The freed logical extents are returned +to the VG to be used by other LVs. A copy\-on\-write snapshot LV can also +be reduced if less space is needed to hold COW blocks. Use +\fBlvconvert\fP(8) to change the number of data images in a RAID or +mirrored LV. + +Be careful when reducing an LV's size, because data in the reduced area is +lost. Ensure that any file system on the LV is resized \fBbefore\fP +running lvreduce so that the removed extents are not in use by the file +system. + +Sizes will be rounded if necessary. For example, the LV size must be an +exact number of extents, and the size of a striped segment must be a +multiple of the number of stripes. |
