Hi, I'm new to DRDB, and I think it's really a great solution for data redundancy/protection. It was surprising easy to install (although there's a lot of out-dated documentation on the website that can be confusing to newbies). I have a question. From reading the mailing list, I know a lot of people are trying to mount a drbd resource as readonly on the Secondary, and all documentation says it's not possible (or, it shouldn't be done). I think my need is a little different. I want to turn off drbd on the secondary long enough to make a remote backup of the contents (using Bacula). I've found that if I shut down drbd on the secondary, mount the "low level device" in readonly mode, I can perform a backup of the data just fine. Then, when I umount the low level device and start drbd again, the system seems happy. Is this a really bad idea? I think I read somewhere that we shouldn't touch the low level device, but since I'm using readonly and the device isn't being updated by drbd, is this safe to do? The reason I want to do this is to take the backup load off the primary. Thanks for your thoughts, Michael (oh, and if someone has already answered this, please point me to the thread. I went back a few months and didn't see anything that dealt with my particular situation)
