Hello
I have got a Raid 5 with 4 160 GB Disk,
On of the Disks Failed because. But I know its OK I had this for some times.
A Restart solved The Problem.
But now Tried to raidhotremove the Drive and removed the wrong drive.
I just recongized the Problem after i raidhotadded itagain.
No the Raid tries to sync again.
Syslog gets flooded by the following
May 20 23:52:25 utgard kernel: md: syncing RAID array md0
May 20 23:52:25 utgard kernel: md: minimum _guaranteed_ reconstruction
speed: 1000 KB/sec/disc.
May 20 23:52:25 utgard kernel: md: using maximum available idle IO
bandwith (but not more than 200000 KB/sec) for reconstruction.
May 20 23:52:25 utgard kernel: md: using 128k window, over a total of
156288256 blocks.
May 20 23:52:25 utgard kernel: md: md0: sync done.
a cat /proc/mdstat gibes me different output

I know that all 4 Dives should be ok, how can i recover the Raid without
loosing data?
Does a restart help?
