Ok, I had stop the verify runs on all of the volumes where I didn't do an initial sync. Then I ran a forced sync on each of them and they ran to completion. I then patched the passive peer (shutdown the mirror). When I the patching was done and the secondary system was rebooted, I then restarted the mirror and it started to do a full sync. This is not what I had expected. The "oos" was the entire volume for all of the new devices.

If you have run a verify, then all the out-of-sync blocks are marked. cat /proc/drbd should show very large numbers of "oos" (Out Of Sync) blocks. Simply disconnect/reconnect the resource and it will resync the out of sync blocks in the proper direction. The disconnect/reconnect can be done on the Primary or Secondary, it doesn't matter. Forcing a sync will sync all blocks, but your verify has already determined which need to be updated. It will be faster, but still quite a lot of data, I'd imagine. You will want to do the disconnect/reconnect at a low-use time of day, but I'm not sure waiting for the weekend is a good idea. You have no reliable redundancy until the oos count is zero. Verify only marks oos blocks and produces a message - it doesn't change the status of the disks. hth Dan -----Original Message----- From: drbd-user-bounces at lists.linbit.com [mailto:drbd-user-bounces at lists.linbit.com] On Behalf Of Prater, James K.

I have created mirrors, between two peers (active/passive) but did not do the initial sync. I was going to wait until the weekend to do that. However I had forgotten that I had placed "drbdadm verify all" in my cron, and not it is verifying. It had marked the volumes "UpToDate". My question are these volumes really "UpToDate" or will I have to run "drbdadm primary --force", or actually invalidate one then force the synchronization?
