Hello Guys,Well you have one foreign object in there that is not part of the
I've having some trouble on a new system I'm setting up. I'm getting a
kernel BUG message, seems to be related with the use of Xen (when I
boot the system _without_ Xen, I don't get any crash).
Here is configuration :
- 3x Hard Drives running on RAID 5 Software raid created by mdadm
- On top of it, DRBD for replication over another node (Active/passive cluster)
- On top of it, a BTRFS FileSystem with a few subvolumes
- On top of it, XEN VMs running.
The BUG is happening when I'm making "huge" I/O (20MB/s with a rsync
for example) on the RAID5 stack.
I've to reset system to make it work again.
Reproducible : ALWAYS (making the i/o, it crash in 2-5mins). Also
reproducible on another system with the same hardware.
Kernel versions impacted (at least): kernel-4.4.26, kernel-4.8.15, kernel-4.9.0
kernel and which shows up in the OOPS: DRDB
What happens when you remove that from the equation?
