请教:lvcreate如何将lv创建到制定disk上面??
# vgdisplay -v vg00
PV Name /dev/dsk/c1t0d0s2
PV Name /dev/dsk/c1t1d0
# lvcreate -L 8 -n mylv00 vg00
如上 vg00下面有2个disk
请教:在创建mylv00的时候,如何把mylv00指定到/dev/dsk/c1t1d0上面呢???

lvcreate -n mylv00 vg00
lvextend -L 100m /dev/vg00/mylv00 /dev/dsk/c1t1d0
先创建LV的名字,没有大小,然后将该LV扩展到目的PV上去,并指定大小(小技巧)
具体参看man
If you omit the -l and -L options, the logical volume is created with
zero length. This permits you to choose its physical volume location
when you allocate logical extents with the lvextend command (see
lvextend(1M)). If you specify -l or -L, the location is determined
automatically.
