I see a two possible problems with your command to create the tarball: tar
zcvf backup.tgz /usr/local/data/*
1. You must have GNU tar for this to work.
2. This command will *NOT* backup up any hidden files
(instead try tar zcvf backup.tgz /usr/local/data /usr/local/data/.[0-z]
*)
Also, I don't believe you can have two entries in /etc/filesystems with the
same mount point (/usr/local/data) so you might have to fiddle with step 3.
Other than that I think your process will work fine but I think you could
save yourself some time by mounting both filesystems at the same time and
just copying the data from the old filesystem to the new filesystem. (saves
having to create the gzipped tarball)...
0. stop the running program which need in this filesystem
1. umount the filesystem (umount /usr/local/data)
2. change the filesystem mount point (chfs -m /tmp/data /usr/local/data)
3. mount the old filesystem (mount /tmp/data)
4. add a new filesystem in other VG, and mount it to /usr/local/data
5. migrate the data:
cd /tmp/data
find . -print | cpio -pdmu /usr/local/data
6. check the file are ok,
7. re-start the program and test it ok
8. delete the LV (usage by old filesystem) and it will release the hdisk
space
