Hi, you could try to use ceph-volume lvm create --data DEV --db DEV.... and inspect the output to learn what is being done.

Re: Add OSD with primary on HDD, WAL and DB on SSD

by Eugen Block

Hi, if you shared your drivegroup config we might be able to help identify your issue. ;-) The last example in [1] shows the "wal_devices" filter for splitting wal and db.

Upgrade options and *request for comment

by Ed Kalk

Hello Ceph Users, We have a Mimic 13.2.10 cluster on Ubuntu 16.04.03 with 6 servers, 36 OSDs. Each OSD has a 2GB memory target via ceph.conf (30 spin disks with HDD type and 2 pools on them (2copy and 3copy pools), 6 SSDs in a flash pool (3copy)) Our intention is to upgrade the code level of CEPH only (Ubuntu remains the same on 16.04.03) and we have the choice of goto Nautilus or goto Octopus. **Does anyone have any warning based on upgrade attempts or advisement for Nautilus or Octopus? Our primary concern is simply code stability post upgrade. -- Thank you for your time, Edward H. Kalk IV Information Technology Dept. Server Specialist Datacenter Virtualization and Storage Systems Socket Telecom, LLC. 2703 Clark Lane Columbia, MO 65202 573-817-0000 or 800-socket3 X218

Add OSD host with not clean disks

by Tony Liu

Hi, I am trying to add a OSD host with not clean disks. I added the host. ceph orch host add storage-3 10.6.50.82 Host is added, but the disks on that host are not listed. I assume because they are not clean? I zapped all disks. ceph orch device zap storage-3 /dev/sdb ...... All disks are cleaned successfully. But I still don't see those disks listed. I tried to remove the host and add it back. ceph orch host rm storage-3 ceph orch host add storage-3 10.6.50.82 I still don't see those disks listed. Finally, I restarted mgd, then I see those disks listed. Is this expected or anything I'm missing? Thanks! Tony

Office Setup And Product Key

by sapohoj267＠qqmimpi.com

The office is a productivity suite, developed and maintained by one of the biggest companies, market leaders in technology, Microsoft Office. You must already have gotten your answer, Microsoft is not just another company that poses to be developing great software with just a team of 100 members but Microsoft is a big company that needs to keep its reputation and work always on par with the revenue they are getting. This means they need to hire the best people to get the job done and that’s how it works in Microsoft. There is no issue with Microsoft, but the only issue is that Microsoft has been the target for hackers for quite a while now, It is one of the easiest targets anyone can find when it comes to the customer base and data theft. The data Microsoft has stored on their cloud servers is enormous and is really important for most of the people.
