How to grow raid1?
I have such configuration:
/dev/md0 Yes Mirrored (RAID1) /dev/sdb1 | /dev/sda1 - boot
/dev/md1 Yes Mirrored (RAID1) /dev/sdb2 | /dev/sda2 - /
/dev/md2 Yes Mirrored (RAID1) /dev/sdb3 | /dev/sda3 - swap
/dev/md3 Yes Mirrored (RAID1) /dev/sda4 | /dev/sdb4 - /kopia
What is the best scenario to grow md1 partition?
On test system from rescue cd I've removed md2 and md3 and sdb3-sda3 sdb4-sda4 partitions. Rebooted again from rescue cd and tried to grow md1 - but got error that there is no free space on device (I've used only 30% from md2 and md3). Why there is such error if there is a lot of free space or I am missing something?
Thanks in advance and sry for my english
