Comment 3 for bug 598696

I was pleased to see you coming back to me. Unfortunately, the
headless server suffered from inadapted power cycling, resulting in
damage on the RAID array and a non bootable system. I managed to
return it to a bootable state, but thousands of files are damaged and
ssh access doesn't work. It is presently waiting for a full backup of
user data, before a full reinstall.

I will do these tests when I have time, and when a more convenient ssh
shell becomes available.

I'll keep you informed. I am familiar with the tools and processes
evoked in your message (apport).

Best regards,

JM Le Peuvédic
