<p class=MsoNormal><span lang=EN-US>Two nodes cluster with exactly the same

<p class=MsoNormal><span lang=EN-US>I try to create GFS2 on 1TB LV (on the SATA
disk) with ‘mkfs.gfs2 -b 512 -t tweety:gfs2-01 -p lock_dlm -j 10
/dev/mapper/vg1-data1’<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I want to use 512 block size. Since the
command looked that it last forever, I used –D option to look on what is
going on. This visualized the fact that nothing happens after initial effort to
create Journal 3.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Because I got those freezes during mkfs.gfs2,
I used ‘vmstat –p /dev/sda1’ on a second terminal to observe
disk activity. This confirmed that there is no disk activity after the initial
effort to create Journal 3.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I thought that it might be a problem of how
I created the LV so I erase all VG, LV and PV and try to create the file system
on the physical device.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The creation of GFS2 on the physical partition
also freezes on Journal 3.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US>This is the extract of the output of ‘mkfs.gfs2
-D -b 512 -t tweety:gfs2-01 -p lock_dlm -j 10 /dev/sda1’ (which is same
to the output I get when using the LV instead of the physical partition):<o:p></o:p></span></p>
