6.13. Resizing a RAID logical volume
You can resize a RAID logical volume in the following ways;
-
You can increase the size of a RAID logical volume of any type with the
lvresizeorlvextendcommand. This does not change the number of RAID images. For striped RAID logical volumes the same stripe rounding constraints apply as when you create a striped RAID logical volume.
-
You can reduce the size of a RAID logical volume of any type with the
lvresizeorlvreducecommand. This does not change the number of RAID images. As with thelvextendcommand, the same stripe rounding constraints apply as when you create a striped RAID logical volume.
-
You can change the number of stripes on a striped RAID logical volume (
raid4/5/6/10) with the--stripes Nparameter of thelvconvertcommand. This increases or reduces the size of the RAID logical volume by the capacity of the stripes added or removed. Note thatraid10volumes are capable only of adding stripes. This capability is part of the RAID reshaping feature that allows you to change attributes of a RAID logical volume while keeping the same RAID level. For information on RAID reshaping and examples of using thelvconvertcommand to reshape a RAID logical volume, see thelvmraid(7) man page.
