[CALUG] Thanks again (was: Re: resizing a partition with parted, no need to preserve data?)

[Ed Browne]

Good idea.  I tried it, but it didn't affect the problem (I wish I knew
what 'parted's problem is with the filesystem it doesn't like.)  So
I just screwed up my courage and deleted the partition with fdisk.
(This of course renumbered my OS partition down from 7 to 6,
so I had to go through all the gyrations with grub to get it back
to a bootable condition.)  Then I was able to create the enlarged
new partition with fdisk, now at /dev/sda8, and put a new fs on
it.

Thanks again - Ed

I would suggest, fdisk sda and mark sda4 to "5" than "f" Once saved, try your hand at partd.

Since all slices under sda4 are Linux, Windows should not be able to see them.

Hello,
    I'm trying to clean up a balkanized hard drive by merging two
partitions which formerly held a bootable OS, /dev/sda6 and /dev/sda7.
  They are consecutive, so I deleted the second one, sda7 (note that
my current Ubuntu install was on /dev/sda8, but it became /dev/sda7,
so that one will have to be remain untouched.)  This is the partition
table now:


   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         702     5632000   27  Unknown
Partition 1 does not end on cylinder boundary.
/dev/sda2   *         702         893     1536000    7  HPFS/NTFS
Partition 2 does not end on cylinder boundary.
/dev/sda3             893        6758    47109375    7  HPFS/NTFS
/dev/sda4            6759       12161    43399597+   f  W95 Ext'd (LBA)
/dev/sda5            9215        9477     2100481   82  Linux swap / Solaris
/dev/sda6            9477       10593     8972271   83  Linux
/dev/sda7            6759        9106    18860247   83  Linux
/dev/sda8            9107        9214      867478+  82  Linux swap / Solaris


I want to expand sda6 to reclaim blocks 10,594-12,161, but nothing
I can do with "parted" works:

root at bongo:~# parted
GNU Parted 1.7.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) check 6
Error: File system has an incompatible feature enabled.
(parted) resize 6 9477 12161
Error: File system has an incompatible feature enabled.
(parted) quit
Information: Don't forget to update /etc/fstab, if necessary.

root at bongo:~# uname -a
Linux bongo 2.6.24-21-generic #1 SMP Mon Aug 25 17:32:09 UTC 2008 i686 GNU/Linux
root at bongo:~#                      

I don't need to preserve any data on /dev/sda6 (I made a new
file system several times, because I read that ext3 did not
support resizing, but the result was no better with ext2
or reiserfs.)

Can I do it with fdisk just by deleting the sda6 partition, 
and making a new sda6 partition that uses all the available
space?    Is there a smart way to do this?

Thanks in advance - Ed
