According to that screenshot, that VPOOL1 pool is full already, 0 GB available.. check & fix that, it can cause many issues. And if you are using compression for LUNs, it may fail due the lack of free space on the pool.
Hello Admins,  This issue is from a VNX5400 which shows a thin lun user capacity and consumed capacity different.   The VNX specs are:  Block version: 05.33.000.5.081 File Version: 8.1.3-79  [IMAGE] Why do we have this much difference in total capacity and consumed capacity. This way we will run out of pool space quickly for larger LUNs.  Please advise.
