I have a system with a raid 5 array which I have extended using HP

However because of the limited size of the extended partition I am
unable to use the extra space, I receive the following error:
Command (m for help): n
No free sectors available

Presumably I have to remove partition 5 and also the extended
partition 4, then resize the extended partition to use the extra
space. However I'm concerned that I'll loose all the data on partition
5, is there a way around this? I am wondering if I specify the start
and end cylinders of partition 5 to be the same size will the data be
preserved?
In my experience if you have the starting position as before, all should
be fine. Delete partition 5, delete partition 4, create the new
partition 4, with the old start and the new end, create the new
partition 5 with the same start cylinder for partition 5 with a new end
cylinder and then run ext2online (RHEL/CentOS
4) or resize2fs (RHEL/CentOS 5) to extend the filesystem. As always,
standard rules apply. Backups are good, more backups on different
systems / disks are better.
Hope this helps.
