chvg -t 参数

jstang

man chvg看到有这么一个参数
-t [factor] Changes the limit of the number of physical partitions per physical
volume, specified by factor. factor should be between 1 and 16 for 32 disk
volume groups and 1 and 64 for 128 disk volume groups.
后面
32 disk volume groups and 128 disk volume groups. 指的什么,
个人理解 factor越大, disk数越小才对，？？？//
man chvg
看-G、-B参数
是反比关系
If a factor value is used, a maximum of MAXPVS/factor disks can be included in the volume group.
WORK的意思：
To change the maximum number of physical partitions per physical volume to 2032 and maximum number of physical volumes in volume group vg03 to 16,
type:
chvg -t 2 vg03
原来t是1，最大PVs是32。现在t是2，最大PVs是16。
一个VG中最大的PP数量=1016X32 ??是这样吗??
如果是BIG VG ,哪就是 1016X64 ??
