Hi All,

Is it possible to replace the failed disk in one of my server with another disk (which contains data from not so important server) on the fly without reboot or down time ?

thanks

Yes - if the disks are suitable for the system and are hot-swap, then any data on the drive will get replaced with the information that used to live on the old failed HDD.  No reboot needed.

ah great, I was afraid if the other way around is happening (data from the old spare server hard drive gets replicated to the current working server in the production).

yes I do have the exact model but it is of course not yet formatted.

What RAID level is configured on the server with the failed disk?

'What RAID level is configured on the server with the failed disk?' RAID-1 s it is only equipped with just 2x 76 GB 10k RPM SAS disk.

As Alan said, as long as you put the replacement in hot the controller will ignore the metadata on it.

"hot" controller ?

Can I assume that with RAID - 1 if one of the disk fails, then any disk inserted into it will then be autoformatted and then the data recalculated while the drive is online ?

Hot disk, not hot controller. If you add the disk hot (i.e. with the server on) the controller will know that it is to be overwritten and will rebuild the mirror automatically.

If you replace it cold the controller will throw an error because it doesn't know which disk to overwrite.

Sorry - tied up moving a customer to new premises.

Okay - so you should be all set to just pull the failed drive and plug in the replacement and it will get on with the rebuild.
