Can you run df without any arguments? Could be a rounding issue in
df.<br>
Still unsure how ocfs2 install/deinstall could trigger that.<br>

<p class="MsoNormal"><span lang="EN-US">When I discovered the
mismatch, I stopped ocfs2, deinstalled version 1.4.7 and
reinstalled 1.2.9 on both nodes. When mounting the disks
again, the sizes was the same and the same as node1 when
running 1.4.7. When I’m writing this, I can see that not
only the ocfs2 disks are different. I see that also the OS
disks on ext3 file system is different. When I check them
against the nodes now, it’s all equal and no differences.
Has anybody experienced something like this? There was no
reboot between the deinstallations and installations of
ocfs2.<o:p></o:p></span></p>
