At present, we have 5 same nodes made into one cluster. we created 4 volums which using Nraid1. Cluster storage space has used up.
Because the reason of storage space, we want to change the 4 volumes Nriad level from Nraid 1 to Nraid 5 directly. Can we do it directly like as Smart array Raid migration?
Solved! Go to Solution.

SolutionI am guessing you really mean NR-10?
I am thinking that your best option would be to migrate data off if you could.
If you cannot then I wuold make the volumes all thin provisioned. This should free up lots of space.
If that is not possible then for performance reasons I would only convert the volumes that are low use (read only) to NR-5.
Dont forget you must make the NR-5 volumes thin provisoned.
I also remember there being some kind of bug where if you attempted to convert the volume to NR-5 and did not have sufficent space it woudl shut down everything.
So number 1 make all volumes thin provisioned.
Wait to see how much space it frees up.
Then make sure you only convert volues that dont have high I/O to NR-5
Make sense?
