Hi,
BTW, you can create a soft link on the filer called QTREE1 pointing to /vol/vol1/QTREE1 and mount using the link name.
Cool! I didn't know the NetApp could internally resolve symlinks for NFS/CIFS exports/shares and still give us the "right stuff" from rquotad and what not.
Also regarding ndmpcopy, I've used it many times without any problems and also for moving qtrees or even lower lever directories.
We've used ndmpcopy *extensively*. We've also modified the source to fix some frustrating UI "features". While it works nicely in most instances, last time we tried to do incremental ndmpcopy's to facilitate data migration (like successive rsync's), it hosed a bunch of data on the destination. What's more is that there wasn't any indication in its output that anything went wrong, so we cut-over about 300GB of mission critical data that had an undetermined number of problems throughout it. So all 300GB was suspected of being corrupt.
After the arduous weekend we spent initialy copying this data, we got the opportunity to spend the next weekend re-do'ing the whole effort from tape. Lucky us, huh? =)
I'd like to see a "-i" option in ndmpcopy like there is in jndmpcopy that allows an infinite number of incremental restores. Additionally I'd like ndmpcopy to be a documented and bundled tool with new filers, rather than a "supported tool". This would raise our confidence in it, and to be honest, migrating data is one of the things that NetApp doesn't provide much of an easy solution for. Maybe a robust version of the CLI java jndmpcopy that runs on UNIX and NT with another java program that acts as a GUI front end. That would satisfy both the UNIX and NT folks and be as platform in-specific. Something like the Veritas Storage Administrator...
