Hi,

I'm trying to copy over some 700Mb of data from one hfs-disk-image to
another. Both are mounted through the "loop" device. (Using -o loop on
the mount command)

By now I've seen several lockups due to trying to copy that data.

Using "tar" or "cp -r" causes the lockup, using "rsync" takes much
longer to trigger it.

I'm running:

Linux version 2.2.15pre3 (wolff@cave) (gcc version egcs-2.91.66
19990314/Linux (egcs-1.1.2 release)) #3 Fri Feb 4 15:59:32 MET 2000

When the lockup occurs, one of the processes ends up in "disk wait"
and stays that way. The first "sync" issued also hangs. Subsequent
"sync" commands return after a few seconds.

I switched to using "rsync" to be able to restart after a crash, but I
seem to be able to copy most of the data without crashing. (But I now
have one hang using rsync).

root 727 6.6 4.0 2404 1240 ? D 13:19 0:58 rsync -avvcT /tmp ...
root 728 1.2 0.0 0 0 ? Z 13:21 0:08 (rsync <zombie>)

Roger.

P.S. I'm not in a hurry to have this fixed. I'll manage with the
current state of affairs. Just an item for someone's TODO list. ;-)
