Hello list.
I just updated my ubuntu system. The update provided a new kernel image also.
Here is what I got back:
update-initramfs: Generating /boot/initrd.img-3.13.0-49-generic
W: mdadm: the array /dev/md/kvm15:10 with UUID
c4540426:9c668fe2:479513f2:42d233b4
W: mdadm: is currently active, but it is not listed in mdadm.conf. if
W: mdadm: it is needed for boot, then YOUR SYSTEM IS NOW UNBOOTABLE!
W: mdadm: please inspect the output of /usr/share/mdadm/mkconf, compare
W: mdadm: it to /etc/mdadm/mdadm.conf, and make the necessary changes.
Is ist OK to just edit mdadm.conf and replace
ARRAY /dev/md/0 metadata=1.2 UUID=75079a2f:acb8c475:85f8ca43:0ad85c4c
name=kvm15:0
with:
ARRAY /dev/md/127 metadata=1.2 UUID=c4540426:9c668fe2:479513f2:42d233b4
name=kvm15:10
Or is there any other action recommended?
Thank you for your help.
Stefan
