Re: Using parted to resize partitions in a Woody HPPA system

Hi everybody,
My system has one 4GB HD (/dev/sda). At the moment, /dev/sda7 (/var)
partition has almost 2GB, while /dev/sda6 (/usr) partition is just
0.9GB wide - ok, its weird, don't ask... I intend to use parted to fix
it. So I got some hints from parted manual and imagined the following
procedure:
hmm I have no experience with parted but don't you have to umount /var
and /usr fs before all?
It is not clear in 'man parted' but it shouldn't be a pb as parted stand
in /sbin (and more safe? )
May be should you operate in single user mode to be able to umount /usr
(iirc add option -s after the name of your kernel into interactive palo
before:
0:
3/vmlinux
1: root=/dev/sda5
[...]
when:
3/vmlinux -s
after:
0: 3/vmlinux
1: -s
2: root=/dev/sda5)
1. List current partition table: parted>p
minor start end type filesystems flags
1 0.030 96.632 primary boot
2 ...
........
5 ...
6 1100 2000 logical ext2
7 2000 4000 logical ext2
Shrink the /var partition (it's the last one) by 1.5GB : parted>resize
7 2000 2300
That is the most dangerous without backup !!!
My /var is about 40Mb and and backup like 'tar cjspf
/SomeOtherFS/Var.tar.bz2 /var' could be reduced to 10Mb.
So you could certainly find a place for such backup (not /var and not
/usr :) )? (important because /var contains the dpkg db !!)
Or don't you have a remote system to make such backup?
2. Make a new partition at the end of the disk, big enough for the new
/var: parted>mkpartfs logical ext2 3700 4000
3. Copy the old (shrinked) /var (/dev/sda7) to the new one: parted>cp 7 8
4. Remove the old one: parted>rm 7
5. Grow /usr to occupy new open space: parted>resize 6 1100 3700
6. Exit: parted>quit
No changes will be needed in fstab, because the partition numbers
didn't changed.Also, root and boot partitions weren't touched, so I
think that I won't have any problems with the bootloader.
yes
So, proceedand reboot system, and that's it.
At this time I have no media do make backup disk images, and I want
avoid reinstalling all stuff again (data is already safe), so this
must work in the first try. Any comments? Anyone?
Thanks a lot,
Joao Roscoe
Good luck,
Joel
PS: For my own I have enough with /var of about 250mb
