SimpliVity OmniCube Available Physical Capacity 20 Percent or Less

[FMM-ExploitIT]

Hello,

In our infrastructure, we have 10 SimpliVity nodes. Two of them, nodes 2 and 5, are heavily saturated at 84% storage utilization (warning: SimpliVity OmniCube Available Physical Capacity 20 Percent or Less), while the others are at 17% and 11% !!

I’ve tried manually moving some of the virtual machines (S “hives”) to a less utilized node, but they keep reverting back. I’m not sure why this is happening. 

to be able to manually balance the load I also tried to disable svt-iwo and dsv-balancer and DRS, but same problem when I move the secondary replica after a while, the moved s replicas back to the nodes 2 and 5 saturate again up to 84%!! since other nodes are in 17% and 11% and 16%!!

My question is whay the moved S replicas back to the nodes 2 and/or 5 ?, is ther any possibilité to change the placement of S, P hives and the owner of the P hive ?  

Thank you in advance.

Hello, 

I have shis States on my balancer show : dsv-balance-show --shownodeindex --autobalancers : 

Linked clone balancer V2 | UNBALANCED

Dire Space Balancer | UNBALANCED

Space Variance Balancer | UNBALANCED

Thank you for your question: 

Many factors actually and further investigation into your system would be required by support to find the exact culprit - feel free to create a case with the SimpliVity support team via (https://support.hpe.com/connect/s/?language=en_US) 

It could also be the vmWare service DRS and the affinity rules applied:

As I work with folks new to the SimpliVity environment I always request that they become familiar with their 'svt' & 'dsv' commands. (such as dsv-balance-show --status) This will help discover/locate items within their systems. 

Let us know if you have any issues confirming and or creating a support case with the SimpliVity team for we would love to help and get that federation balanced. 

Thank you.

Good day, 

I am checking in to see if you have been able to create a case with the support team and also confirmed the status. 

Capacity cases are usually the most fun as far as issues to resolve as I am concerned for the resolutions can be several options. It could even boil down to the type of VM or something over the network. 

Let us know if any further support can be provided, thank you.

Hello Joshua610,

Thank you very much for the answer, for 1 year we have created many support tickets, but they have not solved your problem.

Our problem is storage saturation not compute, so to be able to manually balance the load I tried to disable svt-iwo and dsv-balancer and DRS, but same problem when I move the secondary replica after a while, nodes 2 and 5 saturate again up to 84%!! since other nodes are in 17% and 16%.

NB : We have two availability zones of 5 nodes each and 16 datastores, as you can see in the details below, the available size in node 2 and 5 is very small since other nodes have large free space, manual balancing did not work as it reverts to these two nodes after few hours.

SIZE(G)    2926.2  6544.5  970.9  1800.3  5603.4  3026.1  1048.0  947.3   969.5   1037.6
AVAIL(G) 1128.4  612.1      1692.6  1235.9   752.3     1074.7  2194.6  2044.1 2073.7 2187.1
