Can You Attach Amazon Ebs to Multiple Instances

How to attach one volume to multiple instances in EUCALYPTUS amazon aws cloud server

No, you can not attach one EBS Volume to multiple instances at the same time in Eucalyptus. You can only attach to one instance, then detach the volume and attach to another instance.

Is Multi-Attach of Volume (EBS) allowed only for Nitro-based instances on AWS?

t2.large nor g2.2xlarge are not nitro. The list of nitro instances is here and includes:

Virtualized: A1, C5, C5a, C5ad, C5d, C5n, C6g, C6gd, C6gn, D3, D3en, G4, I3en, Inf1, M5, M5a, M5ad, M5d, M5dn, M5n, M5zn, M6g, M6gd, p3dn.24xlarge, P4, R5, R5a, R5ad, R5b, R5d, R5dn, R5n, R6g, R6gd, T3, T3a, T4g, and z1d

Bare metal: a1.metal, c5.metal, c5d.metal, c5n.metal, c6g.metal, c6gd.metal, i3.metal, i3en.metal, m5.metal, m5d.metal, m5dn.metal, m5n.metal, m5zn.metal, m6g.metal, m6gd.metal, mac1.metal, r5.metal, r5b.metal, r5d.metal, r5dn.metal, r5n.metal, r6g.metal, r6gd.metal, u-6tb1.metal, u-9tb1.metal, u-12tb1.metal, u-18tb1.metal, u-24tb1.metal, and z1d.metal

Update

ALternatively, you can use EFS which works with not only all instance types, but also ECS containers and lambda functions.
