Hi @nobobypb,
Thank you for your script, worked good so far.
But I am not sure what to do with the message at the end:
###########
If you want to remove /volume1 you should also move the following:

System service symlink /var/services/download to /volume1/@Download
System service symlink /var/services/pgsql to /volume1/@database/pgsql
System service symlink /var/services/printer to /volume1/@spool
System service symlink /var/services/tmp to /volume1/@tmp
########

I was moving from /volume1 to /volume2, so shouldnt be there /Volume2/ in the end?
and, how do I move those symlinks?

thank you for a little hint :-)

I had to replace if [ ! -e "$symlink" ]; then by if [ ! -h "$symlink" ]; then otherwise I got the "has no symlink" error for all packages, but once I had that figured out, it worked great, thanks!

Thanks for the handy script! It only had trouble moving "Plex Media Server" because of the spaces, but did that manually (spaces cause issues at multiple places in the script)

Another helpful command for changing all symlinks from /volume1 to /volume2 is:

find . -lname '/volume1/*' -printf '%l\0%p\0' | sed -z 's|^/volume1|/volume2|;n' | xargs -r0n2 ln -sfT

Sooooo just to be clear here...If I want to move everything off of Vol1 and Vol2 to be on Vol3, I'd run this script twice (changing the source each time to vol1 then vol2)? After it's done, can I then delete vol1 and vol2 and add their space to vol3?
