I/O Errors During Resynchronization
Snapshot resynchronization (started by vxsnapsyncstart, or by specifying sync=on to vxsnap)
stops if an I/O error occurs, and displays the following message on the system console:
VxVM vxsnap ERROR V-5-1-6840 Synchronization of the volume volume
stopped due to I/O error
After correcting the source of the error, use the following command to restart the
resynchronization operation:
# vxsnap [-b] [-g diskgroup] syncstart volume
See the VERITAS Volume Manager Administrator’s Guide and the vxsnap(1M) manual page
for full details of how to use the vxsnapsyncstart command.
