Lustre 1.2.8 has been released. Given the imminent release of Lustre 1.4.0, the Lustre 1.2.x series will soon come to an end. There are some significant, user-visible changes in this release: - a defect in the 1.2.7 networking code caused small messages (stat, create, etc.) to move very slowly over TCP/IP. This has been fixed. - users should notice a more accurate "mtime" during and after file writes - an issue was fixed in which the signals sent by "strace" could cause a Lustre RPC to abort too soon - if an asynchronous write fails (because a server disk has failed, for example), we now do our best to tell the application that issued the write (although it may not always be possible) - Lustre 1.2.7 contained a partial fix for problems which, in certain cases, prevented binaries from being executed properly when stored in Lustre. This introduced different problems, so this code has been removed from 1.2.8 -- mmap support has reverted to the same state as in 1.2.6. A proper fix will appear in an early 1.4.x release. - An issue was fixed which could cause a page to be incorrectly partially zeroed on the server (resulting in data loss of between 1 and PAGE_SIZE-1 bytes). This was extremely rare, and most likely when using large-page (IA64) clients to write to small-page (IA32, x86-64) servers. - Mounting Lustre could result in significantly-degraded NFS read performance on the same node, because Lustre disables kernel readahead in favour of its own. We now do this in a way that does not impact other file systems.
