(very long) A problem using 0.6.1-pre6 on 2.4.13-smp kernel
contact at example

I'm trying to install drbd 0.6.1-pre6 on a 2.4.13 kernel, smp, 1Gb ram.

When compiling I see

gcc -c -g -D__KERNEL__ -DMODULE -O2 -Wall -fno-strict-aliasing -mpreferr
ed-stack-boundary=2 -march=i686 -DCPU=686 -Wstrict-prototypes -Wno-trigr
aphs -fomit-frame-pointer -fno-common -pipe -I/usr/src/linux/include -D
__SMP__ -DMODVERSION -DCONFIG_MODVERSION -DEXPORT_SYMTAB -DAPI_VERSION=5
8 -DPRO_VERSION=60 -DREL_VERSION=\"0.6.1-pre6\" drbd_syncer.c
drbd_main.c:953: warning: function declaration isn't a prototype
drbd_main.c:980: warning: function declaration isn't a prototype
/usr/src/linux/include/linux/blk.h:358: warning: `do_nbd_request'
declared `static' but never defined

(the different command line for gcc is a test of mine, I tried the plain
cvs
distribution, too, with identical problem as described below).

and a depmod -a says

depmod: *** Unresolved symbols in
/lib/modules/2.4.13-64Gb-SMP/kernel/drivers/block/drbd.o

but the module load.

I start drbd on two servers (asso1 and asso2) and the sycronization
process finish
without problem. As phisical unit I use /dev/md4 (software raid) on both
servers.
mke2fs /dev/nb0 doesn't report errors.

Using the network disk, however, is almost impossible.
Without using the disk, I find in the syslog these lines:

The disk is only mounted (primary asso1), but not used.

Then I try some write...

asso1:/cluster # time dd if=/dev/zero of=test bs=4k count=1
1+0 records in
1+0 records out

real 0m0.110s
user 0m0.000s
sys 0m0.010s

(no problem)

asso1:/cluster # time dd if=/dev/zero of=test bs=4k count=10
10+0 records in
10+0 records out

real 0m0.458s
user 0m0.000s
sys 0m0.000s

(again, no problem)

asso1:/cluster # time dd if=/dev/zero of=test bs=4k count=100
100+0 records in
100+0 records out

real 0m6.490s
user 0m0.000s
sys 0m0.000s

(ok, but I think it's slow)

asso1:/cluster # time dd if=/dev/zero of=test bs=4k count=1000
1000+0 records in
1000+0 records out

real 0m33.107s
user 0m0.000s
sys 0m0.080s

Here syslog starts to report

The problem is not the network, I use a crossover cable on a dedicated
network card to join servers. Also, disks are fast:

asso1:/cluster # time dd if=/dev/zero of=/test bs=4k count=1000
1000+0 records in
1000+0 records out

real 0m0.560s
user 0m0.000s
sys 0m0.180s

Servers are dual pentium 3 processors.

drbd.conf is

resource drbd0 {

protocol=B
fsckcmd=fsck -p -y

disk {
do-panic
disk-size=12209280
}

net {
sync-rate=12000
# here I tried default value, 2500, 5000, 10000 as sync-rate
tl-size=512
# tried default tl-size
timeout=60
connect-int=10
ping-int=10
time=5
}

on asso1 {
device=/dev/nb0
disk=/dev/md4
address=192.168.0.1
port=6004
}

on asso2 {
device=/dev/nb0
disk=/dev/md4
address=192.168.0.2
port=6004
}
}

Could anyone help me to solve this problem?
Excuse me for the long message, but I would to send more info
as possible on the situation.

Thanks
Valerio

Your kernel has support for 64GB ram. Hmm, this enables himem support and
device drivers like DRBD have to deal with bounce buffers. -- Sorry this
is simply not done yet.
For now: DRBD only works when himem support is disabled.

PS: It should be rather easy to do, in Rubini's book is a good explanation
about this, I think.

Ok, now I don't see disconnections in the syslog :-)

Only two more questions:

- It's ok a 5MB transfer rate on a dedicated 100Mbit eth?
- Why I find this in the syslog?

Oct 28 09:31:38 asso1 kernel: drbd0: transferlog too small!!
Oct 28 09:31:38 asso1 last message repeated 4 times
Oct 28 09:31:38 asso1 kernel: drbd0: tl messed up!
Oct 28 09:31:38 asso1 kernel: drbd0: Epoch set size wrong!!found=217
reported=1240
Oct 28 09:31:38 asso1 kernel: drbd0: transferlog too small!!
Oct 28 09:31:39 asso1 last message repeated 9 times
Oct 28 09:31:39 asso1 kernel: drbd0: Epoch set size wrong!!found=193
reported=2752
Oct 28 09:31:39 asso1 kernel: drbd0: transferlog too small!!
Oct 28 09:31:39 asso1 kernel: drbd0: Epoch set size wrong!!found=33
reported=288
Oct 28 09:31:40 asso1 kernel: drbd0: transferlog too small!!
Oct 28 09:31:40 asso1 last message repeated 8 times

And so on...

Thanks,
Valerio

Increase the tl-size value in drbd.conf, until theese messages diappear.
Start and 6000 and increase it in units of 2000
