Space Utilization alert messages

[taylorb]

I've got a very full P4500 cluster that keeps giving me odd error message patterns.  At least once per day, I'll get an email saying it is 97 or 95% full and then 1/2 hour another saying it is back to 90% full, which is what the usage summary tab shows. 

I am using Network RAID-5 on a few volumes, is the excess capacity spike the snapshots that the NR5 uses and then it level off after copying?

I'de bet it is, but if you want to know for sure you probably have to contact support.

From what I remember, and I could be wrong here, but network RAID 5 requires a snapshot, and every day there is a scheduled task that takes a new one and rolls up the old one. There was a bug in the 8.5 SANiq that calculated the used space incorrectly. I'm not sure what version you are on but that could be the issue.
