xfs_growfs doesn't grow on 2TB raid

[jack the ripper]

2TB is indeed the limit for MBR partitions but I thought this had nothing to do with a "virtual" software raid? The disks an sich have indeed an MBR partition table, but each disk is only 500GB.

Can you confirm that I need GPT for my software raid?

Sorry for top-posting, only have Outlook on my notebook.

 

Isn’t 2TB the normal partition size limit? So if you want
>2TB partitions, you must use GPT partitioning, “parted” can create such
partitions but not fdisk. AFAIK there is no option to simply change a disk from
normal partitions to GPT without backup/repartition/restore.
