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 /sda1/cache0 30720 50 256 min-size=16384 max-size=18874368
cache_dir aufs /sdb1/cache0 30720 50 256 min-size=16384 max-size=18874368
cachemgr:
Internal Data Structures:
2412947 StoreEntries
27350 StoreEntries with MemObjects
26900 Hot Object Cache Items
2410991 on-disk objects

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