Odd VNXe 3100 Alerts
Setup:
Pool of free XenServer 5.6 servers running several VM over shared NFS storage (IE: no StorageLink)
VNXe: 1 TB NFS storage, nightly snapshots kept for 2 days and dedupe:
Current Allocation: 672.464 GB
Used: 495.634 GB
Thin: Enabled
Protection:
Size: 51.201 GB
Current Allocation: 51.200 GB
Used: 36 GB
Completely updated as of 7/21/2011.
I am receiving occasional alerts that look as such:
Storage associated with storage resource VM-DATA-01 is full
Then, as much as half a day later, I receive an alert saying:
Storage associated with storage resource VM-DATA-01 is operating normally
What I don't understand is, why am I receiving alerts that my storage is full, when, infact it is not? I get these alerts at all times of the day, so I don't believe it is associated with the 1am snapshots. I understand there is an alert set (somewhere) for 70% allocation, but I'm not there yet.
I've logged on and checked the health of everything every time I've seen the alert and the storage is always where it should be.
Is there some background process that would be using the extra space, temporarily?
Any tips, help or advice are greatly appreciated.

It would appear that is the case.
I have a snapshot schedule set for 1am with a 2 day retention. I should have 2 snapshots at all times and I currently only have one.
That would seem to be where the alerts are coming from. I will be increasing the share size soon, so the protection space will grow and hopefully the alerts will go away.
Thanks for your response.

Hi Chris,
The alert could be for your protection space. If your protection space exceeds 90%, you will get an alert its "filling". Do you see any snapshots being deleted automatically by the system due to running out of space? In a future release, we will be reporting more accurate alerts indicating either production or protection space is running low.
