I am not sure yet.  I have not tried that.  The last crash took longer
to happen.  Here is the info:

shells/bash/files/
shells/bash/files/extrapatch-colonbreakswords
shells/bash/files/extrapatch-implicitcd
shells/bash/files/extrapatch-import-functions
Read from remote host 199.89.147.183: Operation timed out
Connection to 199.89.147.183 closed.

And the error from the console when that happened:

login: mode = 02, inum = 804008, fs = /export
panic: ffs_valloc: dup alloc
KDB: enter: panic
[ thread pid 1047 tid 100089 ]
Stopped at      $d.7:   ldrb    r15, [r15, r15, ror r15]!

Now the above and the backtrace:

So looks like it took 5 hours to crash on that rsync.

Now I will write zeros until I fill the partation or the box crashes.
