Show SR Used For HA State on XO Storage Page

[evoelise]

It would be very useful to display the SR used for the HA state files on the Xo Storage page.

Currently you have a tag-pill for the (Default SR) could we also have similar for the HA SR?

[olivierlambert]

Sure, that would make sense.

[julien-f]

Any idea where this SR is defined in XAPI?

I don't see it on https://xapi-project.github.io/xen-api/classes/pool.html

[olivierlambert]

It's likely in the ha_configuration record of the pool.

[julien-f]

If someone has HA enabled, please show me the output of:

xe pool-param-list uuid=<pool UUID> | grep ha-configuration

[evoelise]

The ha-configuration setting is blank on both my pools with HA enabled.

[17:48 XCPNG01 ~]# xe pool-param-list uuid=6e75bf9d-5882-0bc8-071e-9f116e4d6774 | grep ha-configuration
                ha-configuration ( RO):

Also looking at the configuration for the pool the SR UUID for HA state files is not shown:

None of those settings match the SR for my HA files which is 24a6f2d9-8141-36f3-b415-c3966961d5f6?

The SR with the UUID as mentioned above for ha-statefiles settings does not exist:

xe sr-list | grep b3a798e8-24f4-489e-bbd3-749004d3f190`
No match

Something doesn't look quite right here?

This is the actual SR with my HA files:

Can you show us the full record of the SR used for your HA/heartbeat? (output of xe sr-param-list)

[evoelise]

OK I see the ha-statefiles setting relates to a VDI not an SR.

[olivierlambert]

So in theory, with the statefile UUID, we can find which VDI and then in which SR it's hosted.
