Hi again!
Same setup as before (Lustre 1.6.2 + 2.6.18 kernel).
This time things suddenly started to be very slow (as in periodically
stalling), and we found a bunch of llog_ LustreErrors on the MDS. Some
time later stuff had automagically recovered and is back to normal
speed.
Any idea on the meaning/cause of these errors?
What are the seriousness of "LustreError" errors in general? Does it
mean "this is bad, but normal", "this is bad, shouldn't happen" or
"you've found yet another bug"?
