[Evms-devel] add spare to a degraded raid5

[Samuel V. <sam...@gm...>]

Dear list,

I'm looking for a new way to store my (precious) data in a cheap and
effective way... After expermenting with mdadm and raidreconf, i
discovered evms. 
I immediately started testing it. 
To test i only have one disk available (an old maxtor IDE 30GB disk).

So i created 6 segments on the drive, each of them 1GB.
After that i created a raid 5 array > Actions  > Create > Region > MD
RAID 4/5 Region Manager
I selected 5 segments on my drive (hdc[5-9]) and the raid5 device was
created
Then i created a volume on the raid5 array:
Actions > Create > EVMS Volume
Then i formatted this volume with ext3.

Then i started testing the expansion option. I added a segment and let
the volume expand all accross it. 
Works like a charm... (looks like we got a winner....)

But then this...
I wanted to test how i can recover from a disk error...
so...
I quit evmsgui
dd if=/dev/zero of=/dev/hdc6

Start evmsgui again
I get a nice error : 
Aug 30 15:37:57  MDRaid5RegMgr: RAID5 array md/md0 is missing the
member  with RAID index 1.  The array is running in degrade mode.

Aug 30 15:37:57  MDRaid5RegMgr: Region md/md0 is currently in degraded
mode.  To bring it back to normal state, add 1 new spare device to
replace the faulty or missing device

Which is all nice and dandy... But there is nowhere an option to add a
spare device to my raid array.

I have plenty of unpartitioned space on that disk and i have 2
available segments too....

So i'm a bit wondering what to do now... Obviously i want to fix my
array by adding a spare device but where and how?

thnx,
S.
