replying to my own post, it does seem that cachemgr counts number of
objects from all available cache_dirs. in my case, the number of objects
of size 0-16kb was so huge that shifting them to a small 4G coss dir
caused to drop total number of cached objects massively. I've no added
12G more to the coss dir and the number of objects is now picking up well.
thanks any ways.
Thank you for this feedback. It is very useful to know.

Hi all.
I've recently added a coss storage to our cache and is performing
great. But I see that the cachemgr is showing the decrease in
storeEntries count and also the mean object size has increased from
~15k to ~25k. before coss was introduced, we had 64G of cache_dir
split into 2 scsi disks and ~4m objects in the storage. now we
introduced 4G coss dir with max object size of 16k on a separate sata
disk. and after 4 days of operation, coss storage is 82% full and the
cachemgr reports that we only have ~2.4m objects in the storage. we're
using squid 2.7S3.
squid.conf:
cache_dir coss /coss/cossfile 4096 block-size=512
max-stripe-waste=16384 max-size=16384

cache_dir aufs /sdb1/cache0 30720 50 256 min-size=16384 max-size=18874368

does cachemgr count the store entries in coss stores as well??
Thanks
