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.
