rbd

I have a situation where a snapshot reversion for a container (rbd backed) is failing with the error "unable to read tail (got 0 byte)" in the tasklog. doing a manual reversion using rbd snap works fine. proxmox-ve: 5.1-42 (running kernel: 4.15.3-1-pve) pve-manager: 5.1-46 (running version...

I have a weird problem with specific containers failing to snapshot; the end result is that scheduled vzdump tasks effectively fail and disallow any further vzdump jobs until manually killed. The thing is, if I MANUALLY take a snapshot using rbd snap create it works fine- its only via api that...

I've some troubles understanding backup/restore for a (CentOS) VM with Ceph storage, used as NFS server. Let say it is VM n. 100. I've added a hard drive to this VM (virtio1) and it is located on my ceph RDB storage. I do not want to backup this additionnal disk when I backup the VM as it is a...

[proxmox5] Newly created unprivileged lxc container fails to start. The failure is rather ugly, since there is basically no info on it: Aug 16 00:25:25 elton lxc-start[39248]: lxc-start: tools/lxc_start.c: main: 366 The container failed to start. Aug 16 00:25:25 elton lxc-start[39248]...

Hi all, I'm getting the error: "rbd error: rbd: couldn't connect to the cluster!" when i create a VM with rbd storage from GUI. I have installed the client keyring in /etc/pve/priv/ceph/my-ceph-storage.keyring. # rbd ls -p images #returns no error. The "images" is the pool I have created. #...

Hey, i found many threads with the same issue but all they have the same solution (missing keyring). I checked them but i din´t find my mistake maybe someone can give me a hint. storage.cfg: i´ve did: cp /etc/ceph/ceph.client.admin.keyring /etc/pve/priv/ceph/rbd.keyring file is now present...

Hi There, I'm woundering is there faster way todo backups from CEPH rbd pool? I have a ZFS as backup storage connected over NFS protocol with 10G network to Proxmox . ZFS has 12 Sata Drives in raidz When I do backup via proxmox tool then writing speed to ZFS is 10-15 MBs only But when I use rbd...

I am about to configure a NAS that’s suppose to supply the storage for 3 virtualization servers. And I need some advise regarding which base-system to chose. The NAS has good processors, sufficiently RAM, good disks and 10G connections between the servers… So I am mostly looking for general...

the gui only offers Full Clone for VMs on ceph volumes; ceph should be able to create linked clones fast and easy (as well as light snapshots, by the way). Full Clone creation doesn't seem to use ceph and thus extremely slow. PVE full clone was created in 43 minutes, while doing it in the...

Hello, i'm currently running a ceph cluster (Hammer), last weekend I implemented a cache tier (writeback mode) of SSDs for better performance. Everything seems fine except for disk resizing. I have a Windows VM with a raw RBD disk, i powered off the VM, resized the disk, verified that both ceph...

Hello. I have a production 3 node proxmox 4.1 cluster with an external RBD storage. The external RBD has 3 nodes, each one with a ceph monitor. The hostnames are ceph0{1,2,3}.mynetwork.com. The ceph cluster is healthy and everything works fine. My /etc/pve/storage.cfg is this: dir: local...

I try to map and mount a RBD pool (from a ceph cluster) into a LXC container without success …: /usr/bin/rbd map --pool rbd test --id test --keyring /etc/ceph/ceph.client.test.keyring rbd: sysfs write failed rbd: map failed: (30) Read-only file system The Ceph configuration file seems good...
