Hi,

I have a situation here where the recommended block size of the file system to be created is 2 KB and the volume layout is recommended to be stripe.

The file system to be used is Veritas File System.

Is it possible to create a striped (raid 0) volume with 2 columns and 1 KB as stripe width?

 

Platform: HP Proliant

OS: Solaris 10 x64

SF: VERITAS-5.0_x64_MP3.50

FS: VERITAS-FS-5.0.3.0

 

Regards,

Smruti Mandal

Hi Smruti,

I am wondering why you have requirement to keep such a low stwidth of 1KB .. can u elaborate on this ?

 

just FYI ..I tried this command on a test server:

 

# vxassist -g testdg make tvol 500m layout=stripe stwidth=1 ncolumn=2

& it works

$ vxprint -qthg sandg tvol
v  tvol         -            ENABLED  ACTIVE   1024000  SELECT    tvol-01  fsgen
pl tvol-01      tvol         ENABLED  ACTIVE   1024000  STRIPE    2/16     RW
sd disk72-04    tvol-01      disk72   72100864 512000   0/0       emcpower4 ENA
sd disk73-02    tvol-01      disk73   104857600 512000  1/0       emcpower5 ENA
