Description Joseph Shraibman 2007-03-18 21:46:15 UTC

Description of problem:
When booting I get dropped into singe user mode when init reads fstab to mount
directories because the multipath entries in /dev don't exist.  Once I enter the
root password I can mount the directories because at that point the devices to
exist.

Version-Release number of selected component (if applicable):
device-mapper-multipath-0.4.5-16.1.RHEL4

How reproducible:

Steps to Reproduce:

Additional info:
To work around I added _netdev to the options in fstab

Comment 1 Ben Marzinski 2007-04-04 22:11:09 UTC

Which multipath entries are you using?

/dev/dm-* names are not guaranteed to be unique across reboots and should never
be used. They are also created by udev and not guaranteed to exist immediately
after device creation.

/dev/mpath/* names are unique, but are also created by udev and not guaranteed
to exist immediately after device creation. They should not be used in things
like /etc/fstab

/dev/mapper/* names are created by device-mapper, and exist immediately after
the device is created.

If you are not using /dev/mapper/* names in /etc/fstab, try switching to them
and let me know if this fixes the problem for you.

Comment 2 Joseph Shraibman 2007-04-05 01:17:58 UTC

I was using /dev/dm-*.  I can't reboot this system anytime soon just to test if
the /dev/mapper entries work.

Comment 3 Ben Marzinski 2007-06-01 00:29:55 UTC

Please let me know if this fixed the problem.

Comment 4 Joseph Shraibman 2007-06-01 01:47:33 UTC

I'm sorry, this system might not be rebooted for months.
