Marcus,

WAFL "steals" 10%; this loss is inherent in the file system design.

Think about how you lose up to 12% of your free space for the MFT on an NTFS volume; same thing on WAFL except it isn't allocated as a contiguous chunk like the MFT - rather the space is used dynamically to allow the filesystem to function properly.

regards,

Alan.

Subject: volume disk space

I created a volume on F880c, ONTAP 6.4.1, with CIFS as follows:

37 - 72GB disk

Raid group size = 14 with 3 Raid groups

No snapshot

snapshot reserve = 0

But in Filerview the volume space shows 1.98TB and 'df -g' shows 2031GB. I thought the volume space should be 2.257TB (34 data disks x 66.385GB). Map to the volume from a Windows client and it shows 1.98TB. Why am I missing a lot of disk space?

cheers,

Marcus Bui
