I can easily set an anchor as f:\vdbench or whatever to test workload against one file system. However I want to generate workload to multiple filesystems at the same time, say f: g:, h:, i:. Here is a parm file for one file system and I am trying to modify to extend this to multiple filesystems:
compratio=5
hd=localhost,jvms=24
fsd=filefsd,anchor=f:/vdbenchFS/,count=(1,4),shared=yes,depth=5,width=5,files=1024,size=1m,total_size=100g
fwd=filefwd0,fsd=filefsd*,fileio=random,fileselect=random,xfersizes=(4k)
.
.xfer size is just skipping 4,8,16,32,64,128,256,1024
.
fwd=filefwd7,fsd=filefsd*,fileio=random,fileselect=random,xfersizes=(1024k)
rd=filerd0,fwd=filefwd0,fwdrate=max,formate=restart,foroperations=(write,read)forthreads=(32,48,64),rdpct=(60,80,100),elapsed=180,interfal=15,warmup=15,pause=15
.

rd=filerd7,fwd=filefwd7,fwdrate=max,format=restart,foroperations=(write,read),forthreads=(32,48,64),rdpct=(60,80,100)....etc...etc. like above
