[gpfsug-discuss] forcibly panic stripegroup everywhere?

[Aaron Knister]

This is going to sound like a ridiculous request, but, is there a way to 
cause a filesystem to panic everywhere in one "swell foop"? I'm assuming 
the answer will come with an appropriate disclaimer of "don't ever do 
this, we don't support it, it might eat your data, summon cthulu, etc.". 
I swear I've seen the fs manager initiate this type of operation before.

I can seem to do it on a per-node basis with "mmfsadm test panic <fs> 
<error code>" but if I do that over all 1k nodes in my test cluster at 
once it results in about 45 minutes of almost total deadlock while each 
panic is processed by the fs manager.
