#36 fail to run on some machine/platform

[sunzen.w]

I try to use the 2004.7.30-post version. It works on
one machine(Red Hat8.0, 3ware-9500 raid controller).
But there are problems when it is run on another
machine(RHT advance server3.0, arcmsr Raid). When
start test, a error dialog box appear and dynamo
segmentation fault.

The message of dynamo is as the following:

ot@fengshuo src]# ./dynamo -i 10.10.5.12 -m 10.10.5.117

Socket error 10053 means: TCP/IP Connection Aborted by Peer

so where is u iometer? what happens on iometer? and do u
have firewall on it?

It seems not because of network configuation, for iometer
and dynamo have had communication.
It seems Ther error just happens when dynamo start to do
the I/O.
Today I changed the platform from RedHaT advanced
server3.0 to Redhat 8.0, the problem disappear and Iometer
run well.
Thanks.

I thought it was a litter bug of iometer 2004.07.30. you should
edit file IOCommon.h ,and change the line
#define BLKGETSIZE64 _IOR(0x12,114, unsigned long long )
to
#define BLKGETSIZE64 _IOR(0x12,114, sizeof (unsigned
long long) )

see usr/include/asm/ioctl.h

#define _IOR(type,nr,size)
_IOC(_IOC_READ,(type),(nr),sizeof(size))

so u can not do sizeof(sizeof())
