So we migrated this vfiler to a 8.1.2 head in another datacenter yesterday

na01> sis status             
Path                           State      Status     Progress
/vol/vm64                Enabled    Active     Fingerprint is being recovered from volume (0% complete)

na01> df -sh
Filesystem                used      saved       %saved
/vol/vm64net2/          3829GB     3051GB          44%

Disk space is sawtoothing since the dedup job kicked off:


I've almost doubled the volume size.
Experienced this with a smaller (700g) volume as well
What is going on? Is there a way to avoid this ?

thanks
