Subject: [PATCH] Incremental: add --export handling.
|
||||
|
||||
If --export is given with --incremental, then
|
||||
MD_DEVNAME
|
||||
is output which gives the name of the device (in /dev/md) that
|
||||
is the array (or container) that the device would be added to.
|
||||
Also
|
||||
MD_STARTED
|
||||
is set to one of
|
||||
no
|
||||
unsafe
|
||||
yes
|
||||
nothing
|
||||
|
||||
to indicate if the array was started. IF MD_STARTED=unsafe
|
||||
then it may be appropriate to run
|
||||
mdadm -R /dev/md/$MD_DEVNAME
|
||||
after a timeout to ensure newly degraded array are started.
|
||||
|
||||
If
|
||||
MD_FOREIGN=yes
|
||||
it might be appropriate to suppress this as the array is
|
||||
probably not critical.

|
||||
Subject: [PATCH] Incremental: improve support for "DEVICE" based restriction
|
||||
in mdadm.conf
|
||||
|
||||
--incremental currently fails if the device name passed does not
|
||||
textually match the names permitted by the DEVICE line in mdadm.conf.
|
||||
This is problematic when "mdadm -I" is run by udev as the name given
|
||||
can be a temp name.
|
||||
|
||||
This patch makes two improvements:
|
||||
1/ We generate a list of all existing devices that match the names
|
||||
in mdadm.conf, and allow rdev based matching
|
||||
2/ We allows extra aliases to be provided on the command line, and
|
||||
perform textual matching on those. This is particularly suitable
|
||||
for udev usages as ${DEVLINKS} can be provided even though the links
|
||||
make not yet be created.

|

Subject: [PATCH 1/2] Restructure assemble_container_content and improve
|
||||
messages.
|
||||
|
||||
We lose one level of indent, and now get told the difference between
|
||||
'not assemble because not safe' and 'not assembled because not enough
|
||||
devices'.
