Root filled when tarring /home

aragon127 · 10-15-2006, 12:22 PM

I was trying to expand my /home directory by moving it to a new drive. I added the new drive, mounted it as home and did cd /home;tar cvf - .|(cd /newhome;tar xvf - .)

Unfortunately, it filled up by root drive. I can't find specifically where though. I cleaned out all the temp directories, the trash etc, but it still says 100% usage. What do I do?

Search the root file system for the name of a directory that is in the /home directory. That will tell you where the tar command put the files. If you had a directory in /home named abe then you would enter this command.

Code:

find / -mount -name abe

The -mount parameter prevents the find command from looking on other file systems.

Is there any specific reason or performance gain when you are using tar to tar the files in old /home directory and then, pipe it into tar again to extract into the new /home directory ?

I would use cp command to do that !

"cp -a ..." is definitely the way to go.
To check for where the space has gone try

Code:

du / -x | sort -nr | less

Could take a while.

Well, I've successfully moved home. Now I have space to extend root.

I reformatted the old /home. I chose (via diskdrake) to create it as an extension and mounted it in /usr. Is that what I wanted to do?

I did a search for files from my old home and the only place they turned up were the old one.
