Fixed In Version: kernel-2.6.32-131.10.1.el6
Doc Type: Bug Fix
Doc Text:
In a GFS2 file system, when the responsibility for deallocation was passed from one node to another, the receiving node may not have had a fully up-to-date inode state. If the sending node has changed the important parts of the state in the mean time (block allocation/deallocation) then this resulted in triggering an assert during the deallocation on the receiving node. With this update, the inode state is refreshed correctly during deallocation on the receiving node, ensuring that deallocation proceeds normally.
