Title: RAID monitoring
Post by: benja on July 22, 2002, 12:02:43 PM

Hi,

I Install SME 5.5 with soft mirroring / SCSI. Everything is fine. I would like to know how i can monitor my RAID system so that i can be noticed when a failure occur on one of the two disk. Is there anything to do to send an email (for exemple, to the admin account) in such a situation.

Thanks,
benja

Hi,

Following the last post, I install Raidmonitor. Thanks Jon, it's exactly what i was looking for. But i noticed something very strange in my system when i try to test the raid system : the two boot partitions are on the same disk !!!

more detail :
md0 is /boot on sda5 and sda6
md1 is / on sda7 and sdb5
md2 is swap on sda1 and sdb1

My server is an IBM Netfinity 3500 whith an Adaptec SCSI  chip 7895. The two disk are not the same : one IBM DDRS-34560D (4,1 Go) and one DCAS-34330W
(4,3 Go). During the install, everything seems to be OK.

Is there anything else to do during the install process ?

Thanks

Benja,

Below is my raid config

md2 : active raid1 hdc1[1] hda1[0] 264960 blocks [2/2] [UU]
md0 : active raid1 hdc5[1] hda5[0] 15936 blocks [2/2] [UU]
md1 : active raid1 hdc6[1] hda6[0] 19269824 blocks [2/2] [UU]
 
Yours looks very strange. Did you use the software raid option or use hardware raid.

I use software raid. Someone told me that the disk should be same size or capacity. This is probably the problem. I will try to find another HD. If I couldn't, il will disable mirroring.

Thanks,
