[ceph-users] Re: db_devices doesn't show up in exported osd service spec

With db_devices.size, db_devices shows up from "orch ls --export", but no DB device/lvm created for the OSD. Any clues? Thanks! Tony From: Jens Hyllegaard (Soft Design A/S) Sent: February 9, 2021 01:16 AM To: ceph-users@ceph.io Subject: [ceph-users] Re:

[ceph-users] How is DB handled when remove/replace and add OSD?

Hi, I'd like to know how DB device is expected to be handled by "orch osd rm". What I see is that, DB device on SSD is untouched when OSD on HDD is removed or replaced. "orch device zap" removes PV, VG and LV of the device. It doesn't touch the DB LV on SSD. To remove an OSD permanently, do I

[ceph-users] MultiSite Sync Problem and Shard Number Relation?

Hi, I am sort of newby to RGW multisite. I guess there is an important limitation about bucket index sharding if you run multisite. I would like to learn better or correct myself. And I also want to leave a bookmark here for future cephers if possible. I apologize if this is asked before

[ceph-users] Proper solution of slow_ops

Hi all, we are looking for a proper solution of slow_ops. When the disk failed, node is restated ... a lot of slow operations appear. Even if disk (OSD) or node is back again most of slow_ops are still there. On the internet we found only advice that we have to restart monitor. But this is not

[ceph-users] using secondary OSDs for reading

Hi, Quoting the page https://docs.ceph.com/en/latest/architecture/ location query over a chatty session. The CRUSH algorithm allows a client to compute where objects should be stored, and enables the client to contact the primary OSD to store or retrieve the objects. So clients contact the

[ceph-users] Re: db_devices doesn't show up in exported osd service spec

Hi Tony. I assume they used a size constraint instead of rotational. So if all your SSD's are 1TB or less , and all HDD's are more than that you could use: spec: objectstore: bluestore data_devices: rotational: true filter_logic: AND db_devices: size: ':1TB' It was usable in my

[ceph-users] Re: Can see objects with "rados ls" but cannot delete them with "rados rm"

Hi James, I don't have any experience past Nautilus, but I suspect the rados cli (and/or the client calls its using) still does not handle c strings well when listing objects with null characters in their keys. That would explain the repeated keys you're seeing. I've noticed a similar issue
