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 started growing the volume a coupe hours ago to keep it under 70% full.
What is going on?

thanks
