+Bugzilla : 12181, 12203
+Description: data loss for recently-modified files
+Introduced : 1.4.6
+Details : In some cases it is possible that recently written or created
+ files may not be written to disk in a timely manner (this should
+ normally be within 30s unless client IO load is very high).
+ The problem appears as zero-length files or files that are a
+ multiple of 1MB in size after a client crash or client eviction
+ that are missing data at the end of the file.
+
+ This problem is more likely to be hit on clients where files are
+ repeatedly created and unlinked in the same directory, clients
+ have a large amount of RAM, have many CPUs, the filesystem has
+ many OSTs, the clients are rebooted frequently, and/or the files
+ are not accessed by other nodes after being written.
+
+ The presence of the problem can be detected by looking at
+ /proc/sys/fs/inode-state. If the first number (nr_inodes) is
+ smaller than the second (nr_unused) then dirty files will not
+ be flushed automatically to disk. "sync; sleep 10" should be
+ run several times on the node before unmounting it to update
+ Lustre (this is also safe to run on nodes without this problem).
+
+ There is also a related kernel bug in the RHEL4 4 2.6.9 kernel
+ that can cause this same problem, so customers using that kernel
+ also need to update the kernel in addition to Lustre. In order
+ to properly fix this bug, the RHEL3 2.4.21 kernel is also updated.
+
+ It is normal that files written just before a client crash (less
+ than 30s) may not yet have been flushed to disk, even for local
+ filesystems.
