Package dependencies

  1. LVM2 is installed.
  2. For HA features, kernel-devel shall be installed and has a compatible version with the current kernel.
  3. For VolumeResize features, a tool to resize the filesystem is required. By default, xfs is used as the volume filesystem. Therefore, you need to install xfs_growfs on the host.
CentOS/RHEL, Rocky and Kylin
$ yum install -y lvm2
$ yum install -y kernel-devel-$(uname -r)
$ yum install -y xfsprogs
$ apt-get install -y lvm2
$ apt-get install -y linux-headers-$(uname -r)
$ apt-get install -y xfsprogs

Secure Boot

The HA feature does not support Secure Boot currently. Make sure Secure Boot is disabled

$ mokutil --sb-state
SecureBoot disabled

$ dmesg | grep secureboot
[ 0.000000] secureboot: Secure boot disabled

Data disks

HwameiStor supports HDD, SSD, and NVMe.

For test, each host must have at least one unused drive with a minimal size of 10GiB.

For production, it is recommended to have at least one unused drive, protected by RAID1 or RAID5/6, with a minimal size of 200GiB.


For production, it is recommended to have a redundant 10Giga TCP/IP network, if the HA feature is enabled.
