Andre,
I guess I need a different refresher. I seem to recall people doing upgrades and their systems being slow for an extended period of time immediately afterwards. I thought it was doing the 64 bit upgrade. Since that isn't the case, I need to try and figure out what was affecting the systems. I'll try a broader search of the mailing list and see what I can find.
Thanks,
Jeff

Jeff,****
32 to 64bit conversion doesn’t happen that way. The ways you’ll get a 32bit aggregate to go to a 64bit aggregate are:****
**a. **After upgrading to 8.1, adding additional spindles to the 32bit aggregate to go beyond the 16TB limit and, in the background, the 64bit conversion will start.****
**b. **A SnapMirror from a 32bit to 64bit aggregate and when the mirror relationship is broken, the 64bit conversion will start.****
If you are just doing an in-place upgrade to 8.1.2, the aggregate conversion process will not start.****

Greetings,
Is there a way to go from 7.3.5 to 8.1.2 without having all the aggregates start doing automatic conversions to 64 bit?
Our current filers are getting hit pretty hard. I think the OS upgrade will help, but I'm afraid the aggregate upgrades will generate too much disk activity and slow things down for a day or two. We have ~9 aggregates per head that are 10T or larger. Most of these only have one volume in them. The shared ones have a few volumes with 40M+ inodes in use. If I can upgrade the aggregates selectively it will make it less noticeable to the users.
Thanks,
Jeff
