 |
|
compiled dist kernel using installkernel.
dracut was used to create the initrd file.
During boot hangs for some minutes.
Then a lot of messages by dracut.
Then after some time system enters the recovery mode.
the raid device entries are missing.
Looking at the .cofig of the new kernel all raid options are set.
So tried to use ugrd to create an initrd.
During generation following msg is posted:

Was able to create a working initrd with genkernel.
| Code: | | genkernel --mdadm initramfs |

linux_os2,
/dev/md126p8 is a partition on a software raid set. It should not belong to device mapper.
That looks like a bug in ugrd.

Can you share the output of "lsblk -f" please?
If you can use a paste service and run "ugrd -d", that would help, especially with the latest 9999 (git) version (v2). I think this may be happening because a that mdraid device with a partition is listed as the "slave" for another volume, which could possibly be a mistake.
