Hi,

I have a clone volume that contains an aborted saveset called /tmp. I
would like to re-clone the original /tmp back to this same clone volume,
but NetWorker will not do it. Instead, it wants to clone /tmp to a new
clone volume. This does make some sense since I know saveset ids are
unique per volume, and cloned savesets share the same saveset id as the
originals; however, I know that cloned savesets also have a clone id,
allowing them to be identified apart from their other copies. I know
this can be used when cloning if you want to specify which copy of the
saveset to clone, e.g. 'nsrclone -b clone_pool -S ssid/cloneid'.

Also, I know that I can list out the index info as: 'mminfo -av -S
original_volume' wherein it shows all the clones for each of the
savesets, listing each clone id. Therefore, is there not some way I can
remove the index entry for the cloned saveset, but somehow keep the
original, and then re-clone the original saveset back to the same clone
volume? I'm thinking that since it was aborted, NetWorker might allow
this? I read the man page for nsrim, but I can't see where it allows you
to specify that you want to delete the clone id entry and not the
original. Obviously, though, if you remove the clone volume, that
removes the entry -- never mind the fact that all the rest of the cloned
savesets are likewise wiped out -- so it would seem that there should be
a way to do it without removing the volume. Maybe I can somehow mark
that cloned saveset 'recyclable' and then remove it?

If not then what happens if you get 99% of the way through cloning a
volume and then one of the savesets gets aborted? Do you have to
re-label the clone volume and start all over if you're not willing to
re-clone the one aborted saveset to another clone volume that doesn't
yet have that saveset id?

Thanks.
