When I run Get-ClusterStorageSpacesDirect
command, I get the following warning:
WARNING: 2018/01 / 16-11: 11: 38.574 Node DB1: No disks found to be used for cache
WARNING: 2018/01 / 16-11: 11: 38.580 Node DB2: No disks found to be used for cache
CacheMetadataReserveBytes: 34359738
CacheModeHDD: ReadWrite
CacheModeSSD: WriteOnly
CachePageSizeKBytes: 16
CacheState: Enabled
State: Enabled
I noticed that when I copy files, I only get to a speed between 80 - 90 MB
Why do I get the error that no disk was found for the cache but CacheState and State are Enabled? Can this be the reason that the copy speed is only about 90 MB?
Thank you for your help
