Hi
I have a degraded array /dev/md2 ===================================================================== $ mdadm -D /dev/md2 /dev/md2: Version : 00.90.01 Creation Time : Thu Oct 6 20:31:57 2005 Raid Level : raid5 Array Size : 221953536 (211.67 GiB 227.28 GB) Device Size : 110976768 (105.84 GiB 113.64 GB) Raid Devices : 3 Total Devices : 2 Preferred Minor : 2 Persistence : Superblock is persistent

Number Major Minor RaidDevice State 0 0 0 -1 removed 1 8 21 1 active sync /dev/sdb5 2 8 37 2 active sync /dev/sdc5 UUID : 4c77d8a9:3952f00b:876ce47a:a65d5522 Events : 0.12152695 =====================================================================
I need to add the 3rd partition, so I open documentation http://www.centos.org/docs/4/html/rhel-isa-en-4/s1-storage-rhlspec.html#S2-S... (I know the RTFM ;-)
But in chapter 5.9.9.2. they want tool caled "raidhotadd"
What was my wonder when it is not included in CentOS 4.3 ===================================================================== # yum provides raidhotadd Searching Packages: Setting up repositories update 100% |=========================| 951 B 00:00 base 100% |=========================| 951 B 00:00 local 100% |=========================| 951 B 00:00 Reading repository metadata in from local files primary.xml.gz 100% |=========================| 71 kB 00:00 update : ################################################## 195/195 Added 0 new packages, deleted 2 old in 0.32 seconds Importing Additional filelist information for packages filelists.xml.gz 100% |=========================| 697 kB 00:00 update : ################################################## 195/195 Added 32 new packages, deleted 0 old in 2.51 seconds No Matches found =====================================================================
How can I repair the MD device?
