I have an issue on HPE MSA 2050 SAS storage pool B read cache. It has a RAID5 disk group and an SSD read cache. The volume assigned to is a storage for hyper-v virtual machines. The cache has 182214 free, but only 7825 allocated pages.
Pool A has two disk RAID5 groups and a read cache with same size, it is used for also VMs and backups. The read cache is the same size and all pages are allocated.
I expect pool B read cache should also be allocated fully after a certain amount of time. Is it an error or feature?
