mdadm ( 2xSATA ) RAID 1, Fedora Core 5 - Not keeping system running
Posted on 2006-05-29
I've created a RAID1 with 3 partitions on it, with 2 SATA HD's 250Gig.
[root@localhost /]# cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sda1 sdb1
104320 blocks [2/2] [UU]
md2 : active raid1 sdb2 sda2
1028096 blocks [2/2] [UU]
md0 : active raid1 sda3 sdb3
243063360 blocks [2/2] [UU]
unused devices: <none>
To what I can tell they seemed fine, but when I unplug one of the hard drives (SATA) to simulate a drive failure, the whole system stops (freezes). And it only comes back when I plug it back in. Checked the RAID Status and is fine.
My understanding of a RAID 1 is that because the two Hard drives are Mirrored no matter which hard drive I pull the System should still be operational.
All I want is Hard Drive redundancy in the case of a drive failure.
Thank you in advance.
