SAN/LVM question
Hey everyone.
I am working on designing a logging solution for a deployment we have going out in a few months. Right now we have a single storage head end, connected via fibre to a SAN. Basically the plan is to create a number of smaller LUNs on the SAN, and then use LVM2 to handle concatenating them all together like a single disk.

The largest volume we expect to see is about 130 TB. So with that in mind, is there any reason I would use GPT vs MBR?

Also, I plan to use XFS as the filesystem due to the possible sizes of some of the volumes (ext3 caps out at ~24TB now?). Is there any known issue with resizing XFS filesystems on top of LVM2? I haven't been able to find much when searching for both of them.

Any help or advice would be appreciated. Thanks!

fp

fp(7d)                                                                Devices                                                               fp(7d)

NAME

       fp - Sun Fibre Channel port driver

DESCRIPTION

       The  fp  driver  is a Sun fibre channel nexus driver that enables fibre channel topology discovery, device discovery, fibre channel adapter
       port management and other capabilities through well-defined fibre channel adapter driver interfaces.

       The fp driver requires the presence of a fabric name server in fabric and public loop topologies to discover fibre channel devices. In pri-
       vate  loop  topologies,  the  driver discovers devices by performing PLOGI to all valid AL_PAs, provided that devices do not participate in
       LIRP and LILP stages of loop initialization.

CONFIGURATION

       The fp driver is configured by defining  properties in the fp.conf file. The fp driver supports the following properties:

   mpxio-disable
       Solaris I/O multipathing is enabled or disabled on fibre channel devices with the  mpxio-disable  property.  Specifying  mpxio-disable="no"
       activates I/O multipathing, while mpxio-disable="yes" disables the feature.

       Solaris  I/O  multipathing  may be enabled or disabled on a per port basis. Per port settings override the global setting for the specified
       ports. The following example shows how to disable multipathing on port 0 whose parent is /pci@8,600000/SUNW,qlc@4:

       name="fp"    parent="/pci@8,600000/SUNW,qlc@4"    port=0
       mpxio-disable="yes";

   manual_configuration_only
       Automatic configuration of SCSI devices in the fabric is enabled by default and thus allows all devices discovered in the SAN zone  to   be
       enumerated   in  the  kernel's  device tree automatically. The manual_configuration_only property may be configured  to disable the default
       behavior and force the manual configuration of the devices in the SAN. Specifying manual_configuration_only=1 disables the  automatic  con-
       figuration of devices.
