What's the best way to accomplish this safely? I know that I need to create a partition for each of these, temporarily mount it, cp the files, test the copy, delete the files from the original location and then remount to the (now empty) original directory.
so as an example I'm thinking to move the /public directory
1) Fdisk to create partitions and make filesystems 2) sudo mount /dev/hdcx /mnt/temp 3) Stop samba, atalk, cron services 4) sudo cp -al /public /mnt/temp 5) test somehow that the copy worked. Suggestions? 6) sudo rm -Rf /public/* 7) restart services
Without addressing any of your other questions, I'd like to give some advice on the copy. Most people accomplish this type of tree copy not with the cp -R command, but with either tar or cpio. The reason is that these archiving utilities really do a good job with ownership, permissions, timestamps, hardlinks and symlinks.
The following script is my cptree command, that copies a tree from one
place to another. I've used it in my backups for years, and as far as I
can tell it works perfectly. Mine uses tar, but you can do something
similar with cpio.
#=========== Start of script, delete this line =============== #!/bin/bash echo Tree copying $1 to $2 sleep 2 tar -cvf - $1 | tar --atime-preserve -C $2 -xf - #=========== End of script, delete this line ===============
I have something similar in my toolbox:
#!/bin/sh
if [ -d "$1" && -r "$1" ]; then
if [ -d "$2" && -w "$2" ]; then
cd $1
find . -print -depth |cpio -pdumanV $2
exit 0
else
echo "Writable destination directory not specified"
fi
else
echo "Readable source directory not specified"
fi
echo "USAGE: $0 _location_of_old_directory_ _location_of_new_directory_"
echo " or"
echo " $0 _location_of_old_directory_ _mountpoint_of_new_partition_"
exit 1 - the "-depth" find flag causes directories to be listed after their
files, upon which the "-ma" cpio flags reset the permission and
access times of the directories after the files are copied in it - I prefer _cpio_ over _tar_ for this, but either way, just make sure
to set to copy links, not follow them, and to copy special files
