Actually the size of a pool with 2k size on a 2k server (generally the smallest pool) can not be set to 0.
The minimum size of the pool is 256 pages.
On a 2k server when you add 8k pool, still the 2k pool has to be 512kB size (on a 4k server - 1MB, etc.)
In your case you can set the size of the 8k pool in the cache to 59,5MB, that is 60928kB.
You could try to set the 2k pool manually in CFG file, still you will receive error:
Invalid pool size of 0k (0 buffers) encountered for the 2k pool in cache my_cache. Buf
fer pools must have a minimum total size of 512k or 25 buffers, whichever is greater.
