pvcreate not locating drive

[mohnkern]

I recently installed a SATA drive on a SYBA controller.

I partitioned the drive as a 500 GB partition type 8e (LVM) then ran mke2fs -j /dev/sda1 to write the file system,

However, when I run sudo pvcreate /dev/sda1 I get the following error:

 Device /dev/sda1 not found (or ignored by filtering).

here's the result of and fdisk -l

mohnkern@Casa-Scott:~$ sudo fdisk -l

I read in one bug where one should try doing a

dd if=/dev/zero of=/dev/sda

to blank out the partition table, and then run pvcreate.

I tried that, received the same error.

Just as a test, I made the drive a normal Linux partition, and I was able to mount to it and create files, so I doubt it's the drive.

There doesn't appear to be anything regarding an error in /var/log.

and a fsck comes up clean:

 Device /dev/sda1 not found (or ignored by filtering).

I ran dd if=/dev/zero again and then attempted a pvcreate without installing a partiion, and it still is generating this error.

I discovered the problem.

The default lvm.conf file (/etc/lvm/lvm.conf) contained the following line:

filter = [ "a|/dev/hd[ab]|", "r/.*/" ]

This had to be changed to:

filter = [ "a|/dev/[hs[d[ab]|", "r/.*/" ]

or commented out.
