PHKL_21491: ( SR: 8606132674 DTS: JAGad01822 ) JFS 3.1 fsadm could hang while defragmenting large VxFS file systems. Defect Description: PHKL_28632: ( SR:8606288455 CR:JAGae52386 ) If writes to a file are non-sequential or random, as in the case with NFS and sparse files, VxFS may fail to get an extent of a certain size when writing to a hole due to excessive fragmentation. Resolution: VxFS now manages the file on disk layout three and above such that writing to a hole in the file can allocate multiple smaller sized extents. PHKL_21491: ( SR: 8606132674 DTS: JAGad01822 ) While reorganizing the extents of a file with a HOLE, rounding up the extent size was not done correctly since an argument was used incorrectly, causing the extent reorganization to loop. Resolution: Cast the argument to the correct type while rounding up the extent size.
