Hello Walt,

thanks for your reply, I see that

https://github.com/waltligon/orangefs

is the official repository.

Can you point me to the branches (if not master) for V3 ?

Thanks in advance

Kind regards

Federico

This was useful for a people with certain problems.

OFS Version 3 has full configurable redundancy for Trove objects -
both data and metadata.  Of course V3 is still being written and is
somewhat stalled since covid19.

Hello,

is there some mirroring scheme available in OrangeFS 2.9.8 for
redundancy ?

Apart from the HA obtained via heartbeat.

I see in the code the files "create-immutable-copies.sm" and
"mirror.sm".

Thanks in advance

Kind regards
