Parted & Fdisk Problems
 

Help ......

The problem I have is with increasing / , I have tried to use parted when booting from the linux cd but I get the following:

error : Filesystem has incompatible feature enabled

Workstation is running : Red Hat Enterprise Linux WS release 4 (Nahant Update 4)
Kernel 2.6.9-42.ELsmp on an x86_64 with parted version :parted-1.6.19-4.EL. I have also tried to boot from a Ubuntu 7.04 cd which has anew version of parted (1.7 I think) but still the same.

Below is then disk info :

fdisk -l

What I am trying to do is increase /dev/sda6 from 10Gb to 20Gb???

Hope you can help??

Do you have another drive you can install in the box, or are you on a lan where you have another box with enough space? If so, the obvious way would be to rsync your root partition onto the other drive or box, fdisk the drive, make a filesystem, and rsync back. I haven't tried the magic utilities that do funny things to filesystems because the simple way is a lot safer (at least I can understand it).

Fixed it ..... & just incase anyone else has the same problem this is what I did ....

Made sure I had a backup first ..

- First had to convert the partition from a ext3 to a ext3 (tune2fs -O^has_journal /dev/partition)

- Boot off cd and go into rescue mode ..

- Use fdisk and print partition table and then make a note off the start & end cylinders of that partition and then work out what I will be changing it to.

- Delete the partition

- Create new partition but make sure it starts with the same starting cylinder .....

- save changes and then you will need to resize the filesystem to fit your new partition (resize2fs /dev/partition)

- Reboot and away you go .....

Thanks
