From what I can see from the audit logs they ran "ndmpcopy
/vol/old_vol0 /vol/vol0" after they had renamed the original vol0 to old_vol0.
I checked the audit logs on the test system and they did the ndmpcopy from vol0 to new_vol0, then did the rename. Would running the ndmpcopy when the original vol0 had been renamed first affect any of the files or the copy somehow? I wouldn't expect so, but I'll have him try it again in the morning.

Did they also rename "new vol0" to vol0 before running ndmpcopy? Because if path refers to non-existing volume, ndmpcopy will happily copy into the same path inside "/" - i.e. under /vol/root_volume. I just fall in that trap yesterday.
I.e. "ndmpcopy /vol/vol0 /vol/no-such-vol" will actually create /vol/vol0/vol/no-such-vol instead of complaining.

Andrey,
The new volume had been renamed to vol0 prior to the ndmpcopy. We verified the data was in the new volume and ran "ll -R" on both etc directories and diffed the files. Everything was the same.

Well ... any reason to use 8.0.1 in the first place? Actual is 8.0.2P4. I moved root volume yesterday from 32 to 64 bit using ndmpcopy without issues. The only difference was that I use it per subdirectory (I made an error initially as mentioned and could not delete extra directory as filer had no CIFS or NFS licenses; so I wanted to avoid carrying over extra garbage).

I'm traditionally in the "if it's not broke, don't fix it" category. Being an early adopter has not generally worked well for us in the past. The 8.0.1 release level works fine for most things we want it to do, except not converting the root volume apparently :-)
I'm only testing the 8.1 release because I have a NearStore that started life as a 7.2.3 system and it has a bunch of 32 bit aggregates I would like to convert and consolidate. There is no other feature that would drive me to try it out.

If you are trying to copy the root volume you need to use the following syntax:

Hmm ... yesterday I did
ndmpcopy /vol/vol0/ha /vol/new_vol0/ha ndmpcopy /vol/vol0/etc /vol/new_vol0/etc ndmpcopy /vol/vol0/home /vol/new_vol0/home
as far as I can tell it did boot just fine off the new_vol0. It was under 8.0.2P4.
IIRC option -f is needed if want to overwrite existing /etc; if there is no /etc on destination, it is not required.

If you are trying to copy the root volume you need to use the following syntax:
ndmpcopy -f /vol/old_vol0 /vol/vol0
That is the only way you can capture the system files with ndmpcopy.

Andre,
The "-f" option was not used on either the 8.0.1 system or the 8.1 test system. As Andrey pointed out, the "-f" is only needed if you are overwriting /etc on a root volume. In this case the ndmpcopy was done on a newly created volume that had no data in it prior to the copy so the -f was not required.
I may have them try it anyway just in case.
Thanks,
Jeff
