Can't mount snapshot #26

Closed defder-su closed 2 years ago

defder-su commented 2 years ago

Nothing happens.

This is unfortunately working as intended. Back when I implemented it, finder never showed the mounted snapshots, even when they did show up as correctly mounted on the commandline. Clones should work.

Finder never showed the mounted snapshots

Is it accessible from CLI? I can't find (though saw such topic somewhere in www). 'zfs get mountpoint' for snapshots returns empty, and 'zfs set mountpoint' outputs 'this property can not be modified for snapshots'. Ideally, if ZetaWatch will output mountpoint path making able to copy it to use with CLI (e.g., mc) or with some alternate file manager.

Snapshots are mounted inside each dataset, in the .zfs/snapshot directory. That directory is not visible in ls, but you can cd into it. On some systems, these are auto-mounted by default. But either way, MacOS' Finder doesn't show them, so you should clone the snapshots if you want to access files via it.

cd .zfs/snapshot && open . opens mounted snapshots in Finder (macOS 10.13).

So, the app could perform cd .zfs/snapshot/<snapshot> && open . when mounted.

Hmm... It worked, but now all mounted became just empty folders. I believe it will work again after restart macOS though.

The GUI was never reliably able to look at mounted snapshots. Not even with snapdir=visible. Clone the snapshot if you want to look at snapshots in the GUI.
