‘lfs mirror read’ has a -o/--outfile option that you can specify the output file that the contents of the mirror will be saved to. Yet, we get an error when we try to save a mirror to an output file. # lfs getstripe /mnt/lustre/test-framework.sh

This looks like a bug in "check_same_file()". Clearly, if one of the files doesn't exist, it can't be the same file as the other one... Patch forthcoming. |
