[PVE-User] Problems with HP Smart Array P400 and ZFS

[Dreyer, Jan, SCM-IT]

Hi,

my configuration:
HP DL380 G5 with Smart Array P400
Proxmox VE 5.2-1
name: 4.4.128-1-pve #1 SMP PVE 4.4.128-111 (Wed, 23 May 2018 14:00:02 +0000) x86_64 GNU/Linux
This system is currently running ZFS filesystem version 5.

My problem: When trying to update to a higher kernel (I tried 4.10 and 4.15 series), the initrd is not able to detect the cciss devices, and as such not able to load the ZFS pools, including the root pool.
Falling back to kernel 4.4 doesn’t let me use the ZFS cache file system though. :-(

Any hints on how to detect the raid controller device in initrd?

Gruß / Regards

scsi: cciss: Drop obsolete driver
The hpsa driver now has support for all boards the cciss driver
used to support, so this patch removes the cciss driver and
make hpsa an alias to cciss.
Falling back to kernel 4.4 doesn’t let me use the ZFS cache file system though. :-(

Sounds a bit like:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1765105

Are your firmware versions all up to date?

I did not find related issues searching the LKML, Ubuntu's kernel devel or
related lists. (We very recently ported back a fix for hpsa but it was related
to clean shutdown, no changes for detection/bring up AFAICT).

AFAIR, the switch from cciss to hpsa also changed the way the 'disks'
were reported to the OS (cciss -> /dev/cciss/cXdYpZ, hpsa -> /dev/sdX).
Maybe your disks are present as /dev/sdX?

Hi.

First thanks for your (and Stoiko Ivanov’s) answers.

No, I’m pretty sure it’s not. As we don’t have an active support agreement for such old hardware anymore, we are not able to get the newest. I will try with the latest available Firmware Maintenance CD (May 2011), maybe it covers this already. If not, I think we have to either live with the error or replace / remove the hardware

Too bad, the newest (for me) available Firmware did not help. I will put this node out of the cluster and use it for a minikube installation 

Thanks anyway for your hints!
