According to this KB:https://kb.netapp.com/app/answers/answer_view/a_id/1000287
In the output of sis status -l for the same volume, the following line is included:
Logical Data: 3509 GB/49 TB (7%)
Logical 4K records are = 919863296
Total checked 4K records are = 18115836411
Hence, Filer is consuming total 4KB blocks = 18115836411 - 919863296 = 17195973115 (4K records)
Total size in TB = 17195973115 / 1024 / 1024 / 1024 = 16TB
Does that mean = out of 49 TB, 16Tb is been consumed by stale-fingerprints, and if consider 20% of total logical data i.e = 20 % 3509GB = 701GB = 0.7 TB
Total space that can be recovered = 16 - 0.7 = 15.3Tb can be recovered
Is that correct calculation ?
See The Solution
I think I foud the clue in the same document:
Size of each record = 32 bytes
= 17195973115 x 32 = 550271139680 bytes
= 55027113968 / 1024 / 1024 / 1024 = 512GB NOT 16TB
