I have a backup disk with one ZFS pool and a number of filesystems that should receive incremental snapshots.
For some but not all filesystems it refuses with "cannot receive incremental stream: destination ... has been modified". I am sure that I did no such modification, this is purely a backup disk that has never been used to do any work on it. Did this happen to anybody else? What's behind this? Please tell me it is not something silly such as atime having been changed by a find(1) job?
Anyway, assuming this can't be fixed, my only alternative is to send a non-incremental snapshot, which requires to remove the entire target subsystem. Apart from being slow this also has the disadvantage of losing all previously existing snapshots in the backup disk.
Any ideas what the best way to deal with this is?
