[Moosefs-users] How can I improve the cached operation HIT

[liangzhenfang <lia...@ba...>]

Dear, mfser

 

I have installed the MFS.

But it can not cache the lookup operations .

Here is the mfsmount way and the cat .stats result

mfsmount -o mfsattrcacheto=60000 -o mfsentrycacheto=60000 -o
mfsentrycacheto=60000 -o mfswritecachesize=1024 /home/rrddata/ -H HOST

fuse_ops.statfs: 24

fuse_ops.access: 0

fuse_ops.lookup-cached: 75

fuse_ops.lookup: 12348564

fuse_ops.getattr-cached: 170

fuse_ops.getattr: 1578048

fuse_ops.setattr: 35

And How Can I improve the cache Hit.

Thank you very much in advance
