What demon is creating the shares if using web admin ui
Hi, I have ReadyNAS 6.5.1. If I go to the WEB Admin UI, And create a new share, what demon is running on the machine and actually creates the directory and configure the share (for example NFS/SMB s...
You created a directory; the ReadyNAS software created subvolumes (which can have snapshots, quotas, etc).
BTRFS subvolumes always have inode 256, that's the way the file system identifies that they are subvolumes.
Thanks for reply.
I understand that ReadyNASOS give the same inode to each subvolume.
Since the filesystem partition is shared for all subvolumes, it means that behind the scenes there are different inodes for these directories.
how can I in kernel space retreive the real inode of these subvolume ? or in usermode ?
You are perhaps assuming that btrfs inodes are all unique indices like they are in ext. That's not the case.
That of course does lead to the question on how you identify and retrieve the right inode structure for a given btrfs object. That's an area I haven't explored, so I don't know.
Some apps create shares. You could look at how apps do it.
