    How to manipulate the extra raw storage of a VM

    Did it!!!!!!!!!!!!!!!!!!!!!!!!! My way, but did it!!!!! Here follows an example as I would like it to be read from me by someone else's answer Node 1: Make a backup of the VM with the extra storage and locate it at /var/lib/vz/dump/...vzdump-qemu-103-2022_03_16-01_06_43.vma.zst Copy/move this...

    How to manipulate the extra raw storage of a VM

    ... probably, but it seems weird since the snapshot is self is part of the storage and depends on that. So when you move only the snapshot to another place, that other place doesn t include the origin of the snapshot just the snapshot. Its like you move only the links to another place and the...

    How to manipulate the extra raw storage of a VM

    Depends. Are you talking what happens in GUI or inside the .conf file? Because in GUI nothing happens and nothing ever will :) In .conf it automatically adds the line unused0: local-zfs:vm-102-disk-2. Basically what I ve answered to @Dunuin <<<Only one line inside the VM s .conf file...

    How to manipulate the extra raw storage of a VM

    You are not late at all. On the contrary you kept me from slicing that damn machine with a katana!!! :) So once more, if you detach the disk there is not disk afterwards to edit or double click .It vanished and that s it (from gui perspective). You can check it yourself. the extra line in...

    How to manipulate the extra raw storage of a VM

    I don t know where this info comes from, but after someone detaches the storage there is nothing (without even running qm rescan) anymore to re attach there. Only one line inside the VM s .conf file corresponding to that extra storage which is unused0: local-zfs:vm-102-disk-2. If I just delete...

    How to manipulate the extra raw storage of a VM

    nope.... ti gives only the option to detach it. Probably afterwards cli is the only solution like the way I did it (described above) ...so there isnt a way? ...didn t know that info about octets. Nice Extremely thankful for the above info. Since I m at work right now, I ll check both ways and...

    How to manipulate the extra raw storage of a VM

    ...this is where a virtual @Dunuin would intervene to clear things out by saying (copy -pasting his answer from another post) <<<I guess you should read a bit how ZFS works, especially the difference between a "dataset" and a "zvol". Your VMs virtual disks are zvols, so they are not part of a...

    How to manipulate the extra raw storage of a VM

    Hi I am struggling finding a way (at least the most proper / valid one) on how to move the raw disk space of a VM (after detaching it) to another VM (on the same or different server) My installation is based on zfs. I Installed two Win10 VMs and I gave the first one (VM id 102) a second...

    Passing through Hdds with qm set command

    I hope didn t know that and therefore hoping this should be the solution or at least a new trial and error try. Here are the part numbers of all the equipment needed. I omitted to type the part number of the steel 8 bay cage but ok it has no electronic or electrical parts, just a still cage...

    Passing through Hdds with qm set command

    fair enough. That leaves us with the extra layer then, which even small one it exists though. exactly searched every menu couldnt find a relevant field. Also Dell's forum someone could have said something but others having the same problem, let it unsolved, changed cabling and were ok (already...

    Passing through Hdds with qm set command

    .... maybe because they can be recognized? Not confident just asking. Maybe a known defective drive in a pool with this way could give the answer. If scrub could find results and had already happened on the main system where that same drive were passed physical, then we could have a more...

    Passing through Hdds with qm set command

    Thank you for your thorough answer. I am aware of that and don t want to risk and find out in a production system the implications an action like that might have. I am sticking with the other two ways -find a way to bypass the error message with the second hba adapter controlling the second...

    Passing through Hdds with qm set command

    But I am doing this.I have 2 hba adapters inside the server.The embedded h330 mini mono (flashed to IT) who connects to the first 8 drives and a pci-e one (hba330) connected to the other 8 disks. It doesnt play along due to that damn error message I should have started with... this VM will be...

    Passing through Hdds with qm set command

    I know about that but in my case it can t be done since the R730 even though has all the connections for a second 8-bay backplane (mine is the 8 bay model) it refuses to play along and gives (probably) fake error messages about the cable or the card having being disconnecting. If I press the...

    Passing through Hdds with qm set command

    Hi I ve seen a different way to pass disks to a VM when an hba card is out of a question for some reason. You find the id (disk-by-id) of the drive (which doesn t change like sda sdb...etc) and you pass it through to the VM with the command qm set id_of _the_vm -iscsi(0,1,2,3....n)...

    add node that conatins vm's to cluster

    Well known path didn t know though that it is required only one step to rename the id of a VM. Didn t have to do it up until now. why would i want to change the storage name like for instance scsi0 to scsi1 or something? This name is within the Vm-id. I can t see the reason for this to change...

    add node that conatins vm's to cluster

    What about if I -backup the VM first and delete it afterwards by also checking Purge from job configurations and Destroy unreferenced disks owned by guest -join the node to cluster and restore the VM afterwards? What if the backed up VM on node B has the same id number as another VM on node A...

    Is this a right way to shrink a .raw secondary disk attached to a VM?

    So many info shared here. None agrees or disagrees with the procedure ..... it reminds me of the forum 2 years back when there were posts only to exist.
