Thank you for documenting your progress and peril on the ML. Luckily I only have 24x 8TB HDD and 50x 1.92TB SSDs to migrate over to bluestore. 8 nodes, 4 chassis (failure domain), 3 drives per node for the HDDs, so I’m able to do about 3 at a time (1 node) for rip/replace. Definitely taking

I hear you on time. I have 350 x 6TB drives to convert. I recently posted about a disaster I created automating my migration. Good luck On Jan 11, 2018 12:22 PM, "Reed Dier" wrote: > I am in the process of migrating my OSDs to bluestore finally and thought > I would give

Re: [ceph-users] filestore to bluestore: osdmap epoch problem and is the documentation correct?

I am in the process of migrating my OSDs to bluestore finally and thought I would give you some input on how I am approaching it. Some of saga you can find in another ML thread here: https://www.spinics.net/lists/ceph-users/msg41802.html

Dear *, has anybody been successful migrating Filestore OSDs to Bluestore OSDs, keeping the OSD number? There have been a number of messages on the list, reporting problems, and my experience is the same. (Removing the existing OSD and creating a new one does work for me.) I'm working on
