Increase the size of /home - restricted because of dd clone from usb stick

Ajaxual · 07-24-2014, 09:32 PM

i installed minx linux on an 8gb usb stick. i dd cloned that usb stick onto a 50gb partition (/dev/sda4).

now my /home says its running out of space - i think becasue it still thinks its on a 8gb usb stick.

fdisk -l output (windows is also installed)

If you never resized the filesystem, then yes, it's an 8GB filesystem sitting in a 50GB container. Assuming it's an ext2/3/4 filesystem, you just need to run (as root) "resize2fs /dev/sda6" and the filesystem will be enlarged to fill its partition. You can do that online, with the system running and the fileystem mounted.

EDIT: Arrrgh! I mistyped "sda4" where I should have had "sda6". Fortunately, trying to resize sda4 would have failed, harmlessly.

What does this produce - use [code] tags around your answer

Code:

df -hT

DON'T do anything to /dev/sda4

thanks. here's the output

As suggested above, you can see the filesystem is around 8Gig in a 50 Gig partition. For xfs you'll need to use xfs_growfs while it is mounted - plenty of guides online.
Whether you need to do anything for that ecryptfs container for /home I don't know.

heres the instructions that i found:

http://linux.die.net/man/8/xfs_growfs

I did the following:

Code:

xfs_growfs /dev/sda6 -d

thank you both very much for your help.

http://fixunix.com/sgi/112091-using-...ngle-disc.html mentioned that i should have used xfs_copy or xfsdump/xfsrestore to move the filesystem, rather than dd to clone the file system. This would have avoid this problem.

"dd" is almost always the wrong answer. I only use it in recovery/forensic scenarios.

jefro · 07-25-2014, 03:39 PM

Can we assume this worked? "xfs_growfs /dev/sda6 -d"
