vxrsync finds differences after VVR sync using network

Split off from https://www-secure.symantec.com/connect/forums/vvr-block-level-backup

I have a lot of data:  2  RVG,  each RVG has 2 volumes  about 400GB for each one

the network bandwith is about 10 to 40 mb/s

when i synchronise with network it seems to be ok

but when i  check the synchro by this command:

vradmin -g DG_x -verify syncrvg myRvg Mvvr_secondary

I have the following error:

VxVM VVR vxrsync INFO V-5-52-10190 Verification of the remote volumes found differences.

even if  i  ommit tis message when i test the remote site it seems to be ok but when i lunch rman

i have the following error:

         RFN = 3, BLK = 1043, RDBA = 12583955

  • Can you give more information:

    Did you did initial sync using autosync (startrep with "-a" flag) - how long did this take?

    Was autosync using smartmove - this is turned on by default for 6.1 and only syncs used filesystem blocks (use vxtune to see if this is on or off), and so syncrvg would then show differences

    Did you then run "vradmin -verify syncrvg" and did you umount volumes before running this - if you didn't then this is another reason why it would show differences
