Hi,

now i am a bit confused and dont know what to do?!

Situation: brocken distributed vol1 with two servers/bricks. I cant start the volume, but i have access at the storage in which the files are.
Situation2: i created a new distributed vol2 over same two servers/bricks. i mounted the new vol2 on both bricks and moved manually files and folders from old vol1 directory. The problem, the free diskspace is free up and the storage runs full.

What now? delete .glusterfs direcoties, which will free up and i can manually move files and folders from old vol1 furhter?
?!

thanks for your help

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.
