Title: ProActive Software
Hi,

Normally, you would do your 'mkfs' after you initialized the drbd disks.

Did the synchronisation run after your 'drbdadm -- --overwrite-data-of-peer primary' command?

It should have, the log messages:

kernel: [ 1351.610453] block drbd4: role( Secondary -> Primary ) disk( Inconsistent -> UpToDate ) pdsk( DUnknown -> Outdated )

kernel: [ 1351.611116] block drbd4: Forced to consider local data as UpToDate!


Are normal after a 'drbdadm -- --overwrite-data-of-peer primary'.

Cheers,

Dirk

Dears,

I use drbd in two machines connected


I executed the comands in second node :
modprobe drbd
/sbin/drbdadm create-md partition4
/sbin/drbdadm up partition4

In primary node i executed :
modprobe drbd
/sbin/drbdadm create-md partition4
/sbin/drbdadm up partition4

/sbin/

kernel: [ 1351.610453] block drbd4: role( Secondary -> Primary ) disk( Inconsistent -> UpToDate ) pdsk( DUnknown -> Outdated )

kernel: [ 1351.611116] block drbd4: Forced to consider local data as UpToDate!

mkfs /dev/drbd0

In /var/log/syslog
The log show:

Executing '/sbin/drbdadm -- --overwrite-data-of-peer primary partition4'

kernel: [ 1351.610443] block drbd4: Not fencing peer, I'm not even Consistent myself.

Anyone seen this problem in the log? can you help me?


My global_common.conf :


global {

usage-count yes;

}

common {

protocol B;

syncer {

rate 100M;

al-extents 3389;

}

handlers {

outdate-peer "/usr/lib/heartbeat/drbd-peer-outdater";

split-brain "/usr/lib/drbd/notify-split-brain.sh root";

}

disk {

on-io-error detach;

fencing resource-only;

}

net {

after-sb-0pri discard-zero-changes;

after-sb-1pri discard-secondary;

after-sb-2pri disconnect;

max-buffers 8000;

max-epoch-size 8000;

sndbuf-size 0;

}

}


Best reguards,
