Re: [Moosefs-users] Questions regarding chunkservers

This is just the way as chunkserver works. It does not store any additional
information on the system disk. At every startup it scans disks with data. 

If you need any further assistance please let us know.

Subject: [Moosefs-users] Questions regarding chunkservers

Hi,
I'm looking at the pros and cons of using MFS in our enviroment and there
are a few things that I have not found an answer too yet.

How much CPU and RAM is required for chunkservers part from the requirements
of the OS itself?

How much info does the chunkserver need after reboot other than the chunks
themselves?
I'm thinking about running the OS from RAM and having the system disks only
for MFS, that would result in the chunkserver having no data available at
startup except for chunks written before reboot and the initial config.
Would this result in the chunkserver loosing all its chunks or would it
recover and just notify the master of the chunks that it finds on its
drives?

Hopefully my questions make sense.

/Oli
