Linode Block Storage (Fremont beta)

What is the Linode Block Storage service?

The Linode Block Storage service allows you to create and attach additional storage volumes to your Linode instances. These storage volumes persist independently of Linode instances, but can easily be attached from one Linode to another without the need to reboot. Volumes attached to Linodes appear as block devices and can be formatted and mounted just like any other block device.

Block Storage Volumes are highly available with 3x replication. They're fast - built on great engineering, NVMe/HDD hardware, and a fast network. They're affordable - $0.10 per GB (free during the beta) and no usage fees. They're cloud: elastic, scalable, expandable, resizable, etc. You can hot-plug them into and out of running Linodes. Oh, and you can boot off of them, too.

What can I do?
  • Create Volumes
  • Remove Volumes
  • Resize Volumes
  • Duplicate Volumes
  • Attach a Volume to a Linode
  • Detach a Volume from a Linode
  • Add Volumes to your Linode Configuration Profile block device assignments (changes take effect next boot)
Snapshotting and Volume backups are not implemented - but may be in the future.

Can I attach a Volume to multiple Linodes?
Nope. A Volume can only be attached to one Linode at a time.

How big of a Volume can I create?
Between 1 GB and 1024 GB for now. After the beta, the max volume size may be larger.

How many Volumes can I attach to a Linode at the same time?
Up to 8.

Can I mount Volumes across datacenters?
No. Volumes and instances must be in the same region.

Is there API support?
Yes - https://developers.linode.com/v4/refere ... de#volumes

How does the beta work?
  • The beta is free through 2017. UPDATE: Free through January 31, 2018. February, 2018 the meter starts running.
  • Volumes can only be created in our Fremont, CA datacenter. You will need to have at least one Linode there.
  • This is a beta. Be smart with your data.
How can I get in on this?
The Block Storage beta is public. You can click Manage Volumes off the Linode index page. We'd very much appreciate any testing and feedback. You're welcome to reply to this thread or create a new one in the beta category, or email us, or open a ticket - whatever works.

Thanks,
-Chris

Yay!

Just to confirm, I just created several and the instructions said they're going to be attached momentarily. However, it's been a good 10-15 minutes, and none of them have shown up yet. Is that normal?

Hi,
I know a couple months ago when it was said Fremont would have the beta, it was also said that the other data centers would probably go much quicker with implementing and having block storage available. Is there any estimated timeline on that, or even a best guess? I've got my Linode in Dallas that I'd like to use block storage with, but I don't want to migrate to get it. I'm just interested in a estimate or guess as to the wait time for the implementation of block storage in Dallas.

Also, how stable is block storage now? Is data loss a likely possibility while it's in beta? Will any formats or anything of that nature change significantly enough to require that you set up your block storage again once it's already been used? Knowing Linode, the transition in such cases is likely to be seamless, but I thought I'd check to be sure.

Blake

Thanks for your questions, Blake...

> I'm just interested in a estimate or guess as to the wait time for the implementation of block storage in Dallas.

This is part of the problem with guessing - it can set an incorrect expectation.

For us, the most important thing was to gain the experience and confidence in our engineering, and to come up with a configuration that met our objectives. We feel pretty confident in the Fremont cluster's config, but that's the entire point of doing a beta: to get that validation. Unless we learn something new during this beta, this will be the config we roll out to the remaining DCs -- which will likely begin a few weeks from now. Dallas is at the very top of that list.

> Also, how stable is block storage now? Is data loss a likely possibility while it's in beta?

Data loss is a possibility in life in general, but so far the Block Storage service has been solid / stable.

> Will any formats or anything of that nature change significantly enough to require that you set up your block storage again once it's already been used? Knowing Linode, the transition in such cases is likely to be seamless, but I thought I'd check to be sure.

Doubtful, but it's a possibility.

Does this storage act like an external drive? Could we use it to run rsync commands to backup files?

Yes and yes.

Hello, i am using the block storage since it was released. But the problem i faced recently is my 40GB block storage is not attaching to any linodes any more. It was okay in the past. I already opened a support ticket. They said they would notify me asap as i have some files in there. It shows this error message "DiskID volume664 is not a valid DiskID".
Storage service is great :D <3 But please solve this issue.
Thank you.

^^ That's alarming. Curious to hear the cause.

I'm seeing a weird issue with the same block device mounted on 2 Linodes, with one left in a weird ghost mode. Filed a ticket with support (https://manager.linode.com/support/ticket/8988939), but if you want, I can paste its content here @caker.

We are currently having Linode set up at Singapore, SG. We are really in need of the block storage option to expand the storage. Please let us know a rough estimate on when the feature will be expanded to Singapore, SG?

Is the replication on volumes synchronous or asynchronous? And do individual writes obey the sync settings sent by the OS? Is the data cached in NVMe and de-staged later? Trying to get a feel for the implications of running a DB on the remote storage as opposed to local.

Storage has always been one of Linode's weaknesses. This will be game changer. Very exciting!

Since it's got some spinning disk would be awesome if it could be priced "cheaper than the competitors"...just sayin' :)
Cheers!

It would be great if someone could answer this! It is very difficult for people like me to get a response from the linode team. Gives me no other option other than moving to some other hosting providers.
