Patch Name: PHCO_29905 Patch Description: s700_800 11.11 Device IDs enab, mount(1M) cumulative patch Creation Date: 03/12/05 Post Date: 03/12/17 Hardware Platforms - OS Releases: s700: 11.11 s800: 11.11 Products: N/A Filesets: OS-Core.UX-CORE,fr=B.11.11,fa=HP-UX_B.11.11_32/64,v=HP Automatic Reboot?: No Status: General Release Critical: No (superseded patches were critical) PHCO_28350: ABORT Category Tags: defect_repair enhancement general_release critical halts_system manual_dependencies Path Name: /hp-ux_patches/s700_800/11.X/PHCO_29905 Symptoms: PHCO_29905: ( SR:8606313142 CR:JAGae75940 ) mount(2) system call successfully mounts the filesystem but mount(1M) exits with an error. ( SR:8606313137 CR:JAGae75935 ) mount(1M) with no option returns incomplete list of mounted filesystems. PHCO_28350: ( SR:8606279858 CR:JAGae43847 ) mount(1M) fails to determine the filesystem type for VxFS version 4 disklayout. ( SR:8606288416 CR:JAGae52347 ) mount(1M) core dumps. PHCO_27956: ( SR:8606280658 CR:JAGae44628 ) This product update is a member of a set needed to enable the optional HP-UX Device IDs feature. Upon installation, the HP-UX Device IDs bundle (DevIDs11i) will install the full set of product updates (including this one) necessary to enable the Device IDs feature. If the HP-UX Device IDs product (DeviceIDs11i) is not installed, this product update to HP-UX will have no impact on your system. PHCO_26242: ( SR:8606236148 CR:JAGae05213 ) mount(1M) may run slowly as the number of mounted file systems increases. Defect Description: PHCO_29905: ( SR:8606313142 CR:JAGae75940 ) Filesystem specific mount(2) system call succeeds, that is filesystem gets mounted, but mount(1M) command might fail to update /etc/mnttab. Thus mount(1M) returns with an error without issuing an error message. Resolution: Retry mechanism is provided to retry updating /etc/mnttab. ( SR:8606313137 CR:JAGae75935 ) A mount process reads copy of /etc/mnttab without exclusive access. That is, mount(1M) reads the copy of /etc/mnttab which is under construction. Resolution: mount(1M) has been modified to get a exclusive access to copy of /etc/mnttab while reading. This exclusive access is granted only for root user. The non-root user will still see the documented symptoms, that is, incomplete list of filesystems. PHCO_28350: ( SR:8606279858 CR:JAGae43847 ) The filesystem metadata is read using 32 bit offsets, while VxFS with version 4 disklayout stores metadata beyond 2GB. Thus read of filesystem metadata fails. Resolution: Changed the read mode from 32 bit to 64 bit. ( SR:8606288416 CR:JAGae52347 ) mount(1M) dumps core when invoked with an argument string of more than 8500 characters long. Resolution: Changed the code to handle any number of characters sent in from the command line. PHCO_27956: ( SR:8606280658 CR:JAGae44628 ) This product update contains minor enhancements required to enable the HP-UX Device IDs feature. When AutoFS unmounts a filesystem, it obtains the device id from the filesystem server. If that server is slow, or not responding, there may be a delay of 15 seconds or more. On systems with many AutoFS managed fileystems and many slow or non-responding servers, the cumulative delay may be quite significant. Resolution: Use an archive libc that supports the HP-UX Device IDs feature. PHCO_26242: ( SR:8606236148 CR:JAGae05213 ) The mechanism used to update information about mounted file systems increases in cost quadratically as a function of the number of already mounted file systems. Resolution: Switch to a mechanism for updating information about mounted file systems whose cost is a linear function of the number of mounted file systems. Enhancement: No (superseded patches contained enhancements) PHCO_28350: Enhancements were delivered in a patch this one has superseded. Please review the Defect Description text for more information.
