Vertica and LVM

[scottbossi]

Now that HP isn't going to support Vertica on LVM, I'm curious what people are using?  For me, this is a big deal...

Hi Scott,

 

Here is Vertica statement regarding filesystem options:

 

Filesystem Options

• HP Vertica supports the ext3 and ext4 file systems.
• Linux Logical Volume Manager (LVM) is not supported.
• The recommended disk block size is 4096 bytes.

Hi there,

 

Does someone got an official response from CA regarding the LVM support for IM 2.0 ?

 

We are already running several installations on RHEL6 with LVM enabled.

 

Greetings,

Ben

Hi all.

 

The official statement from CA about this is in the CA Infrastructure Management Data Aggregator Readme Release 2.3.3:

 

6.4 Linux Logical Volume Manager (LVM) is Not Supported

Vertica does not support Linux Logical Volume Manager (LVM) on any drive where catalog and data database files are stored.

 

Thanks,

Giuseppe

Thanks for sharing Guiseppe. I actually opened a ticket because I didn't find it in the documentation. The trick is to also read the HTML readme, not just the PDF version

My company already uses ext3/4 filesystems - the issue is that they are created and managed by LVM.   If people aren't using LVM to create the filesystems, what are they using?

Maybe plain block devices /dev/sda1, /dev/sda2 etc,

So the good news is that as of HP Vertica v9, logical volumes are again supported.  Vertica v9 is included with the newest versions of CAPM, but the documentation and support for logical volumes hasn't been updated.
