Hi

I want to use a file as a counter when I create a file in dht xlator.

I mean, after creating a new file,  I want open a file in the same directory with a special name, read that, update the counter and write back. 

I think for this purpose I  should open in dht_create_cbk, read in dht_open_cbk and write in dht_readv_cbk.

I think I should use dht_open , dht_readv and dht_writev. Maybe I could create inputs for these function expect frame! is it correct to use the frame fro dht_create function?

Is this scenario correct or there is better way?

Have you tried the object count feature [1] ?

Regards,

Vijay
