Nodes constantly fencing for no obvious reason

[Pintjes]

Using ZFS with consumer SSDs is often probematic on it's own - due to the CoW nature of ZFS it writes a lot more than non-CoW filesystems and consumer SSDs can get really slow in these cases, even slower than spinning rust.

I am looking to buy entreprise SSDs (717968-001 to be specific) and I will be looking to swap out the p420i with a 9207-8i to run it in IT mode.

Can we keep this thread open for now to see if the new LSI changes things?
Thanks for all the time and effort!

We don't generally close threads here, so no worries

Would be interesting indeed if it's caused by the system instability due to hung I/O kernel tasks.

Update: after switching the LSI to a true HBA card (was plug and play) the issues seem to be solved.

Thanks for helping!
