rbd

Just noticed this on one of my clusters; disk resize is failing with the following error message: Resizing image: 100% complete...done. mount.nfs: Failed to resolve server rbd: Name or service not known Failed to update the container's filesystem: command 'unshare -m -- sh -c 'mount...

Hi all, So I have two external Ceph clusters - one is using IPv4 and the other is using IPv6. When I'm using IPv4 cluster, the dashborad shows status and content of RBD and I have no problem creating new images for VMs. But when I try to configure storage information about IPv6 cluster, I get...

Hello! Can you please share some information why storage type rbd is only availabel for Disk-Image and Container? I would prefer to dump a backup to another rbd. THX

Hi, I have created a pool + image using this commands: rbd create --size 500G backup/gbs Then I modified the features: rbd feature disable backup/gbs exclusive-lock object-map fast-diff deep-flatten Latest step was to create a client to get access to the cluster: ceph auth get-or-create...

Hi Community, to create a rbd image of 1T with an object size of 16K is easy. I did it like this: rbd create -s 1T --object-size 16K --image-feature layering --image-feature exclusive-lock --image-feature object-map --image-feature fast-diff --image-feature deep-flatten -p Poolname vm-222-disk-4...

I have this intermittent problem with storage returning 0 values for a specific rbd pool. Its only happening on one cluster, and there doesnt seem to be a corrolation to which node context is being called...

Recently I had to re-install Proxmox on my SSD's since replication is not supported in LVM, had to make "sort of a backup" of some files from a container that are around 250GB. To achieve that I mounted a disk using ceph storage, transferred the files to the storage, unmounted the disk...

I have a new problem (well, it could be old and I just noticed it.) I have a number of containers that show any number of snapshots but when I look at the disk those snapshots dont exist. Example: pvesh get /nodes/sky12/lxc/16980/snapshot 200 OK [ { "description" : "Automatic snapshot...

I use Ceph / rbd as storage and operate the container environment, but backup occasionally fails. Is there someone in a similar situation? [304948.926528] EXT4-fs error (device rbd5): ext4_lookup:1575: inode #2621882: comm tar: deleted inode referenced: 2643543 [304948.927428]...

Found issue when cluster have several RBD(external) storage's with same pool name. Creating, deleting rbd image works without any issue, but "move disk" or when qemu have same disk names on different storage's cause an error - proxmox doesn't understand what storage currently in use. Moving...

Hi Proxmox, I am unable to start VM on Ceph RBD external after recent update. From inside Proxmox, I could perform `rbd ls`. What just went wrong? kvm: -drive...

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...
