Hello guys,
I've recently came across the bug CLOUDSTACK-5429 which has rebooted
all of my host servers without properly shutting down the guest vms.
I've simply upgraded and rebooted one of the nfs primary storage
servers and a few minutes later, to my horror, i've found out that all
of my host servers have been rebooted. Is it just me thinking so, or
is this bug should be fixed ASAP and should be a blocker for any new
ACS release. I mean not only does it cause downtime, but also possible
data loss and server corruption.
Hi Andrei,
Do you have HA enabled and did you put that primary storage in
maintenance mode before rebooting it?
It's my understanding that ACS relies on the shared storage to perform
HA so if the storage goes it's expected to go berserk. I've noticed
similar behaviour in Xenserver pools without ACS.
I'd imagine a "cure" for this would be to use network distributed
"filesystems" like GlusterFS or CEPH.
