cache manager of nginx not clearing cache as expected

[omkar_jadhav_20]

Hi,

we are running nginx with version 1.10 on redhat 7.2 OS. We have set
max_seize limit for cache of particular application. But we have observed
that cache manager is clearing the space from cache but not at desired speed
. below are few details :
Filesystem                    Type      Size  Used Avail Use% Mounted on

/dev/mapper/vg_cache-lv_cache ext4      1.5T  1.4T  6.9M 100% /cache

------------------------------------
du -sh /cache/12007
243G    12007
--------------------
nginx conf corresponding line :
proxy_cache_path    /cache/12007 keys_zone=a12007:200m levels=1:2
max_size=200g inactive=10d;

----------------

In error.log we are getting continuous no space left on the device errors.
Please advise what needs to be done to avoid these types of scenario. We are
getting very frequent error of such types in out environment.
