hpux_mdsetup tool is aimed at making accessing HP-UX logical volumes by Linux device mapper possible. The DM devices containing hp-vxfs file system can be read-only mounted if the included kernel 3.x patches have been applied. The patchset addresses many issues like cpu endianessnes vs ondisk big endian data and a few other things regarding inode lifetime management. Freevxfs kernel module contains all required features since kernel 4.9 has been released. Those who use HP16700 logic analyzers for R&D purposes may find this tool useful: https://sourceforge.net/projects/tv16k7/ Krzysztof Blaszkowski <kb@sysmikro.com.pl> The hpux_dmsetup was inspired by "hpux-lvm-tools" project which is valuable reference on HP-UX LVM1 internals. (and only this). 2020.03.24 Reworked code to be more compatible with Debian-based OS's by removing the echo commands when formatting table for dmsetup. Created a notification for non-sudo users that creation/removal is impossible without those privileges. Testing completed successfully on Ubuntu 18.04 LTS and OpenSUSE 42 Thanks to Keith Monahan <keith@techtravels.org> for reporting dmsetup failure, preparing proof of concept patch, verifying correctness of final solution, and valuable input 2016.06 hpux_dmsetup supports discontinuous PEs assignment to logical volumes. Single PV is required still. example (lvol4 is splitted): sudo ./a.out create -v hp16702a-ibm9gb-a.02.90.img root's password: VG Creation Time Thu Mar 27 22:09:23 2008 Physical Volume ID 78047830 47ec0d03 Volume Group ID 78047830 47ec0d03 Physical Volumes in VG 78047830 47ec0d03 VG Activation Mode 000 - LOCAL PE Size 4 MBs hpuxVG1206652163-lvol1 - 12 PE (48 MBs) at 0 (rc 0) hpuxVG1206652163-lvol2 - 384 PE (1536 MBs) at 12 (rc 0) hpuxVG1206652163-lvol3 - 250 PE (1000 MBs) at 396 (rc 0) hpuxVG1206652163-lvol4 - 437+916 PE (5412 MBs) at 646,1084 (rc 0) hpuxVG1206652163-lvol5 - 1 PE (4 MBs) at 1083 (rc 0) VG VG1206652163 Activated succesfully with 5 lvols. 2016.05 (initial release) hpux_mdsetup command line syntax follows well known dmsetup mainly. Supported commands are: create, remove, test. "hpux_dmsetup [-o aux_offset] [-v] create file" is similar to dmsetup create. Moreover it will utilize loop device in case of a file is regular file (disk raw dump) "hpux_dmsetup [-v] remove file" similar to dmsetup remove. May remove associated loop device as well. "hpux_dmsetup [-v] test file" verifies if file contains HP-UX LVM data and returns exit code with regard to verification status. -v switch increases message verbosity. No -v does not pollute stdout and exit code is the only information available. Exit code of 0 stands for success. The tool can't handle non-contiguous PE assignment to logical volume by now.
