[linux-lvm] pvcreate error

[Yves Alloyer]

Hi Csuk,
1.0.1rc4 is not the latest. I ran into the same problem because when it sees
an md device, no matter the raid level, it thinks the device has a partition
table which is wrong. These device are always used as a whole.
To fix the problem you may either upgrade to 1.0.1 or just have a look at
the thread
"[linux-lvm] pvcreate fails on a software RAID metadisk". It describes a
patch from Luca Berra and me:

Dear All,
I made a typing error in my question. Each line of the error message is
related to /dev/md2 instead of /dev/md7.
I just installed a new system and I installed the latest 2.4.16 kernel and
the latest LVM tool 1.0.1-rc4. I established a software RAID-5 device(md)
and wanted to create a logical volume group on it(as I did with 2.4.7 kernel
on another system). However, when I issued the command I got the following
error:
# pvcreate -v /dev/md2
pvcreate -- locking logical volume manager
> pvcreate -- checking physical volume name "/dev/md2"
> pvcreate -- getting physical volume size
> pvcreate -- checking partition type
> pvcreate -- creating new physical volume
> pvcreate -- setting up physical volume for /dev/md2 with 0 sectors
> pvcreate -- ERROR "parameter error" setting up  physical volume "/dev/md2"
I checked the archives where I saw suggestion to patch the LVM tool, but I
don´t think that is related to the latest version.
What is the problem? Should I downgrade to 2.4.7?
Thanks in advance,
Ferenc
