Scope: This issue affects deployments running Lustre 2.10.5 with a ZFS backend only (ldiskfs not affected). There are two known triggers: 1) Application doing page-unaligned writes (typically to a 4KB boundary) to an OST that is either low on free space or user being low on quota 2) When page-unaligned writes are generated significantly faster than OST can absorb them resulting in "write grant" dropping to 0 while userspace is performing page-unaligned writes. If the "zero grant" condition did not appear, page-unaligned writes are fine (even synchronous) because they are converted into full-page RPC writes on the wire. Recommendations: While the triggering conditions may only rarely occur, we still recommend that affected sites should immediately apply the patch for LU-11663 - https://review.whamcloud.com/#/c/33748/ - and then perform an audit to see whether any files created or written to within the time since the upgrade have been affected. This fix will also be included in the upcoming 2.10.6 release. -------------- next part -------------- An HTML attachment was scrubbed...

You can also grab the source from git. There are a number of useful bug fixes in this maintenance release but of particular note is the fix for an issue which could cause data corruption with unaligned page writes for Lustre on ZFS deployments (LU-11663). We recommend anyone who is running Lustre on ZFS on Lustre 2.10.5 to upgrade to 2.10.6 immediately. All other versions of Lustre and Lustre on ldiskfs deployments are not exposed to this issue. In addition, there are the following notable enhancements over 2.10.5: RHEL 7.6 is now supported for servers and clients (LU-11525) Mellanox OFED 4.5-1 is now the default version built and tested Details of changes since 2.10.5 can be found in the 2.10.6 change log.
