lvextend(8) System Manager's Manual lvextend(8) NAME lvextend - Increases the number of physical extents allocated to a log- ical volume SYNOPSIS /usr/sbin/lvextend -l LogicalExtentsNumber | -m MirrorCopies Logi- calVolumePath [PhysicalVolumePath ...] DESCRIPTION This command is no longer supported on Digital UNIX systems. Features formerly provided by the Logical Volume Manager (LVM) are now provided by the Logical Storage Manager (LSM). Existing LVM volumes must be mi- grated to LSM, using an encapsulation process. For information about moving LVM volumes to LSM, see the vollvmencap(8) reference page and the manual Logical Storage Manager. The lvextend command changes either the number of logical extents allo- cated to a logical volume specified with the LogicalVolumePath parame- ter or the number of physical extents allocated to each logical extent in the logical volume. The change is determined according to which com- mand flags you use. FLAGS Increases the number of logical extents allocated to the LogicalVol- umePath. LogicalExtentsNumber must be greater than the number of logi- cal extents previously allocated to LogicalVolumePath and less than 65535 which is the implementation limit. LogicalExtentsNumber represents the new total number of logical extents that can be allocated to LogicalVolumePath. The change is accomplished by allocating the number of additional logical extents represented by the difference between LogicalExtentsNumber and the previous number of extents. The mirror policy and mirror copies number for the new logical extents is the same as previously established for the LogicalVolumePath. Either this option or the -m option must be supplied. Sets the number of physical extents allocated for each logical extent. MirrorCopies (that is, mirrors) can be either 1 or 2. This means that beyond the original copy, one or two mirror copies will contain the same data as the original copy. MirrorCopies must be greater than the current number of mirrors for the logical volume. The data in the new copies are synchronized. The synchronization process can be time consuming, depending on the hardware characteris- tics and the amount of data. If the allocation policy for the logical volume is strict and the specified physical volume already contains logical extents of the logical volume, the request is rejected. Either this option or the -l option must be supplied. EXAMPLES To increase the number of the logical extents of logical volume lv03 up to one hundred, enter: lvextend -l 100 /dev/vg01/lv03 To get two mir- rors (that is, three copies) for each logical extent of logical volume lv05, enter: lvextend -m 2 /dev/vg01/lv05 Each logical extent of logical volume lv05 is now doubly mirrored.
