分享我的知識 : Dynamic Volume Expansion 實作

[watermelonyu]

OS:VMS8.2

Storage:MSA1000

由於MSA1000等級較差,所以做

Online擴增 Disk Volume之大小費時較久



1)擴充之前

sh dev DGX/full

可以發現total block and logical volume size 都是142255575



Total blocks 142255575

Total cylinders 28004

Logical Volume Size 142255575



2)擴充

set vol DGX:/size=142256575



3)擴充後

total block 變成Online擴增 Disk Volume實際大小

logical volume size是目前指定空間的大小



Total blocks 146448540

Total cylinders 28829

Logical Volume Size 142256575

結果:

擴充前

$ sh dev d

Device Device Error Volume Free Trans Mnt

Name Status Count Label Blocks Count Cnt

DGX: (JOEY) Mounted 1 TEST1 141523060 1 1



擴充後可以發現free space 變多了

$ sh dev d



Device Device Error Volume Free Trans Mnt

Name Status Count Label Blocks Count Cnt

DGX: (JOEY) Mounted 1 TEST1 141524052 1 1
