>I have experienced an issue when I move some files from an hdd onto gluster
volume such that one node gets overloaded in the middle of file upload.
Therefore, I decided to upload it through ssh onto other server than where
original images are store. I know that this sounds just weird, but it does not
lead to overloading!
>
>Along these lines, I decided to upload 10G image onto gluster volume and the
upload speed varied, but no overloading at all? Right after upload was done I
realized that some virtuals are not running properly. Hence I checked heal
status where I discoverd that 4 images are in split-brain state. I had to act
quickly, so I resolved the split brain, and let gluster heal. When heal was done
everything works?
