Snapshot size limit exceeded.
In disk group 3 (DG3) of PowerVault MD1220, volume VD33-XEN-DATA33 says the limit has been exceeded. I've moved the VMs from this volume to others in case I need to make any changes. I don't know what to do. This snapshot configuration is old. Other disk groups do not take snapshots.
One question, if I have RAID 5 why do I need snapshots?

Hi,
Thanks for your question.
Page 99, https://dl.dell.com/topicspdf/pwv-md34xx38xx-ag_en-us.pdf Snapshots are a point in time copy of data, so if you had something deleted you could roll back, which a raid 5 doesn’t protect against. But if you don’t need them you should be able to delete them.
Let us know if you have any additional questions.
