If i delete 2 and recreate it starting at the same sector i can't reread the
part. table.
Is there a way todo online resizing?
Only when no partition is open. That is one reason why LVM is an
improvement over partition tables. You don't have to use a partition
table, just use the entire device as a PV. However, most admins use a
partition table with a single partition so that other OSes will
recognize the disk as in use (and hopefully not overwrite without
warning if accidentally presented).
If you have multiple drives, you might be able to migrate stuff off,
remove the PV, resize, add the PV back to the VG.
I use software RAID1/RAID10. You can remove the partition from the RAID
array, resize, then add it back and resync. Repeat for other mirror
legs to actually use the space.
