Hello, I am having some troubles setting up a stacked resource on drbd 8.4.1
with debian. If I do this exact same process with 8.4.0 it works.
I'm testing it on a vm under vsphere 5.0. I configured the vm as follows:
os: debian 2.6 x 64
cpu x 2
mem 1gb
hard disk1: 512mb
hard disk2: 512gb
network1 on vmnetwork (connected to the real network)
network2 on vmprivatenetwork (not connected to any physical network, just
for traffic between vms)
I installed debian with simple one partition setup on disk1, didn't install
any additional packages, hostname drbd.
created single partition on disk2 using all available disk space.
did the following to install drbd 8.4.1:
aptitude install make gcc flex linux-headers-$(uname -r) -y
wget http://oss.linbit.com/drbd/8.4/drbd-8.4.1.tar.gz
tar -zxvf drbd-8.4.1.tar.gz
cd drbd-8.4.1
./configure --with-km --sysconfdir=/etc --localstatedir=/var
make
make install
<<reboot>>
here is my resource definition:
#meta.res
resource meta_lower {
disk /dev/sdb1;
device /dev/drbd0;
meta-disk internal;
on drbd{
address 10.50.158.1:7788;
}
on storage2 {
address 10.50.158.2:7788;
}
}
resource meta {
protocol A;
device /dev/drbd10;
meta-disk internal;
stacked-on-top-of meta_lower {
address 10.50.158.101:7788;
}
on openfiler3 {
disk /dev/sdb1;
address 10.50.250.4:7788;
}
}
at this point i don't have any other vms created so we're just dealing with
the one system.
next i issue the following commands to bring up the resource for the first
time:
drbdadm create-md meta_lower
service drbd start
drbdadm primary --force meta_lower
drbdadm --stacked create-md meta
drbdadm --stacked up meta
everything works ok until the last command then i see this on the console:
BUG: soft lockup - CPU#0 stuck for 61s! [drbdsetup:1229]
eventually this is the result shown in the command line:
root at drbd:~# drbdadm --stacked up meta
Command 'drbdsetup attach 10 /dev/drbd0 /dev/drbd0 internal' did not
terminate within 121 seconds
