In fact the thing that seems strange to me is that when I create a snapshot, immediately it is mounted: it is not a real problem, it is only a strange behaviour. The "standard" behaviour is to create the file-system and then mount it: two separate actions. GB is correct: Tru64's ADVfs snapshots, which were (are?) essentially the same as btrfs snapshots, were (are?) not mounted on creation http://www.tru64unix.compaq.com/docs/base_doc/DOCUMENTATION/V51B_HTML/MAN/MAN4/0124____.HTM indicates that these things were (are?) called "clones" and http://www.tru64unix.compaq.com/docs/base_doc/DOCUMENTATION/V51B_HTML/MAN/MAN8/0048____.HTM Here's the example code for creating and mounting a clone with tru64 ADVfs, from clonefset(8): The following example creates a read-only copy of the credit_fs fileset that resides in the accounts_dmn domain. The clone fileset name in this example is credit_clone1. This example also performs an online backup and removes the clone fileset after the backup is complete: # mkdir /mnt/credit_clone1 # clonefset accounts_dmn credit_fs credit_clone1 # mount -t advfs account_dmn#credit_clone1 /mnt/credit_clone1 # vdump /mnt/credit_clone1 # umount /mnt/credit_clone1 # rmfset account_dmn credit_clone1 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
