I have 3ware SE and have been pulling my hair out trying to fix this same problem. This is a must when maintaining a lot of machines using for instance a serial line console. Now, when you insert a different model replacement drive, simply create a partition with the exact same size as you noted down. There are two things I still need to try: Yes hpsa Yes Yes Yes? Don’t be affraid, just wait. Post as a guest Name.

The array is being verified since making these changes and while running these tests. As far as I know the cache cannot count in this case because the write is a long linear one.

Linux and Hardware RAID: an administrator’s summary

Just try buying a 20 Gb hard drive these days. As I said, my bus is bigger than 3warf all disks combined 2 Hotswap.

Software RAID lets me easily move disks to other controllers or even to other machines. I’ll go with software RAID then.

The Thelios machine look nice. What can be the cause of all this?

If it is, contact the manufacturer and, if they are worth anything, they will make it right for you. Some linux tools are available on a CD included with the controller. Details about individual drivers 3w-xxxx Hardware using this driver: I changed the StorSav profile to performance the other two options were protected and balanced. If the performance problem 3war gone, then it is definitely the controller. Now it performs similar to the mdadm RAID.

If the performance gains are going to be minimal, I would go software. You only linus the BBU for power outages. Then again, I’m writing much more than will ever fit in cache or in RAM when doing these tests. At the 3aare of aacraid section is the old information on tools available on Dell website, which may be useful for older distributions and controllers. I should be so lucky!

Like some bad sectors? No opensource tools for 3Ware cards currently exist. I’ve read your article quite a few times when investigating my own problems.

linux – 3ware card in RAID-5 configuration slow and causes load when writing – Server Fault

Wow, pretty big difference between ext3 and XFS here. Community Linux They will profit off your hard work Well, yeah. It works fine with and cards, as ,inux as with the series. It also handle unexpected output changes and reminders until the status is fine again. Or will I loose my whole array? Any advice in this area? Maybe better more correct way? This usually means that you need to resize and rebuild your entire array when you insert a different brand disk. This was not the case on at least one Dell PowerEdge machine.


However it use an awfull InstallShield installer which should be avoided in any case. But with hardware RAID you need the exact same model because block counts vary slightly from model to model and manufacturer to manufacturer.
