I've set up drbd on 2 nodes. 1 of them behave abnormally recently so I tried to remove drbd on that node, hoping to configure it again, but it stopped me to do so.

When I tried "yum erase drbd", I got: "No Match for argument: drbd, No Packages marked for removal"

And when I tried "yum install drbd" I got:

--> Processing Conflict: drbd conflicts drbd82
--> Restarting Dependency Resolution with new changes.

drbd-8.0.16-5.el5.centos.i386 from extras has depsolving problems
--> drbd conflicts with drbd83
Error: drbd conflicts with drbd83

What is drbd83? Is it a bug or something?
Any help will be appreciated! Thank you very much.

Interesting.


To see what you have installed.
Then

This drbd is very popular on LQ, in the newbie forum.

drbd82-8.2.6-1.el5.centos is installed. And when I do "yum search drbd", I got:

Any idea??

Right so you have drbd82 installed. So refer to the package with that name and you can't go wrong.

rpm -e drbd82
yum install drbd82

Thanks for the kind assistance. But now I got another problem: the nodes just don't connect.

m:res cs ro ds p mounted fstype
... sync'ed: 0.1% (99928/99944)M
0:r0 SyncSource Primary/Secondary UpToDate/Inconsistent C /mnt/drbd ext3



It seems the sync stalls... I tried "drbdadm -- --discard-my-data connect r0" on the secondary node which seems to have 'bad' data, but it still doesn't work. Any idea? Thanks in advance.

Sorry, I have never used drbd. Not really sure what it is let alone know how to configure it.

Hopefully someone else can help.

Oh! Thanks anyway!
