host node reboots by itself and keeps waiting for umount.

[WXR <14...@qq.com>]

I find that my cloudstack host node reboots by itself sometimes.
I think the reboot message may be sent by management or agent service.

And if the host node reboots by itself,it always stops at this line:
umount.fs /mnt/1edaca6a-b5dc-414d-90f3-0e0ddc6092d0   device is busy [failed]

1.Why does the host node reboot by itself,how to avoid it?
2.How to let cloudstack host node reboot normally,it often stops at umount failed line.

to me it sounds like your host is losing connectivity to primary storage,
which makes cloud stack management server start to think that vms are
stopped / frozen which triggers it to reboot the host to resolve such issue.
