Hi Diego,

i noticed, when i move files from broken volume to new mounted gf volume, the folder and files are also deleted from .glusterfs directory. Thats ok right, because there are the hardlilnks of the files, right? You wrote, that you delete the .glusterfs Folder first and than move. I didnt try it because iam afraid of loosing all files, if these are the hardlings. I also noticed, if i moved files and the folder and files are also deleted in .glusterfs, the disk size didnt change.

=> i read about hardlink and it seems that there is a remaining part of them, thats why the free space rises, right? So i have to delete the .glusterfs directory right and no "real" files are deleted. Thats what i understand now by reading about hardlinks.

What do you think
thx
