After upgrading to High Sierra on an 2011 MacBook Air, when running Disk Aid on the boot disk (auto-converted to APFS) I get this error:
error: snap_metadata_val object (oid 0xe79f): invalid extentref_tree_oid (0x0)
it still says the check completed sucessfuly, but this error looks not benign. I also booted in recovery mode and get the same error.
MacBook Air (13-inch Mid 2011), macOS High Sierra (10.13)
Please post the commands and outputs.
Yay, that was it for me as well. A dataless time machine snapshot. Thanks
Can you try run all commands as super user (root). I know the document does not states that.
Prepend all those tmutil commands with sudo, e.g.
sudo
You should write this command:
sudo tmutil delete 2017-11-27-194607
Thanks a lot for your help it worked for me too 🙂
Yep. - there was a dataless snapshot on my SSD that was causing disk verification to fail exactly as described. Removing is allowed the verification to complete. This with High Sierra 10.13.4.
I have found Disk Utility in 10.13.5 checks each snapshot in a way I haven't seen before. Fixed my errors automatically. Has Disk Utility been updated?
When I try:
tmutil listlocalsnapshots /
I don't get any snapshots.
thanks you. I resolve the problem with you process.
