FOAK: Fibrenetix X3i RAID

The Fibrenetix X3i RAID connected to our Beowulf has just gone tits up
in a bad way and the manual they make available online doesn't
correspond to the machine they sold us (which is now out of
warranty). Does anyone have a clue how to remove a disk from this
machine via its menu? If you say angle grinder I'll give you my turn
to a pillar of shit look.

 

For what its worth I would recommend you only get advice from an asbolute
expert in this area, for risk of loss of data.

I don't know much about RAID but I do know that some types of raid are
configured in different ways, and depending on your raid config (better say
raid 5 than 0 for fault tolerance) you may be able to just bang another disk
in and go. You may already know this.

Don't know FA specific to your RAID so I would refer to the support pages
somewhere or hopefully someone will be along soon. The best thing to do in
the meanwhile, is nothing.

 

The man on the helpline (the cluster supplier, not the RAID) said take
the duff disk(s) out, rebuild and hope I don't lose more than 10% of
the data. It is RAID 5 so it should be able to recover what's there.

 

Back it all up. But you've done that already haven't you? Now you can
pull disks out and replace them. If it rebuilds you won't lose any data
and most RAID systems worth spending money on are designed to rebuild
automatically,

 

I'm on the edge of my seat here - what happened next?
