Hi, Would you like to show the "btrfs send/receive" command the script are using, including all the parameters, and how the script waits for a completion of a transfer. >From the beginning of the thread, it seems the transfer tests are going through different network environment.

Is through to the btrfs-tools error message that the script has printed, that I realized the filesystem corruption. P.S. Various messages that you see in the working examples of the script, are emitted directly by the btrfs-tools.
