Ubuntu 16.04 DRBD Pacemaker HA Cluster 

Absolutely the BEST tutorial I have found on DRDB. Great work!

This is what I'm looking for a quite long time. Especially with "crm configure" section starting from18:16. Thank you and appreciate you for this video. This is really helpful to achieve carbonio zextras email server with DRBD HA Cluster

Hey great video. One note: in corosync configuration, since you are using udp unicast option (udpu) I think you can further simplify your configuration file and remove redundant options 'mcastport' and 'broadcast'.

Extremely informative video, very well explained and probably the best tutorial out there for DRBD. You saved my ass big time!!

Thank you, sir for the how to. Saved my bacon and was really what my boss wanted!

Outstanding video. Thank you!

Great tutorial....I should start using it ASAP.

you just made my day.. thank you sir. very much

Y donde podemos ver el corosync.conf entero, que la parte que se muestra en el video es parcial

Thank you sir! you nailed it.

When I use the primitive fs_res ocf: heartbeat:Filesystem params ....till end command. It gives me this error: ocf:heartbeat:Filesystem got no meta data does this RA exist? Help is much appreciated

thank you for this video.. so help full I have question. currently I have 3 server . can I setup DRBD on this 3 server without using DRBD manager ?

Thank you, Great Video It is working for me perfectly Can you please share any blog link if we want to attach this HA NFS cluster using bindnetaddr to Web Servers Facing issue to use this bindnetaddr

@16:10 you seem to auto correct a misspelled command ("ssyet") with a key combo? And turning it into "systemctl". What did you use for that?

hi i need help you when i add the resource DRBD, the exit is: Error: Unable to create resource 'ocf:linbit:drbd', it is not installed on this system (use --force to override)

what should i set in crm configure if i want an auto fail back drbd setup?

Would you recomment a Ubuntu Server as an ZFS Storage VM or should i go with Solaris(OmniOS)?

thanks for the video theurbanpenguin, but with the file configuration corosync.conf i have the nodes offline,both of them,i think i need to change something. im in ubuntu 18.04

So what if you run Nextcloud on this shared storage and managed as this setup. And then you upload many files, during the upload, the master reboots. This switches the roles of the slave to master. Then the slave (which is now the new master) is the one that can write stuff. But the old master still had some files on disk, not yet synced through DRBD. Is there then a problem with figuring out which files to keep or not? Since the DRBD master is what it says, it's the leading decision maker of what there is to sync, if this role switches a lot while you have unsynced files... Are some of these files then thrown away? Of course in this example, the client can resync the files it has to the cluster. But if this was a mailserver, then you don't want to end up with disregarded mail. Does this question make sense?

i'am found problem in partition. i need help

Everything is great. But you didn't explain the pacemaker configuration properly (all those long lines). Thank you for the video anyways.

Great explanation! Thanks!
