- After booting up, the VM should now have an additional disk, typically named vd(SOME_LETTER) - below, we assume the disk is named vdb, but it may be vdc, vdd, etc if you already had a second, third, etc disk. You can check what disks are attached by running
lsblk
, which shows disks (e.g. vda, vdb) and partitions on the disks (vda1, vda2, etc for partitions 1 & 2 on vda)You should expect to see something like this, showing vdb with no partitions:
Code Block NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vda 252:0 0 20G 0 disk ├─vda1 252:1 0 19.9G 0 part / ├─vda14 252:14 0 4M 0 part └─vda15 252:15 0 106M 0 part /boot/efi vdb 252:16 0 128G 0 disk
Warning vda is your root disk - do not reformat this!
- If you don't see the new disk, check that it was successfully created by Morpheus (see creation section above). If it's there in Morpheus, but not visible in the VM, please contact support
Create a single partition (number 1, so vdb1) filling the disk, labelled "data-1" here, and format it. You may use parted and mkfs.ext4:
Please change the label name to match what you called the new disk in the Morpheus interface (this is not a requirement, but reduces confusion later)
Code Block sudo parted --script -- /dev/vdb mklabel gpt sudo parted --script --align optimal -- /dev/vdb mkpart primary ext4 0% 100% sudo mkfs.ext4 -L data-1 /dev/vdb1
Info You may partition the disk differently and use any other filesystem type. It is a good idea to use the same name for the volume to set the label of the new filesystem
- To have the disk automounted on start up, add an entry to your VM's /etc/fstab, adapting the label to the name you chose earlier:
Code Block echo "LABEL=data-1 /data1 ext4 defaults 0 0" | sudo tee -a /etc/fstab > /dev/null
Create the directory where you are mounting your filesystem. Make sure you use the same path as defined in fstab:
No Format sudo mkdir /data1
Mount the file system this first time around and check its ok. It should be automatically mounted on future reboots (test this now if it's important).
No Format sudo mount -av

Due to limitations in the underlying OpenStack infrastructure at ECMWF, a user cannot hot-plug more than 12-13 pci devices. This means that if a user wants more than 12-13 volumes, the the VM must be powered off, before more devices are added. |
