Re: [Xen-users] live migration breaking...aoe issue?

[Marcelo Messa <mrmessa@xxxxxxxxx>]

"aoe-stat" command will show the state of your disks.

AoE have a 300 seconds for default timeout.  Try set aoe_deadsecs to  
30 seconds (or less if is your intention).
You can set aoe_deadsecs from command line (echo in /sys), with  
sysctl or with a parameter to module (you can put in /etc/ 
modprobe.conf "alias aoe aoe_deadsecs=30".
