Hello,
we try to setup DRBD (0.7.10) on top of LVM2 (2.01.0)
on two Debian 2.4.29-vs1.2.10 (SMP) systems.
After configuration of the drbd resource and initialisation
of the drbd device on both systems all seems to be running fine
server01> cat /proc/drbd
version: 0.7.10 (api:77/proto:74)
SVN Revision: 1743 build by root at pcrz175, 2005-03-02 09:18:52
0: cs:Connected st:Primary/Secondary ld:Consistent
ns:0 nr:8192 dw:8192 dr:0 al:0 bm:4 lo:0 pe:0 ua:0 ap:0
server02> cat /proc/drbd
version: 0.7.10 (api:77/proto:74)
SVN Revision: 1743 build by root at pcrz175, 2005-03-02 09:18:52
0: cs:Connected st:Secondary/Primary ld:Consistent
ns:8192 nr:0 dw:0 dr:8192 al:0 bm:2 lo:0 pe:0 ua:0 ap:0
But if I try to create an ext3 filesystem on the /dev/drbd0 device,
following command kills server01:
server01> mke2fs -j -m 0 /dev/drbd0
mke2fs 1.35 (28-Feb-2004)
