In a SnapVault relationship, does large size need to be enabled on both source and destination? I have a source flexvol that's 100TB and has snapvaults. Obviously, this can hit the 100TB max on the destination with snapshots, so I tried to enable large size on just the destination:
Error: command failed: Modification of the following fields: is-large-size-enabled not allowed for volumes of the type "Flexible volume - DP read-only volume".

Why, oh why, would you prevent this where I need it the most? If I enable large size on the source, does this carry over to the destination?

probably will work if you break the relationship, set it on both sides, and resync... but, as usual, YMMV... and I haven't tested it

#

It's not necessary to break or resync, just make the change on the source and update the relationship. This is one of the volume settings that SM will replicate.
