I have a few questions about setting up a pair of mirrored servers. Basically I have an existing user file system and I would like it to become a bit more robust. * Is there a simple way of taking an existing file-system and making it into a brick? A short shutdown to move files within the same file-system would not be a problem but copying the data to another machine would be a pain particularly because of the synchronisation issues.
As of now we have to manually sync using rsync. But auto-sync is in our road map. So you have to make sure that source file directory tree is not being modified while you do rsync.
* What happens when one machine goes down and comes back up again? There was discussion in the archives about automatic recovery in 1.4, this sounds great but what happens in 1.2? I'm thinking of both graceful shutdown and hardware failure.
As of now in 1.2, 1.3 you have to manualy fix the server which went down and bring it in sync with the server which was up. This will be done during a downtime.
* What will "features/mirror" add? I'm assuming that 1.2 will already do the basics via afr.
features/mirror is actually old name for features/afr, I will update the wiki. Regards Krishna
Thanks for all your work on gluster, it looks like the answer to a lot of people's problems! John _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxx http://lists.nongnu.org/mailman/listinfo/gluster-devel
