HA Problem

[TanerKaragol]

I have installed version 16u1 on Rocky 9.x
TrinityX documentations says:
"the HA directory /trinity/ha (default of trix_ha) cannot reside on an NFS-imported share or on a shared disk and must not be configured this way."

But at the same page it says:
"HA requirements:
The shared_fs_disk layout for HA setups should provide for:
{{ trix_ha }}
{{ trix_home }}
{{ trix_shared }}
as an absolute minimum."

I am confused about trix_ha. Could you describe more please. Should we use DRBD only? Or are there any other mechanism to replicate trix_ha directory to passive controller, like trix_images directory replication.

I have defined trix_home and trix_shared for NFS and I did not defined trix_ha in shared_fs_disk section.

Hi TanerKaragol,

The restriction is mainly due to extended-attribute support, which may not be provided reliably by all NFS configurations. NFS can work if it is correctly configured end-to-end, but please ensure that all required TrinityX directories are consistently located on the same NFS.

We have seen issues with incomplete or unsuitable NFS configurations in the past; this is why the documentation recommends against using NFS for trix_ha.
