Hi,
I already asked this question on serverfault. But I guess here is a better place.
I have a very ancient hardware with a MPTSAS controller. I use this for TripleO deployment testing. With the release of Ussuri which is running CentOS8, I can no longer provision my overcloud nodes as the MPTSAS driver has been removed in CentOS8:
https://www.reddit.com/r/CentOS/comments/d93unk/centos8_and_removal_mpt2sas_...
I managed to include the driver provided from ELrepo in the introspection image but It is not loaded automatically:
All commands are run as user "stack".
Extract the introspection image:
cd ~ mkdir imagesnew cd imagesnew tar xvf ../ironic-python-agent.tar mkdir ~/ipa-tmp cd ~/ipa-tmp /usr/lib/dracut/skipcpio ~/imagesnew/ironic-python-agent.initramfs | zcat | cpio -ivd | pax -r
Extract the contents of the mptsas driver rpm:
rpm2cpio ~/kmod-mptsas-3.04.20-3.el8_2.elrepo.x86_64.rpm | pax -r
Put the kernel module in the right places. To figure out where the module has to reside I installed the rpm on a already deployed node and used find to locate it.
xz -c ./usr/lib/modules/4.18.0-193.el8.x86_64/extra/mptsas/mptsas.ko > ./usr/lib/modules/4.18.0-193.6.3.el8_2.x86_64/kernel/drivers/message/fusion/mptsas.ko.xz mkdir ./usr/lib/modules/4.18.0-193.6.3.el8_2.x86_64/weak-updates/mptsas sudo ln -sf /lib/modules/4.18.0-193.el8.x86_64/extra/mptsas/mptsas.ko lib/modules/4.18.0-193.6.3.el8_2.x86_64/weak-updates/mptsas.ko sudo chown root . -R find . 2>/dev/null | sudo cpio --quiet -c -o | gzip -8 > ~/images/ironic-python-agent.initramfs
Upload the new image
cd ~/images openstack overcloud image upload --update-existing --image-path /home/stack/images/
Now when I start the introspection and ssh into the host I see no disks:
[root@localhost ~]# fdisk -l [root@localhost ~]# lsmod | grep mptsas
Once i manually load the driver, I can see the disks:
[root@localhost ~]# modprobe mptsas [root@localhost ~]# lsmod | grep mptsas mptsas 69632 0 mptscsih 45056 1 mptsas mptbase 98304 2 mptsas,mptscsih scsi_transport_sas 45056 1 mptsas [root@localhost ~]# fdisk -l Disk /dev/sda: 67.1 GiB, 71999422464 bytes, 140623872 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
But how can I make it so that it will automatically load on boot?
Best Regards,
Oliver
