Re: [ceph-users] osd prepare 10.1.2

Hi Michael, The partprobe issue was resolved for me by updating parted to the package from Fedora 22: parted-3.2-16.fc22.x86_64. It shouldn't require any other dependencies updated to install on EL7 varieties. http://tracker.ceph.com/issues/15176 regards, Ben On Thu, Apr 14, 2016 at 12:35

Yep! This is fixed in the jewel and master branches now, but we're going to wait until the next rc (or final release!) to push official packages for it. In the meantime, you can install those from our gitbuilders following the instructions at

Thank you for the advice. Our crush map is actually setup with replication set to 3, and at least one copy in each cabinet, ensuring no one host is a single point of failure. We fully intended on performing this maintenance over the course of many week, one host at a time. We felt that the

Re: [ceph-users] Advice on OSD upgrades

Sadly, this is not an option. Not only are there no free slots on the hosts, but we're downgrading in size for each OSD because we decided to sacrifice space to make a significant jump in drive quality. We're not really too concerned about the rebalancing, as we monitor the cluster closely

Hi, that's how I did it for my osd's 25 to 30 (you can add as much as osd numbers you like as long you have free space). First you can reweight the osd's to 0 to move their copies to other osd's for i in {25..30}; do ceph osd crush reweight osd.$i done and have to wait until it's done (when
