to Centos 7.1 we wi

[ceph-users] Ceph file system is not freeing space

I am trying to figure out why my Ceph file system is not freeing space. Using Ceph 9.1.0 I created a file system with snapshots enabled, filled up the file system over days while taking snapshots hourly. I then deleted all files and all snapshots, but Ceph is not returning the space. I left the c

[ceph-users] data balancing/crush map issue

Hi, I have a Ceph cluster running on 0.80.10 and I'm having problems with the data balancing on two new nodes that were recently added. The cluster nodes look like as follows: 6x OSD servers with 32 4TB SAS drives. The drives are configured with RAID0 in pairs, so 16 8TB OSD's per node. New ser

[ceph-users] Number of buckets per user

Hi! Maybe I am missing something obvious, but is there no way to quickly tell how many buckets an RGW user has? I can see the max_buckets limit in radosgw-admin user info --uid=x, but nothing about how much of that limit has been used. To be clear: I do not care what they are called, or what

Re: [ceph-users] Problem with infernalis el7 package

did you recreate new rpms with same version/release? it would be better to make new rpms with different release (e.g. 9.2.0-1). we have snapshotted mirrors and nginx caches between ceph yum repo and the nodes that install the rpms, so cleaning the cache locally will not help. stijn On 11/11/2015
