<p><font size="2" face="sans-serif">Hello,</font><br>
<br>
<font size="2" face="sans-serif">So my problem is that I want to use /dev/disk/by-label/ to have persistent links in the .res file. For example, my res file would have "disk /dev/disk/by-label/p1" instead of "disk /dev/vda4". This worked fine before with RHEL5 and drbd 8.2.6. However, with RHEL 6.2 and drbd 8.4.0 I've noticed that when service drbd start runs it sometimes removes the links from the by-label directory and they don't necessarily come back when drbd gets stop. See my demonstration below. Does anyone have experience with this problem that could offer some advice on why this happens? </font><br>
