Hi,

I am new to LVM.
I want t o create LVM volume group.
So first I created a partition and then runned "pvcreate" root@localhost ~# pvcreate /dev/hda5
Device /dev/hda5 not found.

But that is present.I didn't get why it is showing "Device not found" Can anyone help me.It is urgent for me.

Can I create volume group on EVMS volumes?

Thanks,
susmitha

sometimes you have to reboot for partition changes to take effect.
what does this show: fdisk -l

Hi,

"fdisk -l " is showing correctly I mean showing those partitions. But I didn't get why it came. Ok I will try by rebooting.

Thanks for immediate reply :)

If the partitin table went into effect, you probably just needed a vgscan to pick up the new partitions. Rebooting works too though. ;)

Hi,

After rebooting now its working.
But I am using EVMS for creating partitions.
so if I am using "pvcreate /dev/evms/hda5" same error is coming but if I use "pvcreate /dev/hda5" it is working after reboot.

I had doubt whether I can use EVMS volumes for LVM tools. But it is not working.Is there any way to work on EVMS volumes?

I am creating RAID1 using EVMS and I want to create LVM on that RAID1.But in EVMS, LVM on RAID1 had some problem.So I thought to use LVM tools for that situation means LVM on RAID1.

How to proceed in this situation?

Thanks for help
