Changeset 2072 in MondoRescue for branches/2.2.8/mindi/analyze-my-lvm

Timestamp:

Dec 5, 2008, 3:32:59 PM (15 years ago)

Author:

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

File:

• branches/2.2.8/mindi/analyze-my-lvm (modified) (3 diffs)
