Bug#415336: mdadm: doWhatINeed argument to init script

[Eduard Bloch]

reopen 415336
thanks

You have pretty short timeouts...

See attachments for an extended version of your script, allowing to
force the update of the array data. Because currently it sucks, it does
not start the arrays on Knoppix because there is a dummy config file
already, and it does not tell you what is going wrong :-(

A manpage is also there.

Eduard.
