Bump

Hi, We increased our PG count from 256 to 512 over the weekend to accommodate our growing CEPH cluster. The cluster has been in a healthy state and everything appears to be ok, except we have noticed 2 PG have been deep scrubbing for over 24 hours now. My questions: 1). Could this be Ceph...

We are currently running a 8 node cluster - 5 nodes are for computing, 3 nodes are for ceph. It's all in HA on a 10GB network - backups to NFS. Our data transfer speeds are around 40MB/s which is unacceptable for our needs. Curious if migration our backup solution to PBS improves this...

We're currently running a 8 node cluster - 3 nodes are dedicated to CEPH. All our QCOW2 files reside on the CEPH cluster and we do a vma.zst backup to an NFS share. Our network is all 10GBIT and we're seeing only 40MB/S backups which is becoming a big issue as our client base grows on this...

Figured it out. I need to review my switch config. Server is setup on a bonded interface running LACP. When I shutdown the port on one of two switches it resolves the OSD flapping and Ceph errors.

To add - in all scenarios I have OSD's going up and down (mainly on one specific node).

Hi All, I've done my best to read documentation and research the forums / web. I keep having these health errors pop up. I've tried a ton of different PG configurations including 128, 1024, 2000, etc. I can't seem to nail this setup - I've tried using calculators as well. I have 3 nodes, 8...

Nevermind - I used fdisk and purged both partitions on the drive.

One disk on one of our servers is labeled as a 'partition' (not sure why - clean install and all other nodes don't have the same issue) - as a result not able to add the disk as an OSD to our Ceph cluster. Anyone have this issue and know how to fix? TIA
