[SOLVED] How to resizing sda4

Summary:

change drive from 1.0 to 1.5TB

help: resize sda4

tomas123 20 Mar 2011 22:21

I cloned my drive from 1TB to WDC WD15EADS-00P (1.5 TB)
All works fine but My Book Live dont't use the extra drive space from 1.0TB to 1.5TB

Now I want to resize sda4.

parted manpage wrote http://manpages.ubuntu.com/manpages/maverick/man8/parted.8.html

KNOWN ISSUES
       ext3  filesystem functionality does not currently work.  To manage ext3
       type filesystems use tools like resize2fs(8) or mke2fs(8)

I tried this way:
http://ubuntuforums.org/showthread.php?t=1389429

* Run parted on your device: parted /dev/sdX
    * Change display unit to sectors: unit s
    * Print current partition table and note the start sector for your partition: p
    * Delete your partition (won't delete the data or filesystem): rm <number>
    * Recreate the partition with the starting sector from above: mkpart primary <start> <end>
    * Exit parted: quit
    * Check the filesystem: sudo e2fsck -f /dev/sdXX
    * Resize filesystem: sudo resize2fs /dev/sdXX

but parted don't touch sda4
here my log

I have a problem which I suspect is strongly related to this one.

The ext4 filesystem uses a weird blocksize (64kB). I can't persuade a standard 64bit or 32bit Debian squeeze install to even mount this. I think this oddity will be why parted is failing.

There's a couple of potential solutions I can see. One would be changing the blocksize to a sane value, something like 4kB. The other is reformatting sda4 to either ext3 or a more conventional ext4. I'm inclined towards the latter, which would also solve your problem. That is, delete the current partition and make a new one which fills up the available space.

However, the mount scripts have thrown me. There's no reference to sda4 in /etc/fstab. I think the answer lies in /etc/init.d/mountDataVolume.sh which has some interesting bits about restoring to factory settings, during which the volume is reformatted. It may be possible by altering this script slightly to hit "restore to factory defaults" and have the drive sort itself out for you.

edit: At the moment, it looks like simply reformatting the thing will go OK. If you've still got the original image, so you can restore it to the current state if it cocks up, I think that's well worth a try. I'm waiting on a second drive to turn up before doing this myself.

Seems like it all most worked. I guess all I need to do is:

5 1000GB 3001GB 2000GB primary

Get them 2 as 1.

Should I say Yes to "WARNING!!! The filesystem is mounted. If you continue you *WILL*
cause *SEVERE* filesystem damage."?

Or what else can I do?

If you look in freshInstall.sh, WD unmounts :

# unmount DataVolumes
umount /CacheVolume 2> /dev/null
umount /nfs 2> /dev/null
umount /shares 2> /dev/null
umount /DataVolume 2> /dev/null

Then may be /dev/sda4 will be fully unused.

Re: help: resize sda4

RaymondDay 13 Nov 2011 09:22

Yes. You get the "Error: Partition /dev/sda4 is being used." because of "mountDataVolume.sh" started on boot.

I installed webmin and in there it's easy to tell "mountDataVolume.sh" to not start on boot up. Then you can "rm 4" after you boot back up. After you are done then use webmin again to tell "mountDataVolume.sh" to start on boot.

What's the best way for cloning the disc? I got a 1TB MBL and want to upgrade it to 2TB. MBL is fresh.
I've got a Win7 and an Ubuntu 10.10 on my machine ( 2 SATA ports free :-) ) - I'm new in Linux and I used to clone drives with Norton Ghost (Windows systems only), don't know if it would do it with a Linux sys-partition too.

Thanks for help!

Which variant do you have chosen?

Ben26 22 Apr 2011 08:11

I simply put both discs into my desktop-pc and cloned the 1TB to the 2TB using 'dd'. Worked fine, but needed some time…
Then I resized like above.

Just in case someone else might think about changing the blocksize. I changed the blocksize of /dev/sda4 to 4096, but when I tried to mount the filesystem later, it failed to mount.

Misi:~# mount -o noatime /dev/sda4 /DataVolume
mount: Die Datei ist zu groß

After changing the blocksize to 8192 everything works fine now:

Misi:~# mkfs.ext4 -m 0 -b 8192 -I 512 -v /dev/sda4 
Warnung: Blockgröße 8192 ist auf den meisten Systemen unbrauchbar.

Update:
After some performance tests I decided to revert the change of the blocksize to it's original value because the smaller blocksize reduced throughput with netatalk by more than 50%.
