I just got a 8Gb flash drive and went to copy a bunch of files onto it. I wanted to perserve everything, so I just took my archiving rsync command and altered it to go to localhost:/media/RALLY2/ (name of flash drive). I am getting errors with changing the group owner. Huh?
So I try to just use mkdir to create a directory on the flash drive. The directory has a group of root ???
So I try a chgrp and get:
[root@mine me]# chgrp me /media/RALLY2/Stuff chgrp: changing group of `/media/RALLY2/Stuff': Operation not permitted
OK why can't I set the group to something other than root?
ls -lstr /media/ total 4 4 drwxr-xr-x 3 me root 4096 May 30 16:28 RALLY2
and of course for /media:
8 drwxr-xr-x 3 root root 4096 May 30 16:18 media
Most likely the device is formatted as FAT32, which has no concept of permissions.
Reformat it, ignore the errors, or modify your rsync command to not preserve uid/gid.

Or if you want to preserve permissions, you will need to use tar or some other archiver.
