[PVE-User] Remove a MON from a cluster...
Seems sufficiently clear, but i prefere to ask here. I need to remove a node from a PVE 4.4 cluster; the node was only a MON and OSDs node. I have to: 0) remove every single OSD, remove the host from the crushmap (done). 1) remove the node from the MONs (via web interface, or via: pveceph destroymon ) 2) edit by hand (seems there's no way in 4.4) /etc/pve/storage.cfg, adding/removing in 'monhost'; Q: some 'restart' are needed? 3) shut down the node, and apply: https://pve.proxmox.com/wiki/Proxmox_VE_4.x_Cluster#Remove_a_cluster_node Right? -- dott.

Re: [PVE-User] Proxmox Ceph workload issue....
Right now, the cluster itself are rebalancing for about 4 days... But since the third day, no performance impact in the environment, because I ran the command mentioned in the previously mail. Better slow rebalance then poor performance... --- Gilberto Nunes Ferreira (47) 3025-5907 (47) 99676-7530 - Whatsapp / Telegram Skype: gilberto.nunes36 Em seg, 10 de dez de 2018 às 07:33, Alwin Antreich escreveu: > Hello Gilberto, > > On Fri, Dec 07, 2018 at 03:34:42PM -0200, Gilberto Nunes wrote: > > Hi there > > > > I have a 6 nodes Ceph cluster make with Proxmox. > > In order to recude the workload rebalance, I activate some features, like > > this: > > > > ceph tell osd.* injectargs '--osd-max-backfills 1' > > ceph tell osd.* injectargs '--osd-max-recovery-threads 1' > > ceph tell osd.* injectargs '--osd-recovery-op-priority 1' > > ceph tell osd.* injectargs '--osd-client-op-priority 63' > > ceph tell osd.* injectargs '--osd-recovery-max-active 1' > > ceph tell osd.* injectargs '--osd-max-scrubs 1' > > ceph tell osd.* injectargs '--osd-scrub-max-interval 4838400' > > ceph tell osd.* injectargs '--osd-scrub-min-interval 2419200' > > ceph tell osd.* injectargs '--osd-deep-scrub-interval 2419200' > > ceph tell osd.* injectargs '--osd-scrub-interval-randomize-ratio 1.0' > > ceph tell osd.* injectargs '--osd-disk-thread-ioprio-class idle' > > ceph tell osd.* injectargs '--osd-disk-thread-ioprio-priority 0' > > ceph tell osd.* injectargs '--osd-scrub-chunk-max 1' > > ceph tell osd.* injectargs '--osd-scrub-chunk-min 1' > > ceph tell osd.* injectargs '--osd-deep-scrub-stride 1048576' > > ceph tell osd.* injectargs '--osd-scrub-load-threshold 5.0' > > ceph tell osd.* injectargs '--osd-scrub-sleep 0.1' > > ceph osd set nodeep-scrub > > > > Is there any troble if I leave this feature like above? > Well, you need to monitor your cluster and see if it helps or does any > harm.

Well, you need to monitor your cluster and see if it helps or does any harm. Also check with these settings, if your cluster will ever do scrubbing (or finish). -- Cheers, Alwin ___ pve-user mailing list pve-user@pve.proxmox.com https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
