Hi Guys,

I just started to use drbd 7.8 to replicate two servers (centOS 4.4).

Here is the configuration.

both servers use /dev/sda4 as drbd device.

[root at m2 ~]# fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14       12761   102398310   83  Linux
/dev/sda3           12762       13016     2048287+  82  Linux swap
/dev/sda4           13017       19457    51737332+  83  Linux

after do drbdadm primary r0 in primary server, the sync started and finished without problem (both consistent).

[root at m1 ~]# cat /proc/drbd
version: 0.7.8 (api:77/proto:74)
SVN Revision: 1725 build by root at m1, 2006-12-06 10:45:39
 0: cs:Connected st:Primary/Secondary ld:Consistent
    ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0

but when I  run mkfs.ext3 /dev/drbd0 on primary and try to mount the device the machine crashed and lost connection.

any helps will be highly appreciated!
