Stop flexVDI Agent
Code Block # service flexvdi-agent stop
Unregister the host: remove the file that stores the registration key.
Code Block # rm /etc/flexvdi/flexvdi-agent-key
- Then you can run flexvdi-config and register the Host with the flexVDI Manager.
Start flexvdi-agent again, so that it loads the new configuration
Code Block # service flexvdi-agent start- Login each host, run flexvdi-config, and run the "Manager->Refresh keys" option.
Q: Connecting to host with ssh is slow (10 seconds). Creating new guests takes 10 seconds too. flexVDI-Client fails to connect to stopped guests with a timeout.

Q: OCFS2 volume is not mounted, and it was working until the last reboot.
If flexvdi-agent.log shows lines like:
| Code Block |
|---|
[01/Jan/2021:01:02:03] [WARN] vol_mon: Cannot mount primary disk /dev/sdc |
And dmesg shows:
| Code Block |
|---|
[471392.669767] o2net: Connected to node labnode01 (num 0) at 10.200.100.8:7777
[471398.669537] o2net: No longer connected to node labnode01 (num 0) at 10.200.100.8:7777

Probably the problem is that a new kernel has been installed, but a OCFS2 kernel for the current kernel version has not been installed.
Check if ocfs2 kernel module is running with:
| Code Block |
|---|
[root@flexdev02 ~]# lsmod | grep ocfs2
ocfs2 1058079 1
jbd2 107478 1 ocfs2
ocfs2_dlmfs 23358 1
ocfs2_stack_o2cb 13279 1
ocfs2_dlm 165899 1 ocfs2_stack_o2cb
ocfs2_nodemanager 223720 12 ocfs2,ocfs2_stack_o2cb,ocfs2_dlmfs,ocfs2_dlm
ocfs2_stackglue 17171 3 ocfs2,ocfs2_stack_o2cb,ocfs2_dlmfs |
You should see a line starting with ocfs2. If you don't, you are missing the ocfs2 kernel module required to mount ocfs2 filesystems. Information about installing it is available at Updating flexVDI software
