Can you open a ticket with exact version of your ceph cluster? http://tracker.ceph.com Thanks, On Sun, Dec 10, 2017 at 10:34 PM, Martin Preuss wrote: > Hi, > > I'm new to Ceph. I started a ceph cluster from scratch on DEbian 9, > consisting of 3 hosts, each host has 3-4

IIRC there was a bug related to bluestore compression fixed between 12.2.1 and 12.2.2 On Sun, Dec 10, 2017 at 5:04 PM, Martin Preuss wrote: > Hi, > > > Am 10.12.2017 um 22:06 schrieb Peter Woodman: >> Are you using bluestore compression? > [...] > > As a matter of fact, I

Hi (again), meanwhile I tried "ceph-bluestore-tool fsck --path /var/lib/ceph/osd/ceph-0" but that resulted in a segfault (please see attached console log). Regards Martin Am 10.12.2017 um 14:34 schrieb Martin Preuss: > Hi, > > I'm new to Ceph. I started a ceph cluster from scratch on
