Hi there..
I hope this is the correct mailing list to ask this question.
I have a Dell Poweredge R710 server (brand new)... 7.2-RELEASE installs fine
but I'm having a problem getting any large partitions over approximately
500GB. During the installation it allows me to create 4.5TB partition but
after rebooting it's only really 500GB +/-
Has anyone successfully installed into a disk this large? This is a RAID5
array using the Dell Perc 6/I controller
I have installed now 6+ times with smaller partitions (100GB even) and run
into problems . hoping someone could share how they got large disk support
working.. I'd be happy with several 1TB partitions but when I configure it
this way and exceed 4 partitions it tells me disk error creating
partitions..
Unfortunately, MBR and BSD disklabel use 32 bit values, so they are
limited to 2TB. GPT uses 64 bit values, but I don't believe that
FreeBSD fully supports it. You can see the Big Disk project page [1]
for more information.
As a workaround, you may wish redo your RAID configuration so that you
have multiple logical volumes (e.g. 2T, 2T, 0.5T).
