nbd-trdump - Man Page
translate an nbd transaction log into human readable form
Synopsis
nbd-trdump
Description
nbd-trdump translates a transaction log produced by nbd-server (specifically by the transactionlog configuration directive) into human readable form.
The command acts as a traditional UNIX filter, i.e. the transaction log must be supplied on standard input, and the human readable output is sent to standard output.
Output
The following may be output:
- >
A request packet sent from the client to the server.
- <
A reply packet sent from the server to the client.
- <S
A structured reply packet sent from the server to the client.
- H
The cookie of the packet. Note: previous versions of this man page (and the NBD spec) referred to the cookie as the "handle".
- C
The command sent.
- O
The offet from the start of the disk.
- L
The length of data.
- E
The error returned.
- T
The type of the structured reply message.
