Expand LSI array using StorCli

This is a short guide how to expand an LSI array when adding more discs and expand the filesystem

Add the new drives

sudo /opt/MegaRAID/storcli/storcli64 /c0/v0 start migrate type=raid6 option=add drives=13:9,13:10,13:11,13:12,13:13

Set a bit faster rebuild rate (Optional)

sudo /opt/MegaRAID/storcli/storcli64 /c0 set rebuildrate=80

Reboot the system after the rebuild is done. after a week or so…

sudo reboot

Unmount the filesystem

sudo umount /dev/sdb1

Grow the partition on the now larger array

sudo parted /dev/sdb
	-	"print" and answer "Fix"
	-	"resizepart" partition 1 and set end to "-1"
	-	"quit"

run a filesystem check update it on its new partition information

sudo e2fsck -f /dev/sda1

Resize the filesystem

sudo resize2fs -p /dev/sda1

Remount the drive

sudo mount -a

DONE!
