Disk /dev/sdc doesn't contain a valid partition table
[root@cspdv-dlblade-13 ~]# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.


The number of cylinders for this disk is set to 32635.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Where does it say that your reboot will fail?

Well it doesn't But a am worried the whatever was not recoverable could be system stuff. The message said here was data there and I am not sure why. I dont want to try and reboot if data will be gone. how can I tell what it was talking about?

this is what concerns me
[root@cspdv-dlblade-13 ~]# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

I don't think that it will cause any boot issues or data loss.

Your /dev/sdc disk is not partioned. This is general message which I can see on unpartioned disks.

Even if there should be a partition table it should be easy to recover that using testdisk.

ah but when i do pvcreate
