[linux-lvm] 8TB logical volumes with LVM2

[linux-lvm] 8TB logical volumes with LVM2

[Devon H. O'Dell]

Hello folks,

I'm trying to configure a system with 2 12 port 3ware 9550SX SATA RAID
cards to join the two physical volumes exported by the cards into a
single logical volume. There are 24x400GB drives, so the total is just
above 8TB.

After running the following commands:

pvcreate --metadatasize 1024 /dev/sdb1
pvcreate --metadatasize 1024 /dev/sdc1
vgcreate -s 128M vg0 /dev/sdb1 /dev/sdc1
lvcreate -n lv0 -L8T vg0

The lvcreate command gobbles up CPU and memory as would be expected,
however, I get the following error message:

device-mapper device too small for target: /dev/sdb1
device mapper ioctl cmd 9 failed: Invalid argument.
could not load device vg0-lv0
failed to activate new LV

Am I doing something incorrectly? I've tried with both Fedora Core 3
and Fedora Core 4. Any pointers on how I should continue with this
would be greatly appreciated.

Kind regards,

Devon H. O'Dell

I did pretty much the same thing on a Caos Linux system with two
twelve-port 3ware 9000 SATA raid and twenty-four 250 GB disks,
creating one big 6.6T file system.  No problems to report from
here.  You did make GPT labels on the two SCSI devices, didn't
you?

Apparently not. I've got it now; I did indeed need to create the GPT
labels. Thanks for the reminder; I appreciate it.
