ext4, extundelete needs fs umounted right? and would restore to another fs, that wont work for me.
The deleted are big files, if umounting and restoring on another filesystem I would have to copy back to the original fs.
So, I wonder if there is some way to just restore on the mounted filesystem, and to the mounted fs. I read there could have a way to "re-link" the deleted files, but we would need to know the deleted inode, and nothing is listed by debugfs -w. Any other idea?
Actually I dont really need to keep it mounted, just that the files are restored direcly on the same FS, if it could be done umounted would work too.
Edit: by what I read here https://unix.stackexchange.com/a/266107/30352 it is impossible with ext4!
