How are reserved GDT used after online -resizing?
I am working on Ext3 and after looking at FS layout - ext3 reserves ~1024 blocks as Reserved Group Descriptor Table (reserved GDT blocks are between Group Descriptor blocks and Bitmap blocks). These blocks are used once we do online resizing. I was wondering - how these reserved blocks are used after online resizing is done? Are these free blocks used as data blocks or they can be used for other purposes as well? Also, what is the impact (apart from the fact that online -resizing will not work) if we don't leave any room for reserved GDT?
