Checking whether FastResync is enabled on a volume
To check whether FastResync is enabled on a volume, use the following command:
# vxprint [-g diskgroup] -F%fastresync volume
If FastResync is enabled, the command returns on; otherwise, it returns off.
If FastResync is enabled, to check whether it is Non-Persistent or Persistent
FastResync, use the following command:
# vxprint [-g diskgroup] -F%hasdcolog volume
If Persistent FastResync is enabled, the command returns on; otherwise, it returns
off.
To list all volumes on which Non-Persistent FastResync is enabled, use the
following command.
Note: The ! character is a special character in some shells. The following example
shows how to escape it in a bash shell.
# vxprint [-g diskgroup] -F "%name" \
-e "v_fastresync=on && \!v_hasdcolog"
To list all volumes on which Persistent FastResync is enabled, use the following
command:
# vxprint [-g diskgroup] -F "%name" -e "v_fastresync=on \
&& v_hasdcolog"
Disabling FastResync
Use the vxvol command to turn off Persistent or Non-Persistent FastResync for
an existing volume, as follows:
# vxvol [-g diskgroup] set fastresync=off volume
Turning off FastResync releases all tracking maps for the specified volume. All
subsequent reattaches do not use the FastResync facility, but perform a full
resynchronization of the volume. The full resynchronization occurs even if you
turn on FastResync later.
