Subject: [CORRUPTION FILESYSTEM] Corrupted and unrecoverable file system during the snapshot receive
Date: Mon, 21 Nov 2016 13:09:15 +0100	[thread overview]
Message-ID: <1479730155.5832e3eb3fde8@webmail.adria.it> (raw)

Hi.

My system: Fedora 23, kernel-4.7.10-100.fc23.x86_64 btrfs-progs-4.4.1-1.fc23.x86_64

Testing the remote differential receive (via ssh and in local network) of 24
sequential snapshots, and simultaneously deleting the snapshot, (in the same
file system, but in a different subvolume), there has been an file access error,
and the file system has corrupt.

Both scrub, both recovery and clear_cache mount options, both btrfsck, have
failed, the file system is left in a state unusable.

After reformatting the filesystem, remote receive of 24 snapshots worked properly.

The file system is used exclusively for receive the snapshot, it is composed of
a single device.
The initial snapshot is a linux installation of 50Gb.


I think that there was a race condition between the receive and deletion of
snapshots (that were performed on two different subvolume).


Best regards.
