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.

Start by doing what's necessary, then what's possible, and suddenly you are doing the impossible!!!

Subject: Delaying 64 bit aggregate upgrades

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
