Hello,
Documentation states that VM Panorama mode can support up to 24TB of log storage on a single virtual appliance.
Each logging disk has 2TB of storage capacity for a total maximum of 24TB on a single virtual appliance
So we add 12 virtual disks with 2TB of storage to the machine.
> show system disk details shows 12 disks with 2097152 MB of storage. Good.
> show system disk-partition is where things get confusing. PAN-OS creates 1.7TB partitions for each disk no matter what:
Disk /dev/sdb: 2199.0 GB, 2199023255552 bytes, 4294967296 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: gpt
# Start End Size Type Name
1 19531 3706898437 1.7T Microsoft basic primary
Disk /dev/sdc: 2199.0 GB, 2199023255552 bytes, 4294967296 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: gpt
What exactly is going on here? Why only a range of 9531 - 3706898437 sectors being used? Which effectively limits disk size to roughly 1.7TB.
So now we are left with 20,4TB of total storage, in theory (12 x 1.7).
However, when we create a Collector Group and select all 12 disks - it only shows Max: 18.38 TB of storage!
Can someone please explain what happens to the rest, almost 6TB of storage?
Thank you.
