Problem: I want to replicate volumes larger than 16TB. Is there any possibility to avoid this limitation? Solution: There is a patch but there is a risk that the bigger the volume is the harder it may be to repair file system in case of corruption etc. Also all our tests and certifications...

Hardware failure can be a show stopper for any shop without proper backups, and hardware reserves. It can be very costly to send hard drives for data recovery. Even with a proper backup plan in place, failures can happen. To mitigate some of the headache, and expense in drive recovery, and...

Problem:  I had modified my tasks and now would like to recreate the volume replication meta-data task. How this can be accomplished? Solution: In order to recreate the Volume Replication meta-data, access the GUI in the CONFIGURATION -> Volume Manager -> Vol. Replication ->...

  Discription of Connections in relation to Replications:   Failed. Transient state following an I/O failure report by the local block device. Next state: Diskless.   Inconsistent. The data is inconsistent. This status occurs immediately upon creation of a new resource, on both...

Problem: Can you shed some light why we need to specify the bandwidth when create a volume replication task and what is the recommended value for the SyncSource bandwidth.   Solution:   The bandwidth need to be specified because the daemon works with very high priority. So, in some...

Volume replication is very similar to RAID 1. The first stage involves rebuilding the destination as a copy of the source volume.  The next stage is a continuous online modification of the destination volume to preserve the mirror copy. The difference between this process...

Yes, the file would in this situation also be deleted on the destination volume.

Example application:  There are two SANs using replication; one of them needs to be moved to a different location so that it synchronizes over the WAN, which means its IP will change.    Solution: Stop your replication task by clicking on the stop button in...

Data replication: In data replication, the destination share is available all the time - however, it should be used only for backup purposes because if you change some files, they will be replaced during the next synchronization. Volume replication: In volume replication, the volume will...

As concerns volume replication, you need to make sure that the DRBD daemon version is the same on both Open-E machines (you can check this by downloading the system logs and examining the file drbd.log). If the version is the same, it should work.
