Thank you so much. You are a life saver. So this mean I do not need to route the network between the two switches. The nodes with VMs will just be communicating on their own switch. Correct? I plan to upgrade to a 10GB network soon. Does the theory of having 2 switches to ease traffic...

Thank you much. Where can I get a command line reference guide for CEPH?

Thank you very much. Do you mind sharing your hardware config? How about network diagram? I am still confused about the part where it was suggested to run OSD nodes on separate network but also let the nodes with VMs connected to it? Is there a command line reference guide for pveceph or CEPH...

Thank you very much. How about backing up to a local storage on the node itself? I should be able to that right? The backup storage option is empty, it does not offer even local storage. "Ceph cluster crashes". That sounds scary and has been on my mind since the initial installation stage. I...

Hello, Can anyone show me how to back up the VMs on a CEPH? I can take snap shots, but when using the Backup option, the "storage" option is empty. Thanks in advance for your help.

Thank you very much. Is there an official documentation on how to setup HA for the VMs on CEPH? I read somewhere stating that CEPH is itself HA. But that's the confusing part. Isn't CEPH's purpose is storage only? Which mean I still need to configure HA using some references like this...

I am confused. There are two documentation ProxMox put out for installing CEPH: 1) http://pve.proxmox.com/wiki/Ceph_Server OR 2) http://pve.proxmox.com/wiki/Storage:_Ceph and then there is this one: 3) http://ceph.com/docs/master/install/ Which is the best one to use?

Hello, Apologize in advance for all the newbie questions. 1) When I try to back up a VM Nodes -> Backup -> Backup now, the storage option is empty. It doesn't allow me to select the pool/storage I am using for the VMs. Taking snap shots of the VMs works fine. Any advise? 2) How do I...

Thank you very much! This is very helpful.

Thank you very much. That is very helpful. So to increase the PGs, it can only be done via the command line and not the GUI? Also, are these two commands pretty much the same? ceph osd pool set poolname pg_num 512 ceph osd pool set poolname pgp_num 512

Hello, Could someone spare a moment to help with these questions? 1) I thought the PG and replicas number can be change at any time (per previous threads). But I don't see a way how to do that after the creation of a pool and storage. As I can see now, the only way is to delete it and create a...

Sorry in advance for the newbie question. I set up 3 CEPH Nodes. I would like the VMs on each node to communicate with each other via the hosts main network interface while using a different subnet. What is the proper way to do this? Thanks in advance for your help.

Hello, Can anyone confirm for sure that the next version of CEPH no longer need dedicated journal disks? I am setting up from scratch. If it is true the CEPH will not need dedicated journal disk, then I may as well set up right now for it to put the journal on the OSDs. I just don't know how...

Thank you very much. That makes a whole lot of sense.

Thank you very much for your help. Back to my original comment about Proxmox/Ceph's showing available storage space. Since it is showing TOTAL available and not ACTUAL, I just have to be careful and not storing more than I should? For an example, total available it is showing 30TB. Since I...

Thank you. I was referring to Image #2, which show available space. The size is showing total size of the entire pool. In your image example, the replicas are divided by 3, it should show 17.53TB as the available space (52.59 / 3)? Thank you much but I am confused and it doesn't make sense...

Hi, The file size is only 120MB to 250MB. I have not tried to upload it through FTP program like FileZilla. Right now, I can still download the templates to local directory, but uploading ISO of any size will give that 500 error. I re-installed everything from scratch. Before adding CEPH...

I just did a fresh install of the nodes from scratch. Setup CEPH and activated OSDs. Straight out of the box, I cannot upload the ISO to the local drive (boot) of any node. Can anybody shed a light on this problem? "Error: 500: can't activate storage 'local' on node 'CEPH1' " Perhaps this is...

It won't work. "Error: 500: can't activate storage 'local' on node 'CEPH1' "

Thank you. 1) So I just need to keep in mind of the maximum my users can store? For example, if I do 3 replicas on a 30TB, then I just need to make sure used space can be no more than 9.5TB or 10TB? 2) Another question. What is the main advantage to having 3 replicas versus 2 replicas...
