<div>Hi.</div>
<div> </div>
<div>I'm very new to drbd. In fact, I'm still testing it.</div>
<div> </div>
<div>I'm using openSuse 13.2. I could configure drbd in both machines and seems to be working well but ...</div>
<div> </div>
<div>The problem occurs when I try to reboot the 'primary' machine - the one that have the primary or active file system. It cannot simply boot.</div>
<div> </div>
<div>It can boot if a take the device out from <span style="font-family: 'courier new', courier;"><strong>/etc/fstab</strong></span> and mount it after boot:</div>
<div> </div>
<div>
<div><span style="font-family: 'courier new', courier;">UUID=9585d7b4-fac5-4f19-aea3-95debdf86481 swap swap defaults 0 0</span></div>
<div><span style="font-family: 'courier new', courier;">UUID=9c052c13-c838-4488-959f-c0d5ef16377d / xfs defaults 1 1</span></div>
<div><span style="font-family: 'courier new', courier;">UUID=2dc37455-631e-48da-a308-990d2b6a404c /boot ext4 acl,user_xattr 1 2</span></div>
<div><span style="font-family: 'courier new', courier; color: #ff0000;"><span style="font-size: medium;"><strong>#</strong></span>/dev/drbd0 /dados ext4 acl,user_xattr,usrquota,grpquota 0 0</span></div>
<div> </div>
</div>
<div> </div>
<div>I also tried to make sort of 'manual mount' after boot using <strong><span style="font-family: 'courier new', courier;">/etc/rc.d/after.local</span></strong><span style="font-family: 'courier new', courier;"><span style="font-family: arial, helvetica, sans-serif;">, using the mount command:</span></span></div>
<div><strong><span style="font-family: 'courier new', courier;"> </span></strong></div>
<div><span><span style="font-family: 'courier new', courier;"><strong>mount -o acl,user_xattr,usrquota,grpquota /dev/drbd0 /dados</strong></span></span></div>
<div> </div>
<div>but even so I could not boot because the device drbd0 seems to be very lazy if I interpreted correctly this peace of log:</div>

<div> </div>
</div>
</div>
<div>I could circunvent this behaviour configuring <span style="font-family: 'courier new', courier;">systemd</span> in order to only execute the script <span style="font-family: 'courier new', courier;">/etc/rc.d/after.local</span> after <span style="font-family: 'courier new', courier;">drbd</span> initialization but I think that the mount should be executed from <span style="font-family: 'courier new', courier;">/etc/fstab</span> code as usual in linux systems.</div>
<div> </div>
<div>Can anyone give me some help?</div>
<div> </div>
<div>Thanks.</div>
