I just added bigger 4TBfrom 2TB ssd to the md0 raid but the size is still the same. I tryed to resize .partition but it says it is busy. Parted is still resizing it on old size.
array:
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]
md0 : active raid1 sdb2[3] sda2[2]
1875210240 blocks super 1.2 [2/2] [UU]
bitmap: 3/14 pages [12KB], 65536KB chunk
Any idea what I am doing wrong? Thanks
