Hi,
I have nginx serve as image cached, here is the main config :
proxy_cache_path /etc/nginx/cache-media levels=1:2 keys_zone=media:1000m
inactive=2y max_size=100g;
proxy_temp_path /etc/nginx/cache-media/tmp;
/dev/sdc1 is an intel SSD with ext4 mounted (-o noatime, nodiratime).
It looks like that the nginx do not evict the old cached files :
Disk usage on /dev/sdc1 :
df -h /dev/sdc1
Filesystem Size Used Avail Use% Mounted on
/dev/sdc1 110G 102G 7.5G 94% /etc/nginx/cache-media
the max_size=100g but the real size has been raise up to 102GB.
Sometime it full up to 100% of the sdc1 disk and get errror : 2015/04/27
12:03:55 [crit] 7708#0: *18862126 pwrite()
“/etc/nginx/cache-media/tmp/0004826203” failed (28: No space left on
device)
while reading upstream,
and I need to manually remove by find && rm -rf
My nginx -V :
