Last time I tried UFS2 snapshots I found out two serious limitations.
The first is it doesn't work when UFS Journaling is used. The second is
that taking a snapshop on a large filesystem can cause parts of the
system to freeze for many minutes up to hours when accessing files
part of the snapshot, depending on the size of the filesystem.
That's why I could not use it on my server with > 1TB UFS2.
Did this improve in the last year? (I guess my experience is from the
time around 9.0 release).
