Hello,
I have started evaluating GlusterFS for our application to share data
and everything seems very satisfactory so far :)
I only have a few questions that are about the timeout that happens
when one of the servers goes down.
We have a simple 2 server setup with 2 replicated volumes.
You should post what version you are using and the output of 'gluster
volume info'.
About 10 clients connecting to both of the volumes and filesizes range
around a few bytes to about a coupple of megs. Its a lot of files and
folders...
Define 'a lot'. I'm soon going to migrate 83 million files to Gluster
and that's not 'a lot' compared to some others.
When one of the servers goes down all clients seems to hang for about
40-50 seconds before being able to access files and folders again.
Write operations continues during this but i guess it is being done in
memory until the file is accessible again..
What controles this timeout? Is it possible to adjust it? Is it
advisable to adjust it, if you can?
This might be what you are looking for but I don't know if it's
advisable to change it.
