Can cfncluster mount the existing ebs volumes? about aws-parallelcluster HOT 6 CLOSED

You can choose to use an EBS snapshot as source for a volume. If you have
an existing volume, make a snapshot and then provide it in the config.

Also happy to investigate an option to provide existing EBS volume Id to
mount.

Can I automatically mount the existing ebs volumes to a cluster if I have

in the configuration file before create/start a cluster?

Thanks,

Thanks for your comments!

Does using an EBS snapshot work for your current scenario?

I tried to use a snapshot but looks like it did not work. The below is my EBS settings,

ebs_snapshot_id = snap-507e03de
volume_type = gp2
volume_size = 50

Please let me know if it is not correct. Thanks!

Within the cluster section, you need to make sure you are explicitly calling out an ebs settings section. So for example, you should have something like this:

[cluster default]
key_name = my key
ebs_settings = mysnapshot
vpc_settings = public

[vpc public]
vpc_id = vpc-a1b2c3d4
master_subnet_id = subnet-a1b2c3d4

[ebs mysnapshot]
ebs_snapshot_id = snap-a1b1c1d4
volume_type = gp2

You do not need any volume_size as that will come from the EBS snapshot.

It works now, thanks a lot!
