Hi to all. I have one intel modular server, with 2 server inside and 8 disk. I need to expand the disk space, so I've bought other 8 SAS disk. Putting inside the IMS chassis and create storage pool is not a problem. Now the question is: can I add the virtual drive (using the Shared LUN...

This command will remove ALL the proxmox kernel, included the one you are running on.

You can do both. Snapshot is for "fast recovery" but snapshot doesn't care about services running inside the VM. Let think about an SQL server running a big transaction and , in the middle of, a VM snapshot. It's possibile that you will find your sql server in an broken status. With SQL dump ...

This is one way to do it. Remember that you have to check if the VM snapshot work after backup. IMHO, a better way, is to save the database dump/files/system status on a folder (with ntbackup or other tools) and then transfer it to tape. You can save VM snapshot too, but you cannot be sure of...

Re: Backupproblem with Snapshot, VM crashes sporadically after starting backup proces Is your proxmox installation a baremetal one, or did you installed debian and after that the proxmox kernel with pve packages?

You can install an iScsi server on proxmox host and connect the tape drive with iscsi client on the VM. Better if the VM is a system like bacula that directly handle the backup for each files on VM.

There is no proxmox log like var/messages or so?

post the output of dpkg -l | grep pve mount and proxmox related log

This is not my scenario. My crash happened with only a single backup on NFS share (QNAP). The VM simply power off (not a clean one, like a power loss). For now, I workaround that problem by removing that VM from nightly snapshot and running other backup methods.

It seems a problem with file system mount point. (search for "Transport endpoint is not connected" in google and you will see a lot of related problems) I'm not sure what to do. A server restart can be a solution, which will remount all the pve filesystem (I hope). But to be sure, I will wait...

As system say: E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). Be sure to have a valid backup before.

I had the same problem on my proxmox 2.3 version. VM suddenly hang during snapshot.

post your sources.list what an "apt-get install proxmox-ve-YOUR VERSION NUMBER" do?

I had no time for make tests, but it seems a QNAP NFS problem. I have the similiar behaviour with a ts-859u-rp+ Can you place a test setting up an nfs share (on a real server) and try a backup?

Arte you using NFS?

Running mysql with FLUSH TABLES WITH READ LOCK before the backup will resolve the problem.

Ok, let's try with another way: Start with a linux live cd. Mount c: in rw Edit file boot.ini according to this:http://support.microsoft.com/kb/239780 Now save and reboot. You will find the option for safe boot. If u cannot use arrow keys, put the safe mode as first in boot.ini file so will...
