\nIf looks like that, you’re good to go.<\/p>\n

15- Now add sda2 to our Raid 1 Array<\/p>\n

17- reduce and remove \/dev\/sda3<\/p>\n

vgreduce pve \/dev\/sda3

18- add \/dev\/sda3 to RAID 10 array md1<\/p>\n

sgdisk -t 3:fd00 \/dev\/sda
\nmdadm --add \/dev\/md1 \/dev\/sda3<\/code><\/p><\/blockquote>\n

19- Let our RAID 10 Array Rebuild itself. Maybe want to watch it for some fun.
\nOr speed rebuilding a little bit if you want.<\/p>\n

echo 800000 > \/proc\/sys\/dev\/raid\/speed_limit_min
\necho 1600000 > \/proc\/sys\/dev\/raid\/speed_limit_max

watch -n 2 cat \/proc\/mdstat
\n<\/code><\/p><\/blockquote>\n

20- extend our VG space and add it to our LV<\/p>\n

lvextend -l +100%FREE \/dev\/pve\/data
\nresize2fs \/dev\/pve\/data
\n<\/code><\/p><\/blockquote>\n

~~~ ALL DONE! \ud83d\ude42 ~~~<\/p>\n

21- Before rebooting don't forget to install grub one last time<\/p>\n

\ngrub-install \/dev\/sdb
\ngrub-install \/dev\/sdc
