Currently, it's possible that draid vdev asize would decrease
after disks replacements when the disk size is a little less than
all other disks in the pool. In such situations, import would
fail on this check in vdev_open():
/*
* Make sure the allocatable size hasn't shrunk too much.
*/
if (asize < vd->vdev_min_asize) {
vdev_set_state(vd, B_TRUE, VDEV_STATE_CANT_OPEN,
VDEV_AUX_BAD_LABEL);
return (SET_ERROR(EINVAL));
}
Solution: fix vdev_draid_min_asize() so that it would round up
the required minimal disk capacity to the VDEV_DRAID_ROWHEIGHT.
This would refuse replacements with the disks whose size is less
than minimally required to avoid draid asize decrement.
Note: we also use VDEV_DRAID_ROWHEIGHT in vdev_draid_open() when
calculating asize, and thats why we need to round up min_size at
vdev_draid_min_asize() to avoid asize drops.

Supported Kernels and Distributions
Linux
Given the wide variety of Linux environments, we prioritize development and testing on stable, supported kernels and distributions.
Kernel (kernel.org)
All longterm kernels from kernel.org are supported. stable kernels are usually supported in the next OpenZFS release.
Supported longterm kernels: 6.18, 6.12, 6.6, 6.1, 5.15, 5.10.
Red Hat Enterprise Linux (RHEL)
All RHEL (and compatible systems: AlmaLinux OS, Rocky Linux, etc) on the full or maintenance support tracks are supported.
Supported RHEL releases: 8.10, 9.7, 10.1.
Ubuntu
All Ubuntu LTS releases are supported.
Supported Ubuntu releases: 24.04 “Noble”, 22.04 “Jammy”.
Debian
All Debian stable and LTS releases are supported.
Supported Debian releases: 13 “Trixie”, 12 “Bookworm”, 11 “Bullseye”.
Other Distributions
Generally, if a distribution is following an LTS kernel, it should work well with OpenZFS.
FreeBSD
All FreeBSD releases receiving security support are supported by OpenZFS.
Supported FreeBSD releases: 15.0, 14.3, 13.5.
