In the end, the issue was with SWAP. Seeing that this cluster was using PVE 6.4, I disabled SWAP on all nodes and the issue hasn't returned.
In PVE 7.x, SWAP is disabled by default so that could explain why I don't see this issue on the PVE 7.1 cluster.
I have recently migrated all VMs on a PVE cluster from a hdd pool to a ssd pool. Now that the hdd pool is empty (no VMs), ceph still reports 31% usage on the pool.
This ceph has been in use for a while now. Upgraded from ceph 12 to 14 to 15.
This is the second cluster where I noticed large...
I have a PVE cluster where a host is currently running with 80-82% of physical memory in use and SWAP at 99% in use.
VMs are configured with memory ballooning (min and max values). However, when the VM requests additional memory, it fails:
kernel: kworker/0:1: page allocation failure: order:0...
Yes. pre-assigning non-existing VMIDs to a pool is what I understood too.
So yes, pre-assigning non-existing VMIDs to a pool and giving the user Permissions.Modify or Pool.Allocate works.
However, if the user deletes the CT, it also deletes the associated permissions. This is a good workflow to...
No, there are no pre-assigned VMIDs on the pool.
Even after pre-assigning a VMID (e.g. /vms/200) with the proper vm.allocate, I still get a "Permission check failed (/pool/Dev, Permissions.Modify|Pool.Allocate) (403)" because the CT creation process also requires Pool.Allocate, not just...
If that is the case, then there is a bug with the LXC Container create. The user is part of a group which has permissions on the Pool with the built-in role PVEVMAdmin and on the storage with the built-in role PVEDatastoreUser. Both these built-in roles have VM.Allocate and...
A user is trying to create a CT using the PVE WebUI in a specific Pool (in this case, the pool is called "Dev"). The first error message he got was:
"Permission check failed (/pool/Dev, Permissions.Modify|Pool.Allocate) (403)"
I then added the "PVEPoolAdmin" role to the user on "/pool/Dev"...
My users can't seem to configure the "Start/Shutdown Order" of a VM. The users are part of a group with PVEVMAdmin role which allows them to set the "Start at Boot" option of a VM, but they can't access the "Startup delay", "Shutdown timeout" and "Start/Shutdown order".
Is this a bug or do I...
If a user is a member of Pool A and Pool B with the PVEPoolAdmin role on both pool A and B, is it possible for that user to move a VM from pool A to pool B ?
I noticed if the user removes the VM from the pool, he can't add it back to the pool or to any other pool... which makes sense. But how...
Thank you Ashley,
I marked the most full SSD OSD as out and that started the recovery process once again.
Should I be worried about the 2 scrub errors or wait until the whole recovery process is completed ?

I did have one, but not anymore. I was converting the whole cluster to have the block.db of each HDD on 1 SSD instead. So OSDs 0 to 5 have there block.db on an SSD and OSDs 6 to 11 are not (block.db on same device). My end goal is to take out the last 4 SSDs and place the block.db of each...
We had a crash of multiple servers in our CEPH cluster. Recovery ran all night, but this morning it stopped.
No more movement. Also, I have a warning that my pool is full (100%), but there is still full of room on the OSDs. Since I am quite new to Proxmox and CEPH, I would like to know how to...
