mdadm: Value "nas:md0" cannot be set as devname

1st Official Post

    Hello!


    Recently I have upgraded my OMV from 7 to 8. All seems to work well but after turning the NAS on I receive the following notification to mail:

    Quote

    /etc/cron.daily/openmediavault-mdadm:

    mdadm: NewArray event detected on md device /dev/md0

    mdadm: Value "nas:md0" cannot be set as devname. Reason: Not POSIX compatible. Value ignored.

    My mdadm.conf looks like this:

    Code
    DEVICE partitions
# auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes
# automatically tag new arrays as belonging to the local system
HOMEHOST <system>
# instruct the monitoring daemon where to send mail alerts
MAILADDR my@email.com
MAILFROM root
# definitions of existing MD arrays
ARRAY /dev/md/nas:md0 metadata=1.2 name=nas:md0 UUID=b0b7703d:4da40b26:28176a4e:a72b0f7a

    Could you please tell me how to fix this issue?

    You hit a Debian 13 change. Device names must be POSIX compliant, and a : is breaking this rule. To fix that, modify /etc/mdadm/mdadm.conf:

    Code
    ARRAY /dev/md/nas:md0 metadata=1.2 name=nas:md0 UUID=...

    to

    Code
    ARRAY /dev/md0 metadata=1.2 UUID=...

    and run

    Bash
    # omv-salt deploy run initramfs

    After that you should reboot the system.
