use disk utility by loading from tiger's cd and make as many partitions as you want !!
GParted worked but I had to use Ubuntu 20.04 from x86 cause Ubuntu 16.04 PPC had crashed after boot.
I could resize Tiger and then boot successfully, but Disk Utility still crash.
Before Disk Utility couldn't delete FFS o PFS3 partitions. Only GParted can.
I 'd like to clone my Tiger partition with Carbon Copy Cleaner or CCC or save in a way I can restore it, but I still don't understand it, too many options. I get I have to format my Compact Flash to HFS+ from FAT32.
