Package: mdadm Version: 2.5.6-5 Severity: minor Looking at the manpage, it seems to me that the 'standard' device names are only needed for --auto=yes:
DEVICE NAMES
While entries in the /dev directory can have any format you
like, mdadm has an understanding of ’standard’ formats which it
uses to guide its behaviour when creating device files via the
--auto option.
This seems to suggest that --auto requires them, irrespective of
the argument passed to --auto. However,
-a, --auto{=no,yes,md,mdp,part,p}{NN}
[...] "md" causes a non-partition‐ able array to be used. "mdp",
"part" or "p" causes a partition‐ able array (2.6 and later) to
be used. "yes" requires the named md device to have a ’standard’
format [...]
This seems to suggest that only "yes" requires the 'standard'
format.
Yet apparently, mdadm gets confused if a standard device name is
used together with an explicit --auto argument:
piper:~# mdadm -Cl1 -n2 -ap /dev/md_d99 /dev/sd[fh]1
mdadm: array /dev/md_d99 started.
piper:~# ls /dev/md_d99*
/dev/md_d99 /dev/md_d99p1 /dev/md_d99p2 /dev/md_d99p3 /dev/md_d99p4
piper:~# mdadm -S /dev/md_d99
mdadm: stopped /dev/md_d99
piper:~# mdadm -Aap /dev/my-raid-array /dev/sd[fh]1
mdadm: /dev/my-raid-array has been started with 2 drives.
piper:~# ls /dev/my-raid-array*
/dev/my-raid-array /dev/my-raid-array2 /dev/my-raid-array4
/dev/my-raid-array1 /dev/my-raid-array3
mdadm: stopped /dev/my-raid-array
piper:~# mdadm -Aap /dev/md99 /dev/sd[fh]1
mdadm: /dev/md99 has been started with 2 drives.
piper:~# ls /dev/md99*
/dev/md99
piper:~# mdadm -S /dev/md99
mdadm: stopped /dev/md99
So if I use /dev/md99, which is a standard name for
non-partitionable arrays, mdadm disregards the -ap argument.
It's arguable whether this is a bug; if it is not, maybe the
documentation could be clarified?
