Hi,

I install mongodb on my Debian server on OVH, it was successful.
But I have an issue when i start mongo, but mongo client works :

MongoDB shell version: 3.0.1
connecting to: test
Server has startup warnings:
2015-04-09T08:52:05.807+0200 I STORAGE [initandlisten] unable to validate readahead settings due to error: boost::filesystem::status: Permission denied: "/sys/dev/block/8:2/queue/read_ahead_kb"

I see that it could be a kernel problem or a permission problem.
I try to change permission but nothing happens.

What do you think it can be? How can I solve this issue?

Thanks
