After this, the computer could still be pinged, but every
shell or ssh access was not functioning any more. I suppose
the vfs layer was dead. To get it working again, I had to
switch off.
I tried the same setting once again and got after around one
hour:
The machine crached with:
Panic String: ffs_clusteralloc: map mismatch
If you need more info (e.g. vmcore from 2nd run), please give
me a note.
>How-To-Repeat:
Using the following load it crashed after around one hour:
Two concurrent tar from external machines, on the target
machine a trafshow, two gzip (from external tar via ssh):
$ sudo tar cf - . | ssh giga gzip \> /mnt/oli/backup/guppy.tgz
$ sudo tar cf - . | ssh giga gzip \> /mnt/oli/backup/buster.tgz
If you need some more tests, I would like to support by testing
with a patched kernel or potential different hardware.
