So I have a server with 5 1tb hard drives that have been working in a RAID 5 configuration for about 8 months now. Everything is working fine, I am just wanting to add three more hard drives to the array (grow it). Well I went to check the status on the current RAID 5 before I get ready to add the other three hard drives to it and it looks like there are only 4 hard drives working for some reason. Here is details from mdadm:
harold@server:~$ sudo mdadm --detail /dev/md0
/dev/md0:
Version : 00.90.03
Creation Time : Mon Feb 11 16:48:31 2008
Raid Level : raid5
Array Size : 3907039744 (3726.04 GiB 4000.81 GB)
Used Dev Size : 976759936 (931.51 GiB 1000.20 GB)
Raid Devices : 5
Total Devices : 4
Preferred Minor : 0
Persistence : Superblock is persistent
Update Time : Sun Jul 13 23:12:12 2008
State : clean, degraded
Active Devices : 4
Working Devices : 4
Failed Devices : 0
Spare Devices : 0
Layout : left-symmetric
Chunk Size : 64K
UUID : 72fa18f5:bf5d1a62:31a05266:02bffc2c
Events : 0.54
Number Major Minor RaidDevice State
0 8 113 0 active sync /dev/sdh1
1 0 0 1 removed
2 8 33 2 active sync /dev/sdc1
3 8 49 3 active sync /dev/sdd1
4 8 65 4 active sync /dev/sde1
I dont know why I am getting this error:
1 0 0 1 removed
If I go into the partition editor I can see that I have all eight hard drives hooked up to the computer and running, but I just don't understand this. I am not the greatest with linux but am getting be decent, so take it easy on me! Thanks!
