Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.
We have problems with our three node DRBD 9 setup with CentOS 7 and Xen
4. When one of our nodes is rebooted, or becomes unavailable, the other
nodes freeze entirely without any information, or give the following
message:
kernel:NMI watchdog: BUG: soft lockup - CPU#2 stuck for 22s!
[drbd_w_db:1469]
They then require a reboot, sometimes crashing one of the other nodes
again in the process. Not a fun thing in a HA setup...
Does anyone have an idea what is going on, and what we can do to prevent
this from happening?
We are running:
DRBD 9.0.4-1 (api:2/proto:86-112)
CentOS 3.18.41-20.el7.x86_64
Xen 4.6.3-3.el7
I do not know if it is related, but we are using bonding (mode 1,
active-backup) with two network adapters.
