Hi there A scripted backup running on one of our XCP installations failed a few days ago, while exporting a snapshot. After the failure I tried to delete the snapshot in question, to no avail (something about the VDI being in use).
Anyway, I thought an xe-toolstack-restart would reset any lock on that file, allowing me to delete the no longer needed snapshot. Unfortunately, xapi is now unable to start. I've just tried again, and this appears in /var/log/messages: Jan 20 11:01:21 xcp-hoppe xapi: [ info|xcp-hoppe|0 thread_zero||watchdog] (Re)starting xapi...

I'm somewhat desperate, as I'm unable to perform any xe commands and am worried a reboot of the server will not magically bring xapi back online, meaning the VMs will not start. This XCP host is critical to one of our customer's infrastructure. It's Friday and I could possibly go there this evening and perform tasks necessary to bring everything back online, I just don't quite know what my options are, aside from reboot and perhaps an in-place install of XCP. Does anyone have any bright ideas? I'm all ears!
