BUG IN REISERFS SLES 10 :

[Masthan, Dudekula (STSD)]

Hi Folks,

I am using SLES 10 latest beta bits. Generally I will use sg_reset
command to reset my scsi device/bus. In sles 10 the machine is not
coming up ( or in otherwords the machine is hanging)  after issuing the
sg_reset command.
I tried the following command

# sg_reset -b /dev/sg3

and also i tried with scsi ioctls, still I am facing the same problem
I tried with the following standalone program

#include<stdio.h>
   :
   :
int main(int argc, char * argv[]) {
   int fd;
   int rc;
   int arg=2;
   if ((fd=open("/dev/sg3", O_RDWR)) < 0) {
      printf( "device open fails");
      return -1;
   }
   if ((rc=ioctl(fd,SG_SCSI_RESET,&arg)) < 0 ){
     printf( " ioctl failed "); 
     close (fd);
     return -1;
   }
  
  printf ( " reset success ");
  close (fd);
  return 0;
 }


After running above program also I am facing same problem. 


Is it bug in SLES 10 or is it bug in qlogic driver ?

Thanks in advance

To check whether it is filesystem problem you may want to try something
like:
mknod /ext2-mount/sg3 c 21 3
and then try your program patched with the below:
- if ((fd=open("/dev/sg3", O_RDWR)) < 0) {
+ if ((fd=open("/ext2-mount/sg3", O_RDWR)) < 0) {

Hi Folks,

Mkreiserfs command is failing by showing " There are no enoguh blocks on
this device" , What is the minimum size of a disk to create reiserfs
file system

Please choose your subject carefully. Claiming that you found a bug in
reiserfs while you only met a boundary condition isn't very polite.

That mainly depends on the journal size. The default journal size is 32
MB which means that an actual useful disk size is about 100 MB. See
mkreiserfs(8), -s option.
