Hi Ceph Gurus, I have installed Ceph Luminous with Bluestore using ceph-ansible. However, when I did the install, I didn’t set the wal/db size. Then it ended up using the default values, which is quite small: 1G db and 576MB wal. Note that each OSD node has 12 OSDs and each OSD has a 1.8T spinning disk for data. All 12 OSDs share one NVMe M2 SSD for wal/db. Now the ceph is in use, and I want to increase the size of db/wal after doing some research: I want to use 20G db and 1G wal. (Are they reasonable numbers?) I can delete one OSD and then re-create it with ceph-ansible but that is troublesome. I wonder if there is a (simple) way to increase the size of both db and wal when an OSD is running?
Thanks in advance, Shunde. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
