Re: downloading iso to secondary storage

[Swastik Mittal]

hey,

I tried with system VM template version 4.4 and it works fine. Earlier I
was using system VM template 4.6. Also when I used console to access SSVM
installed from 4.6 system VM template, each time I pressed enter after
entering the password machine used to reboot by itself. I used to access
SSVM through ssh from my local system and not console of management server.

downloading iso to secondary storage

[Swastik Mittal]

Hey,

I am downloading iso from local http server to secondary storage. Iso gets
registered succesfully but it does not show any status and is not
downloaded. After some time (~5-6 hrs) iso displays successfully installed.
Initially I was facing this error but that time iso was not getting
downloaded at all and it was because sshd service was not enabled on
secondary storage server. Generally status shows downloading percentage
when getting downloaded but my management server shows nothing. My
cloud.out does show no credentials configured for host but I can connect to
management and secondary storage from ssvm using ssh and in case of the iso
successfully installed same status "no credentials configured for host" was
shown. I am not able to identify whether iso is really getting installed or
there has been some connection problem because of which I have to wait for
hours. My secondary storage is mounted and the mounted directory have 777
permission. Any idea?

Re: System VM Issues 4.11?

[Rohit Yadav]

Thanks Kristian,


Please confirm:

- Did you see the new 4.11 systemvmtemplate and tried to destroy old systemvms 
and/or virtual routers?

- Are all the xenserver hosts version 7.0 in all your clusters?

- Was the upgrade in-place (on the same host), or on a different server?

- Is dynamic roles enabled or you're still using the old/deprecated static 
roles i.e. commands.properties file?

- Did you try accessing the UI in incognito mode or after clearing the browser 
cache?


Looking at the logs, some errors:

This looks like a case where an old (pre 4.11) or new (4.11) based virtual 
router ended up having read-only file system. If there are old virtual routers 
they need to be removed, restart network with cleanup=true.

I'm not sure why your mgmt server was unable to make a connection with existing 
xenserver host. After a major version upgrade, on reconnection scripts will be 
copied to your xenserver host. In case that failed (because I don't have your 
upgrade logs), you'll need to reset host flags and reconnect on all such hosts.

Not sure about these ones.

Can you check if your storage pools are accessible to your hosts?


Lastly, if you attempt upgrade again (or perhaps on a test environment), do 
keep the logs for future reference for example sharing with us in case it fails 
for you again.

Hi Kristian,


Yes, can you share the logs and if you saw any sql/db or other errors when you 
tried to access the UI?
