Is there a way to "safely" resize extended partitions? I have a 2TB extended partition that has some reiserfs partitions inside and I'd like to shrink it without data loss.
Sure, full backup etc... But it's not an easy option in this case.
Can some tool like Partition Magic be used, or any other?
All competent partitioning tools will if necessary automatically resize the extended to fit the partitions that can legally be there. If there is freespace adjacent to an existing logical, that freespace should be allowed to be selected in the tool to add another as if it was already part of the extended.
Resizing an extended to a smaller size would be an exercise in futility. An extended is actually just a logical construct made up of the individual partitions it contains, plus any intervening freespace that may exist between any of them, plus the MBR partition table entry that points to the first logical partition that the extended "contains".
With that I take it that for example Partition Magic can do this? The built in tools in Linux refuse since the "filesystem doesn't support resize"... I'll make a test on another box first...
