I am trying to document the mdadm-4.2 installation procedures for our book, https://www.linuxfromscratch.org/blfs/view/svn/postlfs/mdadm.html For testing, I am doing a simple: make sudo ./test --keep-going --logdir=test-logs --save-logs But I get failures for about half the tests. Digging in a bit I just ran: sudo ./test --tests=00raid0 --logdir=test-logs This is the first test that fails. With some hacking, it appears that the first portion of this test that fails is: mdadm -CR $md0 -e0.90 -l0 -n4 $dev0 $dev1 $dev2 $dev3 This resolves to mdadm -CR /dev/md0 -e0.90 -l0 -n4 /dev/loop0 /dev/loop1 /dev/loop2 /dev/loop3 There is not a lot of error output in the test, so I manually ran: dd if=/dev/zero of=/tmp/mdtest0 count=20000 bs=1K losetup /dev/loop0 /tmp/mdtest0 For /dev/loop[0123] Then I ran mdadm -CR /dev/md0 -e0.90 -l0 -n4 /dev/loop0 /dev/loop1 /dev/loop2 /dev/loop3 mdadm: 0.90 metadata does not support layouts for RAID0 My question is whether the regression tests in the tarball are valid for mdadm-4.2? -- Bruce Dubbs linuxfromscratch.org Note: The kernel is version 5.15.12.
