i am currently trying to find a solution to synchronize two storage servers both running open-e dss 6.

  • i need only one-way synchronization (storage A -> storage B)
  • my volume is 30TB in size, therefore dss' replication will not work (at least afaik it only supports volumes up to 16TB)
  • there are about 1.000.000 files to synchronize

i've tried with rsync but things got very, very slow with a million files.

i have no clue if there are any better solutions for this problem, so any help would be very much appreciated!

What version of rsync did you use and how much memory did it have? – Chopper3 Nov 24 '10 at 16:10

You could potentially use something like DRBD to handle the replication.

yeah, open-e even supports DRBD -- the problem is, that it seems to be limited to volumes up to 16TB. at least with open-e. or is this a general limitation of DRBD? – harald Nov 24 '10 at 21:50
