I would agree!! I upgraded to 8.1.3p2 on several arrays over the past month and there hasn't been any fall out.

I'd recommend 813p2 immediately...

Yah, just found it while googling I guess, must be bug id #657692 :-/****
Anyhow, I’m now stuck with this:****
sis status****
Path State Status Progress****
/vol/CIFS_SHARES Enabled Active Fingerprint is being recovered from aggregate (6% complete)****
It’s doing that since quite some time now, although it now actually jumped from 0% to 6%, so it at least is still alive.****
This bug is first fixed in 8.1.2P4 as it seems, so I might need to upgrade ASAP; for now, I’ll check if it at least finishes this process now, my volume is filling up quickly, but there’s still some aggregate space left so I’ll just increase the volume size before it goes full.****
I’ll go above the magic 80% fill of an aggregate then, but better that then having the volume go full.****
I’ll see how it goes and if it troubles me too much, I hope there is a way to abort sis in that state.****

Isn't that the Dedupe bug again, that was fixed in 8.1.3? (since like 8.1.2P3 or P4)...
There was a thread about it some time ago...
Anyway, I'm off to bed, just wanted to point you in the right direction.

I’m aware that deduplication _*SHOULD*_ be a background process hugging up as much resources as it can but when host i/o is needed, it will be preferred over deduplication.****
There are no other tasks running at the same time (snapvault, etc.), and the virtual machinse on this system are _*VERY*_ slow – f.ex. logging in via RDP on one of the virtual machines now took > 1 minute for the login window to appear.****
This is a FAS2240 with 24x600 SAS 10k and basically my question now is: Is there any way to tell a-sis to really run with lower priority or is this a bug in the OnTap version I’m running? I’ve used a-sis a lot in the past and never had performance issues like this when it was running…****
I’m thankful for any ideas how to track down this issue or improve performance while a-sis is running.****
Thanks,****
