[merging]
The HBA the drives are attached to has no configuration that I’m aware of. We would have had to accidentally change 23 of them ☺
Thanks,

- posting to the list in the hopes of getting more eyeballs on it.
We have a cluster of 23 HP DL380p Gen8 hosts running Kafka. Basic specs:
2x E5-2650 128 GB RAM 12 x 4 TB 7200 RPM SATA drives connected to an HP H220 HBA Dual port 10 GB NIC
The drives are configured as one large RAID-10 volume with mdadm, filesystem is XFS. The OS is not installed on the drive - we PXE boot a CentOS image we've built with minimal packages installed, and do the OS configuration via puppet. Originally, the hosts were running CentOS 6.5, with Kafka 0.8.1, without issue. We recently upgraded to CentOS 7.2 and Kafka 0.9, and that's when the trouble started.
<SNIP> One more stupid question: could the configuration of the card for how the drives are accessed been accidentally changed?
