Hi [EMAIL PROTECTED]
After careful thinking, I started reading the manpages again, more
exactly raidctl(8) and raid(4). Of course, I was not paying attention
the first 5 times i've read them ( stupid me ).
In raidctl (8) it states clearly the special circumstances for setting
up a raid array in degraded mode.
"Configuration(using *-C* and *-I* /12345/ as above) proceeds normally,
but initialization of the RAID set will have to wait until all physical
components are present. After configuration, this set can be used
normally, but will be operating in degraded mode. Once a second physical
component is obtained, it can be hot-added, the existing data mirrored,
and normal operation resumed."
So there's where i've made the mistake. After configuring the degraded
raid array i was initializing him
( raidctl -vi raid0 ).That's why after adding the "real" partition as
spare , doing a reconstruction of component0 and parity re-write,after
reboot component0 kept failing.
Thank's againg to all and sorry again for the unnecessary bnoiseb.
