Red Hat Bugzilla – Bug 606519
/dev/mapper/pdc_efihghgip1 on / ?
Last modified: 2010-06-22 03:19:05 EDT
Description of problem:
I think this is more a question then a bug.
After doing a clean install of Fedora 13 on a system with two disks in a raid1 configuration on a Fasttrak Tx2000 firmware/bios fake raid controller (yeah I know that's cheap), the file system is mounted on /dev/mapper/pdc_efihghgip1.
Is this supposed to be so?
I mean, when I look at the output of the dmevent_tool:
pdc_efihghgip2 not monitored
pdc_efihghgip1 not monitored
pdc_efihghgi not monitored
I see that both disks are being displayed as pdc_efihghgip1 and pdc_efihghgip2, but what is then pdc_efihghgi ?
Is that the actual raid device? And is it not supposed to be mounted instead?
It is not clear to me how things work in this case and I searched for more information but failed to find any.
Version-Release number of selected component (if applicable):
How reproducible: Allways
Steps to Reproduce:
1. Install F13 on fasttrak mirrored array.
Actual results: / mounted on /dev/mapper/pdc_efihghgip1
Expected results: / mounted on /dev/mapper/pdc_efihghgip ?

I think so too, so let me answer it and then close this bug :)

This is really quite simple,
Is the entire set, just think of it as a virtual disk and just like a real disk
it has a partition table and partitions on it.
is the first partition usually (*) this contains /boot and is mounted as /boot
Is the second partition usually (*) this contains one big physical volume on top
of which a Volume group is build which contains logical volumes for
/, /home and swap.
*) usually means when you used auto partitioning during the installation if you did a custom install things can be very different.
