I just replicated a number of NAS shares from our main DSS to a temporary unit. I wanted to rebuild the SAN using version 6 and 64 bit.

When this was ready, I came to replicate back the data and realised that I made a serious mistake. The temp SAN had a single 2TB RAID 5 volume with I completely assigned to a NAS volume and now I realise that I do not have space for a snapshot volume!

You can call this inexperience and I agree and as a follow up I have a question and a suggestion.

Question

Is there a way around this issue that will allow me to replicate or backup the data without having a snapshot volume? I am 100% sure the data will not be amended or accessed during the replication.


Suggestion

I suggest that the volume manager should warn you if all space is going to be allocated and no space has been left for a snapshot volume, something like: “we note that you are allocating all space on this volume. If you go ahead, you will have no space for a snapshot volume and you will have problems in using the backup/replication features.”
