Users of HD6500 can now create a Btrfs volume of up to 1 PB. This update automatically converts existing volumes that use the Btrfs (Peta Volume) file system to Btrfs. However, to create a volume larger than 200 TB, a RAID 6 storage pool and at least 64 GB of system memory are still required. Fixed an issue where tasks scheduled at a high frequency generated a lot of logs and occupied system partitions.
