It's lvm2, which I have been successfully using for some years not just
on this machine but on others as well.

One other thing to note is that all of the filesystems on this machine
are JFS (except /boot).  The filesystem impacted is the second-largest
and second-busiest JFS filesystem.  The largest and busiest JFS
filesystem uses LVM as well.  Other JFS filesystems (/var, etc.) do not
use LVM.

I have never had any problem with the other JFS filesystems.  It's
always been this particular one that gives me trouble.

Good point.  I will probably do that on Sunday and I will try to
remember to keep you informed here.
