Hi Everyone! I just setup a lustre system on centos 5.5 and lustre 1.8.5. there are three identical oss with four osts each.
After having fantastic write rates but low read rates, I ran the obdfilter-survey script to get a hint of what may cause this. Unfortnately obdfilter-survey in case=disk mode freezes on two of my three oss at the write task of the 4 objs, 16 threads line and leaves the system in an unstable state requiring a reboot. The other oss runs through the script without problems. To exclude a problem in the system´s setup, I booted one of the bad oss with the working oss´ disk - with the same faulty result. Creating a new filesystem on all osts of one of the problem oss neither did the trick. Any ideas what may cause this behavior? Thanks!
