no need to tar the files

why do you go the complex way if you have the simple way?

sudo cp -rp anything to/new/location

the key is the -p parameter in the cp command, that preserve file permissions and the r made it recursive, so each file is copied recursively preserving its own permissions

but, i have to admit to tar the files will give you an extra backup

Using tar is better than copy when moving files like this. That way you leave file perms the same.

Don Long’s advice worked for me. Thanks

“You should also move the ibdata1, ib_logfile0 and ib_logfile1 files. If you don’t all your InnoDB tables will be gone.”

Those files get recreated at the new location on rebooting.
