will a corrupted data/filesystem on primary will also get copied to
secondary (garbage in, garbage out?) on drbd 8.3?
if yes, how to prevent this?

Hello Umarzuki,
I don't know for sure, but in one instance it felt like it.
Cheers, Peter.

IIRC all garbage you write to DRBD gets synchronised. Data getting
corrupted at the hardware-Level (e.g. Defective Raid controller) only gets
synced if you trigger a resync after you did a online verify and found out
the data differs.
DRBD has no way of knowing what goes on on the hardware
Hi,
i'm hitting a bug in drbd, with latest CentOs and drbd 8.3.12 using GFS2
on top with cman and rgmanager.
Here is the simplest method to have it occur.
1. Start drbd on node s2
2. Start drbd on node s3
They sync up:
[root@s3 ~]# cat /proc/drbd
version: 8.3.12 (api:88/proto:86-96)
GIT-hash:
Prevent? Good applications.
Recover? Good backups.

Hi,
I'm in the middle of switching from a software RAID1 based on MD to another one
based on DRBD but using the same disks.
I've verified that no data loss occurs during this operation, but I'm wondering
if it's possible to avoid the initial full synchronization between disks since

If it's file system level, yes. However DRBD can detect low-level IO
errors and act accordingly.
Hi all,
thank you. It has seemed to me that the solution is to clear the bitmap and let
DRBD consider data consistent on both disks.
Indeed I followed the steps showed in
http://www.drbd.org/users-guide-8.3/re-drbdsetup.html and it works fine!
After I've disabled MD raid and configured DRBD
Guys,
I'm trying to better understand the unplug-watermark parameter settings, and
honestly I don't find much info about a rational way to do it. I understand
that it strongly relies on the general specs of the storage subsystem in
use, but except that. I've seen a discussion about the CCISS

You can also pay him. Then you can have his number on speed dial so he
reads the links (and their contents) to you:-)
Have fun,
