Chapter 4, Logging Commands and Transactions

Logging Transactions

The vxtranslog command allows you to log VxVM transactions to a file. The following

table demonstrates the usage of vxtranslog:

Transactions are logged to the file, translog, in the directory /etc/vx/log. This path

name is a symbolic link to a directory whose location depends on the operating system. If

required, you can redefine the directory which is linked. If you want to preserve the

settings of the vxtranslog utility, you must also copy the settings file, .translog, to

the new directory.

Note The .translog file is a binary and should not be edited.

The size of the transaction log is checked after an entry has been written so the actual size

may be slightly larger than that specified. When the log reaches a maximum size, the

current transaction log file, translog, is renamed as the next available historic log file,

translog.number, where number is an integer from 1 up to the maximum number of

historic log files that is currently defined, and a new current log file is created.

A limited number of historic log files is preserved to avoid filling up the file system. If the

maximum number of historic log files has been reached, the oldest historic log file is

removed, and the current log file is renamed as that file.
