[sheepdog-users] clear object cache

[Maxim Terletskiy]

Hi!

I'm using this settings:

-g -c 
zookeeper:10.255.255.251:2181,10.255.255.252:2181,10.255.255.253:2181,timeout=30 
-w dir=/mnt/sheep_objcache,size=112G,directio -y 172.16.0.14 -D 
/var/lib/sheepdog

So I need to remove all data from metadata dir and objcache dir?
rm -rf /var/lib/sheep/*
rm -rf /mnt/sheep_objcache/*
