le sed magic and you're set up.
- neither the documented nor official hidden commands of drbdadm seem
to be able to return this information
what about:
$ drbdadm role vm-file
Primary/Primary
Primary/Primary
(resource vm-file here has 2 volumes)
Any idea appreciated.

Hi
@Cesar: thx for your suggestion - but i don't want to do a manually fence.
from Digimer's replies to your posts:
1- the dlm lock will be released once the crashed node is set to a
*known* state in pacemaker. Without releasing, forget about using
} migrate_to timeout=120s interval=0
the commands use pcs but you can easily translate them to crm.
good luck

But when I check performance values I do not see any bottlenecks:
-CPU IO wait is below 2%
-CPU itself is ~98%idle
-network is not busy at all.
Anyone having a clue why this is so slow?

Hi all,
Here is my problem :
I've got two servers connected via a switch with a dedicated 1Gb NIC. We
have a SSD raid 1 on both servers (software RAID on Redhat 6.5).
Using dd command I can reach ~180MB/s (dd if=/dev/zero
/converged-network-adapters/ethernet-x520-qda1-brief.html
At those speeds it would be interesting to test the upcoming 3.18 kernel
with the bulk network transmission patch [1] ; that should save you a
bunch of cpu cycles.

I am planning to use DRBD with Advanced Format WD hard drives which have 4KB
physical sector. Should I suspect a significant performance degradation in this
case? All partitions will be aligned on 4KB boundary.
Thanks for any help,

the
solution to have more memory available was to write the dirty page to
disk.
If someone has some information about that problem I'am eager to read
it.
Thank you in advance.

I hope this clarify the problem.
Correct me if I have made wrong assumptions, I just want to have the
conviction that this cannot happen in production.

result of calling drbd_send_uuids() within after_state_ch().
Any help is much appreciated.

User's guide, whilst man file for drbdadm does
not mention it.
3. After DRBD starts process of synchronisation, can I mount block
devises on the master node, or do I have to wait until synchronisation
is completed?
Thank you very much for your help.
