In our ldiskfs patch sets is a critical bug which might/will corrupt the underlying ext3/ldiskfs filesystem on the OST nodes. People using our ql-releases (http://www.pci.uni-heidelberg.de/tc/usr/bernd/downloads/lustre/) should immediately upgrade to the latest version and also should e2fsck their filesystems. Sorry for the inconvenience, Bernd PS: I took over this bug from the ldiskfs patch-sets of lustre-1.6.0.1 for linux-2.6.18, so the very same bug is also present there. In bug#11039 are more recent extents/mballoc patches for linux-2.6.18 and I used these patches to fix the problem. -- Bernd Schubert Q-Leap Networks GmbH

This bug is hopefully fixed now (see https://bugzilla.lustre.org/show_bug.cgi?id=12861). Well, to discover bugs like these I''m presently extending our internal tests and run into a new problem again :( Don''t know how critical it is, though. I will post it to this list, soon. I''m also going to make a ql6-rc1 release now... Cheers, Bernd -- Bernd Schubert Q-Leap Networks GmbH

I''m a little bit confused, because I''m using lustre-1.6.0.1 on debian sarge with vanilla kernel 2.6.18.8 since a couple of weeks without any problem. (32-Bit only 1 MDS/MGS shared, 2 OSS with 3 OST each, about 40 clients) Therefore I don''t want to make things worse by applying a wrong patch. But on the other hand I don''t want to wait until I get a corrupted file system. Thanks in advance Harald
