switchlog - moves an AdvFS file domain transaction log
/sbin/advfs/switchlog domain_name vol_id
Specifies the name of an existing file domain.
Specifies the number of the new volume to use for the log.
The switchlog command relocates the transaction log of the specified file domain to a different volume in the same file domain. Moving the transaction log within a multi-volume file domain is typically done to place the log on either a faster, less congested, or mirrored volume.
Use the
showfdmn(8)
command to determine the current location of the transaction
log. In the
showfdmn
command display, the letter
L
displays next to the volume that contains the log. The
showfdmn
command also displays all of the volumes and their volume
numbers.
You must have root-user privilege to execute this command.
In order create a multivolume file domain, you must purchase and install
the POLYCENTER Advanced File System Utilities layered product.
The following example displays the log's current location by using the
showfdmn
command and then moves it to volume 2 by using the
switchlog
command.
