XenServer "xe" command doesn't exist.

[Vincent Dice]

From Xenserver CLI I can execute no xe commands.  I get "command not found".  I had no problems previously when I set up the server but during an update, XEN filled up one of my partitions and wounded all kinds of stuff.  I deleted the space hogs but despite this, I constantly get SR Failed when trying to scan, detach or do anything.  It was after this I noticed xe is not available.  I found a symlink that points to /opt/xensource/bin/xe but only /opt/xensource/ exists and no deeper.  I definitely did not delete this folder as I only deleted an ISO installer from a mount under the root (/vm/iso/DVDimage.iso).  I feel a reboot would do the trick but with all the issues I'm having after the space-hog, I'm reluctant to attempt it as the server is in production and 2 hours away from me.  I'm worried it won't come back up.  Any thing I can try?

New.  When attempting to start a VM I also get SR failed to complete operation.  It's broke as crap.

I would strongly suggest re-installing the OS from scratch. Clearly, something got corrupted. Maybe in/var/log there is an indication of some major error.

You didn't mention which version of XS you are running, but newer (strarting with 7.X) versions allow for a much better partition layout that could better prevent bad things from happening if, say, the log partition fills up (as opposed to the logs going under the root partition).

Thanks, Tobias.

I'm inclined to agree with your suggestion.  I rebooted it, reluctantly, and now all kinda things are broke.  Can reach the xsconsole via CLI but getting

 xapi-nbd[10251]: main:   "Failed to log in via xapi's Unix domain socket in 300.000000 seconds") errors now.  No response when trying to connect XenServer.  Verion 8.2 BTW.

Vincent,

It does not sound healthy. Better to run with a system you know that installed properly and was stable to begin with.

If XAPI can't start it could be because you are out of space or it could be some file issues 

going on. A reinstall is probably a good suggestion.  If you are on a single drive be sure

to verify its integrity as well.
