E2E CloudVolumes FAQ
What is a volume?
Section titled “What is a volume?”A volume is a disk that attaches to one of your nodes and gives it a file system it can read and write like a local drive. It is faster than reaching an Object Storage bucket over the network. See Block Storage.
What sizes can a volume be?
Section titled “What sizes can a volume be?”From 100 GB to 16 TB. You choose the size on a slider when you create the volume. See Create a volume.
How are IOPS decided?
Section titled “How are IOPS decided?”IOPS are bundled with the volume and set for you at 15 IOPS per GB of size, up to 240,000, fixed when you create the volume. See Create a volume.
Can I attach a volume to any node?
Section titled “Can I attach a volume to any node?”A volume attaches to a node that is Powered off or Running. See Attach a volume.
Does attaching a volume make it usable on the node?
Section titled “Does attaching a volume make it usable on the node?”No. Attaching exposes the volume as a new disk; you then format and mount it inside the node’s operating system. See Mount a volume on Linux or Mount a volume on Windows.
Does detaching a volume stop billing for it?
Section titled “Does detaching a volume stop billing for it?”No. You are billed for the volume until you delete it. See Detach a volume.
Can I delete a volume that is attached to a node?
Section titled “Can I delete a volume that is attached to a node?”No. Detach it first, then delete it. See Delete a volume.
Can I back up a volume?
Section titled “Can I back up a volume?”Yes. Take a snapshot of the volume, or schedule snapshots daily, weekly, or monthly, with a lifecycle that deletes old ones. See Create a volume snapshot and Schedule volume snapshots.
Can I encrypt a volume?
Section titled “Can I encrypt a volume?”Yes, by checking Enable Encryption when you create it. Encryption can be turned on only at creation. See Encrypt a volume.
Are snapshots of an encrypted volume encrypted too?
Section titled “Are snapshots of an encrypted volume encrypted too?”Yes. A snapshot of an encrypted volume is encrypted; a snapshot of an unencrypted volume is not. When you create a new volume from a snapshot, choose encryption again if you want it on the new volume. See Encrypt a volume.
Can I make a volume bigger?
Section titled “Can I make a volume bigger?”Yes, upgrade it while it is attached to a node. The size can only go up. If the volume has a snapshot, delete the snapshot or create a new volume from it first. See Upgrade a volume.
Can I move a volume to another project?
Section titled “Can I move a volume to another project?”Yes, to another project of the same account, if it is Available and has no tags. Its snapshots move with it, and a committed volume keeps its committed plan. The move itself is free. A volume attached to a node also moves when you move that node. See Move a volume to another project.
Can I move a volume’s data to another region?
Section titled “Can I move a volume’s data to another region?”Yes, by exporting it to an Object Storage bucket, then importing it in the other region. Export is available in Delhi. See Export a volume and Import a volume.
How is a volume different from Object Storage?
Section titled “How is a volume different from Object Storage?”A volume attaches directly to one node, like a local disk, and only that node can use it at a time. Object Storage holds files in a bucket reached over the network from anywhere. Use a volume for a node’s own fast storage; use Object Storage for files many machines reach. See Block Storage and E2E Object Storage.
