VDR checksum errors

Hello,

From time to time I see messages in the VDR message log like this:

Oct  1 11:49:10 vmdr-a datarecovery: Chunkdedupe WARNING: Slab file 354: Header 1 at header offset 34604544 is invalid (checksum error - possibly result of purging).
Oct  1 11:49:13 vmdr-a datarecovery: Chunkdedupe WARNING: Slab file 275: Header 1 at header offset 34604544 is invalid (checksum error - possibly result of purging).
Oct  1 11:49:15 vmdr-a datarecovery: Chunkdedupe WARNING: Slab file 251: Header 1 at header offset 34604544 is invalid (checksum error - possibly result of purging).

Is this anything to worry about, or just part of VDR's day to day operations?

Thanks

Nick

Hi,

Thanks for the suggestion. What exactly does that do? I don't really want to try things on th production system without knowing the impact!

Thanks

Hi,

I'm also seeing tons of this message, with the exact same value for 34604544, in my /var/log/syslog, during a restore of a VM.

However the restore seems to have succeeded.

Any explanation for this ?
