Hi. I am currently facing the following problem. I have a couple of VM's with 1 Core CPU and 1GB RAM allocated to them. After a software upgrade on it the 1GB RAM is not sufficient maxing out the RAM. This causes high CPU usage from the kswap0 process. The CPU utilization then spikes to...

Average OSD size is between 60% and 70% - with the odd one or two that grows above 80%.

Hi I had an issue today where one of my disks was busy failing with high latency of over 1000ms. I immediately stopped the disk and out it. However, after that a handful VM's was non responding. I saw under Ceph Health that there were 2 inactive pg's and only after a hour or so they...

I got to a big scare when that happened I never used containers on a ceph pool again, I instead used a NFS share for my containers and Ceph for my VM’s. I havent run into an issue again. I also stopped using containers as well because they can bring a Node down totally, I have to reboot a Node...

I have added a new node and created additional OSD's. Migrated all the VM's and rebooted the problematic node, the reboot fixed my issue. Thank you.

I am not in a position to reboot the node yet because it is in production and no space on the other nodes. I am planning to add another node in the following week. I was just wondering if there is not a service I can reboot that might resolve this as my current pool utilization is at 90%. I...

Hi I am trying to add additional OSD's to my cluster, but it is not being created. I do not get any errors, after the createosd command it runs through everything and stops/freeze at "The operation has completed successfully" See below. After that "Ceph OSD sdc - Create" just runs under...

Hi all. Is there a way where I can get a list of disk drives of VM's on a specific OSD? Currently I am running the following. ceph osd map SSD vm-100-disk-0 But that is when I already know the disk name. I want to find out which VM is hogging DIsk IO on the OSD that is currently slugish.

Hi I am configuring Ceph on a 3 Node PVE Cluster with mixed SSD and HDD. I am currently creating a ruleset with specific class - following https://pve.proxmox.com/pve-docs/chapter-pveceph.html I need to specify a failure-domain but I am not sure what to set it to. Will someone be able to...

Hi Yes, it happened to two VM's whos hard disk I resized. Sorry I mixed the screenshots up. Here is 2043. I am certain that all my nodes can access the ceph cluster as I have a running VM that is using the same RBD pool on Node4.

Noted, thank you. Here is 'qm config 2043' - I removed the description and name. bootdisk: sata0 cores: 2 cpu: qemu64 description: memory: 4096 name: net0: e1000=96:5A:D3:97:23:85,bridge=vmbr0 ostype: l26 smbios1: uuid=7ee88c89-97a5-44de-a826-3a0cbb684eda sockets: 1 unused0...

I changed the storage to KRBD in the morning and later that afternoon I made the resize. This is what syslog says Dec 5 15:55:28 node6 pvedaemon[3924629]: <root@pam> update VM 2043: resize --disk sata0 --size +100G Dec 5 15:55:28 node6 kernel: [8669263.134425] rbd1: detected capacity change...

Hi I have a 7 Node Cluster with CEPH - RBD. I have a lot of existing VM's running on the cluster and decided to try out containers. I noticed that KRBD needs to be enabled to do that. I went and tick the KRBD box and added "Container" to content together with "Disk Image" in RBD. I then...

Hi I purchased 10GB TN9510 cards to use for my Ceph network, but cannot seem to get them working. dmesg shows the following. root@proxmox1:~# dmesg | grep tn40xx [ 6.444671] tn40xx: Tehuti Network Driver, 0.3.6.15 [ 6.444740] tn40xx: Supported phys : QT2025 TLK10232 AQR105 MUSTANG...
