Re: Is it ok to add a new brick with files already on it?

So Gluster, at its core, uses rsync to copy the data to the other bricks.  Why not let Gluster do the heavy lifting?

In a related question... it seems, if it is possible to add filesystems already containing data, as new bricks, then it should also be possible to:

1) create empty bricks
2) add them to the gluster volume while they are empty
3) rsync data directly onto the underlying empty bricks, circumventing gluster, ie not through the gluster mountpoint
4) somehow get gluster to recognise the data that has been copied into the bricks?

How would you go about getting gluster to see the data you've rsynced directly in?
My concern would be that all the data rsynced directly onto the bricks will just sit there, invisible to glusterfs.

Thanks again for any info!

I've never added a brick with existing files but I did start a new Gluster volume on disks that already contained data and I was able to access the files without problem. Of course the files will be out of place but the first time you access them, Gluster will add links to speed up future lookups.
