Raid problems?? DMRAID

metalenkist · 11-22-2007, 04:02 PM

Hey all, I'm in a little dillema (is that a good english word?) about my raid 10 system. I'm not sure if a harddisk is failing is not.

Code:

leonweemen:/ # fdisk -l

but when I do

Code:

leonweemen:/ # dmraid -r
/dev/hda: hpt45x, "hpt45x_dbgjdcidg-0", stripe, ok, 312581760 sectors, data@ 0
/dev/hdc: hpt45x, "hpt45x_dbgjdcidg-1", stripe, ok, 312581760 sectors, data@ 0
/dev/hde: hpt45x, "hpt45x_dbgjdcidg-0", stripe, ok, 312581760 sectors, data@ 0
/dev/hdg: hpt45x, "hpt45x_dbgjdcidg-1", stripe, ok, 312581760 sectors, data@ 0

OR

Code:

leonweemen:/ # dmraid -s
*** Active Superset
name   : hpt45x_dbgjdcidg
size   : 625163520
stride : 128
type   : raid10
status : ok
subsets: 2
devs   : 4
spares : 0

It just says ok. Is there a way to make it sure if it's ok??. I thought that dmraid had this option to check the raid system on it's state.

It's been a week, so I'll jump in & see if I can at least clarify your problem.

1st, a couple of tips on English:
It's "dilemma"
It's "its", the way you used it -- "it's" == "it is", "its" == "belonging to it", just like "his", "hers", & "theirs".

As for your Q, you neither give us any description on your RAID array, nor a reason why you don't trust the output of dmraid.

I hope this helps a little, unfortunately my only currently running RAID array is an old* software RAID 1, so I don't think I can help much more than this.

*old == on my MEPIS 3.3.2 box which doesn't & can't have dmraid.
