weka host memory
is set to 1.4 GB per compute-core, out of which 0.4 GB is used for the capacity requirement memory. If the default capacity requirement memory is not big enough to satisfy the total size of the filesystems, the least used metadata units will be paged to disk, as described in metadata limitations. If more RAM is desired for metadata, the memory allocation command must be performed in the install process. Having sufficient system memory is not enough.
