Snapshots of multiple EBS volumes in a Linux VG

This may not be the forum for this – if so apologies but it has come up at work an no one is to sure if the risk we perceive is real.

Scenario :

  • You have a filesystem requiring high throughput / you wan redundancy of failure of a volume through RAID

  • Rather than one EBS volume you use Linux Volume Groups and Logical Volumes to create  a stripe set of EBS volumes

When you do snapshots  – how do you ensure the VG integrity without downtime to unmount the filesystems and snap each of the EBS volumes in the same state?

I hope I’ve presented the question clearly.
