add support of lvm-localpv to run in other distros of linux
Describe the problem/challenge you have
Used RHEL centos-7 to provision volumes, when I deployed the
application pod it stuck in ContainerCreating state due to mounting issues.
Mount failed: exit status 32
Mounting command: mount
Mounting arguments: -t xfs -o defaults /dev/lvmvg/pvc-a77bc831-76ec-40b1-80ed-8cdcaa7187d1 /var/lib/kubelet/pods/bcb76f32-d9ce-48b5-b255-dfa31147f5a6/volumes/kubernetes.io~csi/pvc-a77bc831-76ec-40b1-80ed-8cdcaa7187d1/mount
Output: mount: /var/lib/kubelet/pods/bcb76f32-d9ce-48b5-b255-dfa31147f5a6/volumes/kubernetes.io~csi/pvc-a77bc831-76ec-40b1-80ed-8cdcaa7187d1/mount: wrong fs type, bad option, bad superblock on /dev/mapper/lvmvg-pvc--a77bc831--76ec--40b1--80ed--8cdcaa7187d1, missing codepage or helper program, or other error.
Describe the solution you'd like: It is good to add support of lvm-local PV on different linux distros.
Anything else you would like to add: No
Environment:
- LVM Driver version: lvm2
- Kubernetes version (use
kubectl version): - Kubernetes installer & version:
- Cloud provider or hardware configuration:
- OS (e.g. from
/etc/os-release):
[root@hzcmaster0 openebs-example]# cat /etc/os-release NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31"
meet the same question！
Using EL8 (Centos 8) there is no issue whatsoever in using lvm-localpv. The deployment is straightforward. The PVC/PV lifecycle works as expected, and LVM logical-volume devices are created/mounted/removed as supposed. All good!
Now, the README.md limits the supported system config to Ubuntu. Will CentOS 8 / RHEL 8 be considered as a supported target platform?
After digging into the issue found the root cause of not being able to mount xfs formatted LVM volumes... It was happening due to incompatibility between xfs version inside the csi-container and xfs version at host machine... To address this issue we have to format the xfs with following option mkfs.xfs -m reflink=0 <device_name>
This is a duplicate of #135. It's because mount_utils doesn't force format xfs filesystems.
Closing this one as there are three issues open already for same problem, mentioned in previous comments.
