in a few days I've a setting to change in ceph.conf . to apply ceph.conf changes, which services need a restart ?

So having thought ceph probably uses those addresses to prioritize networks. I will set public to vm network range 10.1.0.0/16 . so another question: should pbs access the storage network using the public or cluster network?

we have this in our ceph.conf for few years. public_network = 10.11.12.0/24 cluster_network = 10.11.12.0/24 pve vm's run at 10.1.10.0/24 on a seprate pair of switches used in lacp bond . corosync.conf uses 2 other nics and switches for cluster communications. having read forum posts, pve...

Hello David with Ceph 15 the script has the following issue. ceph-deep-scrub-pg-ratio: line 104: $2: unbound variable # line 104: while read line; do set $line; echo $1 $($DATE -d "$2 $3" +%s); done | \ PS thank you for this script, we've been using it for a few years.

I want to manually edit corosync.conf to set ring network priorities . I am reading pve-docs/chapter-pvecm.html#pvecm_redundancy . my question is how do I set priority in the .conf ? # pvecm create CLUSTERNAME --link0 10.10.10.1,priority=15 --link1 10.20.20.1,priority=20 this is the totem...

ceph: 14.2.11-pve1

hello, I am looking to have our upgrade for ceph procedure updated. here is what we do now per 2017 notes: 1. apt update && apt full-upgrade 2. restart monitors, each after the other (wait for healthy...

so if there are files or directories at the mount point try this zfs set overlay=on tank replace 'tank' with your zpool name

does the zfs mount point have directories like dump , template etc? of so there is a zfs option to fix this, i'll look for it as i used it again a few weeks ago

off topic: we are looking at upgrading ceph switches. currently using Quanta LB6M 10Gbe. we have 40Gbe cards . we think Mellanox/Nvidia switches running cumulus linux is the way to go. however i know little on this subject. is cumulus a good fit in labs and clusters?

Hello Spirit. during the switchover to ifupdown2 I noticed a few warnings which you are probably already aware of. I assume these will not cause an issue. However there could be settings to avoid the warnings? # ifreload -a warning: bond0: attribute bond-min-links is set to '0' and...

so after looking at the network expertise the authors of ifupdown2 have at networking , i think we'll switch our pve cluster to use ifupdown2 .

auto bond0 iface bond0 inet static address 10.11.12.80/24 bond-mode active-backup bond-primary enp3s0f0 bond-slaves enp3s0f0 enp3s0f1 mtu 9000 ## OLD auto bond0 iface bond0 inet static address 10.11.12.80/24 slaves enp3s0f0...

thank you for the fast reply.

Hello, at our pbs system a warning had flashed about ifupdown2 or ifdown2 missing, so i installed it. after doing so my existing bond did not work so had to change /etc/network/interfaces to new bond directives. I have 5 pve nodes to get bond working on. My question: is ifupdown2...

Hello, for lxc to pbs or local vzdump we get frequent fails on busy systems. ### from email 606: 2020-11-01 19:57:16 INFO: Starting Backup of VM 606 (lxc) 606: 2020-11-01 19:57:16 INFO: status = running 606: 2020-11-01 19:57:16 INFO: CT Name: bc-sys6-buster 606: 2020-11-01 19:57:16...

that makes sense. so we will always have gc set up at the remotes.

I had assumed that a remote sync target did not need GC , since it should be a duplicate of the main pbs system. however that is not the case. the remote had 2TB+ more disk usage after a couple months of syncs. running gc fixed that. question: once pbs is stable, should gc still be...

naturally after marking this solved there were more fails like this last two days: - to local storage: INFO: starting new backup job: vzdump --all 1 --mode snapshot --mailnotification failure --compress zstd --quiet 1 --mailto fbcadmin --storage z-local-nvme INFO: skip external VMs: 108, 446...

just to complete this, a week or so after we had 1-2 fails per day lxc and kvm. that seems to be fixed by software updates for pbs and pve/kvm
