Changeset 2072 in MondoRescue


Ignore:
Timestamp:

Author:
Bruno Cornec
Message:
  • Adds multipath support (as exists on RHEL 5.2)
    • analyze-my-lvm/mindi uses the /dev/mapper/mpath... entry and not /dev/dm-... entry which is not automatically created at restore time
    • Lots of mapth dmsetup commands added to deplist
    • Adds required modules to mindi
    • Fix a bug for this in mindi around real devices with /dev/mapper/mpath... names
    • init has a new StartMpath function to start multipath correctly hopefully
    • mondorestore has a new clean_multiconf function which removes /var/lib/multipath/bindings and edits /etc/multipath.conf if needed
