at the moment of a call is somewhat obvious (and, probably, doesn't say what you wanted to). How about to get rid of it?

// List must return list of all the containers in the FrostFS network

I am not sure Is will work now as expected (compared to As), do we use Is anywhere for status errors?

@fyrchik
I am not sure that this can be incorrectly ignored (the container cannot be appended to removed list and thus sync will try to sync the container?). Anyway, the netmap cannot be updated until we cannot get info about the container

How is netmap update connected to all this?
It is right, not to remove container in case "unknown" error happens.

Sorry, nevermind

newMap, cnrsToSync := s.containersToSync(cnrs)

s.syncContainers(ctx, cnrsToSync)

s.removeContainers(ctx, newMap)

I have mistaken newMap for netmap :)
