Hi, It seems drbd shows quiet asymmetric performance on "crossmounted" devices. I have two HP DL385 (server0 and server1) each with two drbd devices drbd0 and drbd1 synchronized over a dedicated gigabit ethernet crosslink between them. Server0 has drbd0 mounted and Server1 has drbd1 mounted. When I

[DRBD-user] DRBD full sync not happening

We are using DRBD 0.7.11 for replicating a disk partition in our Linux storage blades. The user is given an option to set the size of the partition during the blade installation. For example if the user's input is 2000 MB as the partition size, we do a resizefs (2000-132)M immediately after mke2fs

[DRBD-user] Activity log

Is there a method to repair the activity log? On my secondary server, when it boots up, the drbd init script reports "No usable activity log found". I did a "drbdsetup /dev/drbd0 invalidate" which forced a complete sync, and it is still reporting this error after another reboot. Is there a drbd c
