Hello everyone
*Please Urgent, my servers are in production*
I am in a serious problem and need help
*My my scenario*
- I have two workstations ASUS P8H77-M PRO with Intel core I7, Proxmox VE
2.3, DRBD 8.3.10, LVM on top of DRBD
- 2 NICs Realtek RTL8111/8168 PCI-E of 1 Gb/s in bond round robin only for
use with DRBD
And after awhile it shows me this:
shell#cat /proc/drbd
version: 8.3.13 (api:88/proto:86-96)
GIT-hash: 83ca112086600faacab2f157bc5a9324f7bd7f77 build by root at sighted,
