Hi,

#lvcreate -L 2000000 /dev/lvolX

man lvcreate says:
-L lv_size

Allocate space to the logical volume, specified in megabytes. lv_size is a decimal value in the range 1 to 16777216 (the implementation limit).

As a good practice, I never create filesystems bigger than 500GB, sometimes due to vendor requirements, I go up to 1TB. The reason I don't recommend larger than 1TB filesystem because of the pain of doing fsck in case filesystem corrupted or even restoring when you lose that filesystem for any reason. I think it's more manageble if the filesystem is under 1TB. But it's all up to you to decide what suites for you.

Good luck

Is it possible?

That depends on what release we're dealing with. Assuming we are dealing with 11.0 or more recent, the following applies:

lvcreate -L 2000000 -n logical volume name then volume group.

for example if u want to create a logical volume lvol9 with the size 2000000 Mb under the volume group /dev/vgora1

then u have to use the command

lvcreate -L 2000000 -n lvol9 /dev/vgora1
