By default, trace logs occupy a specific amount of kernel or server process memory; however, the size of this memory space can be changed. To change the size of a trace log, do the following:
1. Verify that you have the necessary privilege. To change the size of a kernel log, you must be logged in as root on the local machine. To change the size of a server process log, you must be listed in the administrative list associated with that process on the corresponding machine; if necessary, issue the bos lsadmin command to check.
2. Issue the dfstrace setlog command to set the state of each specified event set:
$ dfstrace setlog -log log_name -buffersize 4_kilobyte_units
[-cdsentry server_entry_in_CDS]
The -buffersize option defines the size of the log in kwords. If a specified log is already allocated, it is cleared and freed when this command is run, and a new log of the desired size is created. Otherwise, a log of the desired size is created when the log is allocated.
The following command sets the size of the ubikvote server process log on the machine named fs1 to 120 kilobytes (30 kwords):
$ dfstrace setl ubikvote 30 -cdsentry /.:/hosts/fs1/flserver
