[OpenAFS] shadow volumes and 'vos syncvldb'

[Arne Wiebalck]

Dear all,

If detecting shadow volumes, does 'vos syncvldb' really update VLDB entries=
=20
to point to the shadow location instead of the location of the R/W source v=
olume=20
as stated in the man page? (Some simple tests and a quick check in the code=
=20
seem to indicate that at least in 1.4 this is not the case).

Would I need to run 'vos delentry' on all volumes before running 'vos syncv=
ldb'=20
on the shadow server or is there something else I should do?

I assume that in a disaster recovery situation where the source server is n=
ot=20
reachable I probably need to delete the entries anyway as=20
- 'vos syncvldb' will need a macroscopic timeout for each volume on the=20
  unreachable server, and
- it will not even update VLDB in the end if communication fails. Correct?

TIA,
 Arne
