So is there any compelling reason with RAID1 not to use type 0xFD, and instead of the above, create using the following?:
mdadm -Cv /dev/md9 -e 0.90 --homehost=fi965 -l 1 -n /dev/sdb17 missing
There is no home host in 0.90 metadata (it does not have place to store it).
That inconsistent with my understanding of the homehost section of the man page, which indicates it's simply stored differently with 0.90.
Is there material advantage in 1.2 metadata other than offering arbitrary naming? It seems to me possibly advantageous to use 0.90 unless an arbitrary name is desired.
Why do you bother in the first place? Use whatever is default in mdadm.
In part, because when I look at the result in the future I'm unlikely to have any idea how to figure out what the defaults were at create time. It won't be in the YaST2 logs, but how it got to be will be found in .bash_history at least for a while. -- "The wise are known for their understanding, and pleasant words are persuasive."
