Issue
A XenServer node is not available in the pool - all VM's running on the server have stopped/migrated to other nodes.When logging into the server via the DRAC card the following message is displayed:
"The XenA API xapi is not running. This console will have reduced functionality."
Resolution - lifted from http://support.citrix.com/article/CTX128316
- The most common cause is that the XenServer disk has ran out of space. Usually because a log file has grown especially large.
- Open the console via Putty/any SSH terminal (The server will not be available in XenCenter)
- Typr df in the console - this will show you the current disk use - you will see a "Use%" listed as the 5th column, if this shows at or very near 100% then disk space is probably the issue

- The most common cause of disk space being used is the logs in /var/log so do the following:
- cd /var/log
- Run the following command to see the size of all the files in the current directory; narrow down your search by specifying one file, if needed:
- du –ksh *.*
- If you see an excessively large file, run the following command to delete the file:
- rm <filename>.log.
- Restart the XenServer to recreate the log file and it restarts XAPI automatically.
