Comments

[Simppa Akaslompolo]

After migrating from RHEL 9.4 to RHEL 9.5, we have had 1-2% failure rate per hour of compute nodes in our cluster. I cannot pinpoint it to lustre, as I have not yet managed to get even a kernel panic out from the instantly freezing nodes. I'm reporting here in hope of someone else having similar experience. The behaviour reminds me of freezes I saw without the patch to LU-17696, but occurring much more rarely.

I will next concentrate on getting more information how exactly the nodes die.
