The original case raw size was 9.001TB(9,001,000,000,000 bytes), but the (ext3?) formatted size reported by lustre_config was 8584023MB, which is less than 8TiB. However, we have tried another case with a raw size of 11.0 TB, for which the formatted size is well above 8TiB:
root> lfs df -h UUID bytes Used Available Use% Mounted on testfs-MDT0000_UUID 717.7G 472.6M 676.2G 0% /testfs[MDT:0] testfs-OST0000_UUID 9.8T 436.5M 9.3T 0% /testfs[OST:0] filesystem summary: 9.8T 436.5M 9.3T 0% /testfs So is it the case that > 8TiB is possible to create without errors, but remains unsupported?
