RAID Woes - What is going on?!
Lo all.
In order to preserve my flowing locks please can you help with the following conundrum:
Some time ago I decided that, instead of wailing terribly in the event of a hard disk failure, I'd buy some preventative hardware.
Volume of data ruled out DVD backup and tape drives are still way too expensive for home use. Also at the time external disk arrays on esata, firewire or gigabit were few and big bucks.
I settled for running RAID on our two key home machines to overcome the most likely single disk failure nightmare. I also chose to buy long warranty hard drives for additional piece-of-mind (Maxline III's are 24/7 5yr warranty).
In my siggie you will see two PC's listed.
PC 1 is running ok after a rebuild hiccup or two. It's problem was that the onboard SI3114 RAID controller was in its infancy and although it was touted to support RAID5 this flavour does not.
After much hassle I caved in and am now happily running RAID10.
PC 2 however is suffering big time and I really need some pointers.
This machine is used for video editing. It has dual on-board RAID controllers, an SI3114 which is RAID5 capable and the generic NVRAID controller.
It is configured with 4 disks on the SI3114 in RAID5 and 2 on the NVRAID in RAID1 (RAID0 originally but too unstable).
The problem is that the machine keeps forgetting its disks. The RAID5 will run for less than 12hrs before it throws its toys out the pram and demands a rebuild. What was a RAID0 was also terrible at this and since moving to RAID1 has been more reliable but I guess it does the same every fortnight or so.
It could be the disks but if they were genuine failures then the RAID arrays wouldn't rebuild successfully.
If could be a lack of power but even if all the disks pulled 40-50W peak isn't there enough juice to cope?
Is the motherboard just badly designed and can't keep things together when asked to muck about with six disks?
In short what is going on?! :confused:
Plz help!
