Citrix XenServer crashed?

Question

API

The situation is as follows, on the server an array of 5 RAID 5 disks, one disk failed and citrix refused to start without the fsck operation.
Citrix XenServer 5.5
Replaced the disk in the array, everything worked out and checked, after which I performed fsck and citrix started up.
But now when starting Citrix it gives an error

The underlying Xen API xapi is not running. This console will have reduced functionality. Would you like to attempt to restart xapi ?

Press YES
But still won't start

Restart Failed<br/>
Xapi did not restart seccessfully. More information may be available in the /var/log/messages

And now all network settings, etc. are down.
And the worst thing is that I don’t see my virtual machines there, there were 2 virtual servers on this server, what should I do?

Answer 1

Rearrange xen server and restore virtual machines from backup.
With your treatment methods in the comments, without logs, complete nonsense.

Answer 2

Can't read, writes primessisions dinded. Although I'm sitting under the root.

Answer 3

cat /var/log/messages showed a lot of things, but I don't know how to post them here

Answer 5

Already read
df -h
Filesystem
/dev/sda1 size-3,8GB / Used 1.7GB / Avail 2.0GB
This is very suspicious, since I have a raid from 930GB What to do is not at all clear

Answer 6

And whence 930 on 5th from 250 disks?

Answer 7

Array Size 930.8 GB
This is not invented but taken from Adaptec Manager. In any case, there is not 3.8 GB

Answer 8

Deleted everything from the /var/log folder did not help

Answer 9

XAPI solved the problem with the message crash as follows:
deleted the /var/xapi/state.db file
This message no longer crashes, but still now I don’t see network interfaces or virtual machines. What to do ?!

Answer 10

First, I would check to see if LVM is in there. pvscan/lvscan
If the local storage is alive, then it's probably worth reinstalling Xen, but without choosing disks to create storage on the installation. And then connect the old storage, create new virtual machines and attach disks from the old ones to them.

If it doesn't open, find it in the Google cache.

Answer 11

Fulfilled point 10 of this article support.citrix.com/article/CTX120962
picked up Local Storage but anyway when I go to the list of VM's, not a single VM is there.
