Norco 4220 Case Hotswap problems

[Jerky_san]

I was wanting to know if anyone has ever successfully hot swapped a drive out of your norco case while the array was up and running? Like if one of your disks went bad and you swapped it out. I've done many tests in different scenarios and can't achieve this. I was wondering if I am simply doing something wrong..

The test system consist of 4 drives on the top row. 2 of the drives are in a raid 0, 1 is by itself ,and the other is for the test pull. If you pull the drive out and then put it back in.. All the arrays disappear and the raid 0 never returns.

I'm using a highpoint 4320 card with a chenbro sas expander(if connected directly it still does it). The powersupply is a 850w Rosewill. I'm currently using the UEK version of the sas expander to do these tests. ANY suggestions are welcome..

As far as I know, that behaviour is tied to the OS and array setup. I'm also curious about this because I hope to build a monster array in a 4220 in the coming future, and was planning on using Ubuntu with RAID 6.

In my tests with Ubuntu and RAID 5, I was able to remove a (virtual) partition and add it in successfully. The file format was XFS and I declared the drive as "dead" before pulling it. You might have to do the same, though I'm not even sure if RAID 0 or 1 supports the hot swap you're looking at.

Are you sure you are pulling the right drive, and not one of the RAIDed disks?

Yes, I'm very sure.. The reason I can be so sure is because the raid 0 are 2 1tb green drives, the one that isn't in the array but isn't being pulled/plugged is a maxtor sata, and the drive that is being pulled/plugged is a seagate drive. I've tried this on a promise card and this adaptec with no luck of hotswaps. I've not tried it on my adaptec card but I'm guessing I'll get the same result..
