SR_BACKEND_FAILURE44 Insufficient Space

SR_BACKEND_FAILURE44 Insufficient Space

2 Xenservers 5.6, using Dell Equalogic iSCSI SAN storage. There are 4 SR's that are presented to the cluster. All have a lot of VMs running but there is some space available and we arent hitting the disable thresholds.

 

However i cannot create any VMs - this has got worse since upgrading the system VMs (These were stuck on v3 and not 4.2). I was getting errors pointing to an issue with VHD-Util so i recopied that to the hosts and the errors are now like Host Plugin Failures and SR_BACKEND_ERROR44 Insufficient Space.

 

The SR it was trying to use was full but shouldnt it try and use one of the others ?

 

Also ive noticed we have quite a few volumes that are in the "Destroy" state when you check the DB - before and after the System VM upgrades. Shouldnt these say "Expunged" ?

 

I seem to go from one issue to another so any help would be appreciated as at the moment i cant create anything despite 2 of the SRs having space.

 

Thanks!

Matthew, sorry to hear about your troubles. I will try my best to help you out here on the forum but I do recommend that if you have a support contract with Citrix then better report an incident with them as well.

 

Please answer the following questions:

1. At the moment, is any SSVM running (agent status is reported Up) in the zone you are deploying the VMs in?

2. Are you using storage tags?

3. I need more information about the available space, both in the DB and as reported in mgmt server logs during deployment. How can you share that information?

Hmm, are you able to specifically nail down the step in the VM deployment operation where it fails. I am not sure if this issue is related storage getting full, the error message might be misleading. I could really help if I could get my hands on the management server logs and/or SMlogs.

 

Can you open a ticket with support so we can have a deeper look at the issue?
