Re: [Moosefs-users] starting chunkserver

[Michal B. <mic...@ge...>]

Hi!

 

You cannot use 127.0.0.1 as IP of chunkservers.

 

Regarding the speed while starting - you have 5 million chunks on one disk -
it has to take some time :) Scanning is made in parallel on several disks,
so if you have any RAID, it would be better to switch it off and use the
disks individually.

 

On the other hand, we did speed it up in 1.6.22 (not yet released), as we
read file attributes in a lazy way - upon the first request.

 

 

Kind regards

I don't get the error message. What's the problem with the host name, where
and how should I use IP address? 


Well, I moved mfsmaster entry in the hosts file from 127.0.0.1 to the
external IP address, and now it works:

$ /etc/init.d/mfs-chunkserver start
Starting mfs-chunkserver: working directory: /var/lib/mfs
lockfile created and locked
initializing mfschunkserver modules ...
hdd space manager: scanning folder /data/ ...
hdd space manager: scanning complete
hdd space manager: /data/: 5122835 chunks found
hdd space manager: scanning complete
main server module: listen on *:9422
stats file has been loaded
mfschunkserver daemon initialized properly
mfschunkserver.


But if it's possible, it's starting far more slower while scanning. It's
really-really slow. Why? Is there any way to speed it up?

Thank you,
