Thanks for the information. Just want to clarify a few points to make sure I understand. In the following case - Node A Primary and Node B Secondary.

Can I run tune2fs -c -1 -i 0 /dev/drbd0 on Node B since it is not mounted to /shared. Or do I have to unmount /shared on Node A before I can run the tune2fs? In other words, does /dev/drbd0 have to be NOT mounted on either node? > > or fsck the DRBD. > -> umount /shared, fsck drbd0, mount /shared. Same thing here can I fsck /dev/drbd0 on Node B or do I have to make sure that the /dev/drbd0 device is not mounted on either node. > > as you say you use heartbeat in haresources mode, > that should be straight forward. > > if you where in CRM mode, you'd need to set the target role of the > Filesystem to stopped temporarily, or set it to unmanaged. > > -- > : Lars Ellenberg > : LINBIT | Your Way to High Availability > : DRBD/HA support and consulting http://www.linbit.com > > DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. > __ > please don't Cc me, but send to list -- I'm subscribed > _______________________________________________ > drbd-user mailing list > drbd-user at lists.linbit.com > http://lists.linbit.com/mailman/listinfo/drbd-user
