Hi,
I recently update lustre to 1.8. In order to avoid problems in the
update I install from the begining all the stuff (SO, lustre, ...). My
system is based on a Debian Lenny with the kernel 2.6.22, patched
without problems. I setup 1 mgs/mdt and 2 ost in 2 servers (one for
mgs/mdt and ost, and another for ost only).
I''m doing some test to verify the robustness of lustre in case of
random
crashes of the server or network, in this case I have a down ost and
when I remount the ost, it enters in recovering status. At this moment I
send to server a "reboot" and it crash dumping this message:
LustreError: dumping log to /tmp/lustre-log.1242667129.4109

Can you tell me the reason? or solution?
I have some experience with lustre but i''m very confussed with the new
version.
Thank you in advance!
