Topic: Going RAID

[Steve Davis]

On a similar subject, how about recovering from RAID-1 (mirroring) problems. Let's say a drive goes bad, and has to be removed from the mirror, leaving just one drive. Has anyone looked at how to restore that RAID-1 once a new drive has been obtained? The data is still there on the surviving drive, but I would rather not do a new install and then use Flexbackup to restore the system. Is there some routine that tells SME to remirror the drive from the good drive?

Recovery is always more interesting and critical to me than backups.

And as mentioned earlier and in other posts, if you value your data enough or if you are working with other people's data (ie. clients and customers), go hardware RAID with hotswap, etc.

Your customers will think you are a legend if a drive fails and all it takes to recover is to turn a key, remove a tray, swap drives, put back the tray and turn the key. All while the server continues to operate ! ZERO downtime. The hardware RAID automatically rebuilds.

Eg. The Accusys subsystems I sell :-

I agree 100%.

As to Graham's speed problem, I suspect it is the known Intel 845 chipset kernel compatibility issue. He can try tweaking BIOS settings, or (my recommendation) try 6.0beta3.
