[BETA] [HPE] StoreOnce error during HPE-VME parallel full backup

[yumi.tazawa]

In a VME cluster environment, running 8 parallel full backups on 2 workers results in the following error.
This does not occur when performing 4 parallel full backups, or 8 parallel incremental backups, or 8 parallel full backups when the bandwidth limit(2.5Gbps or less).
I have sufficient network bandwidth in this environment. What problems could there be?

Error:
Failed : hpe-test-w2025-3 : Failed to perform backup: OSCLT_ERR_SERVER_OFFLINE.
Err: -1404 Failed to write data to the object [[xx.xx.xx.xx] StoreTest01:/hpe-test-w2025-3_Backup_3/hpe-test-w2025-3_Backup_3_2026-02-24T183304.vbk].

Environment:
HVM VME 8.0.12 : HVM Host*14 40Gbps(10Gbps*4 LACP)
StoreOnce 5660 : 20Gbps(10Gbps*2 LACP)

Hello,

This error seems to be coming from the StoreOnce and isn't related to the plugin. Do you have a dedicated gateway server for the StoreOnce? If not, the backup server is likely acting as the gateway and it would probably be better to deploy a dedicated VM/server to use for the data transfer. I can reach out to you to collect the logs.

Do you use the StoreOnce for any other VBR servers protecting other workloads?

Hello,

In this environment, the backup server is used as a gateway server. In that case, is a lack of resources an issue?
Is it recommended to set up a dedicated gateway server?
I have sent you the log, please check it.
StoreOnce is used for this job only.

Hi @yumi.tazawa what was the outcome of this issue? Facing similair issues (not entirely the same setup though)

Can you share your issue? It might also be helpful to open a support case. This subforum is mostly related to our KVM/Linux Hypervisor integrations (HPE VME, oVirt, etc). If you're seeing StoreOnce errors, that is usually either on the storage appliance, the gateway server or the network somewhere.
