I ended up expanding the extended partition to encompass the remainder of the disk. I then created 2 ext4 partitions, a 6 gig for private data that can be mounted for use then unmounted and the remainder as a big data drive. Both are dmraid mirrored partitions. The current mount options are: /dev/mapper/nvidia_ecaejfdip12 /data ext4 defaults 0 1 /dev/mapper/nvidia_ecaejfdip11 /home/david/pvt ext4 defaults 0 1 are you guys saying I should add 'auto_da_alloc' as an option for all ext4 partitions? -- David C.
