Hi,

we are using the stock xen 2.6.18 kernel (build form the xen sources).
Are there others drivers than in the stock kernel ones available?

I think this is the relevant dmsg output for the raid controller:

scsi0 : LSI Logic SAS based MegaRAID driver

SCSI device sda: 2927099904 512-byte hdwr sectors (1498675 MB)
sda: Write Protect is off
sda: Mode Sense: 1f 00 00 08
SCSI device sda: drive cache: write back

sda: Mode Sense: 1f 00 00 08
SCSI device sda: drive cache: write back
 sda: sda1 sda2
sd 0:2:0:0: Attached scsi disk sda

But what conserns me now is that on all our servers, I just found outthat the state of our array says "degraded" and "30% rebuild rate".I just opened a support ticket with dell about this, but has anyone anidea what this could be?


Regards,

        Philipp

Hi,
we are using dell poweredge 2950 servers with a "PERC 6/iIntegrated" hardware raid controller.
Lg Philipp
How are the read-ahead and write-cache settings set on the PERC6/iand which/whose RAID drivers are you using under dom0 (output fromdmesg, etc.)
Cheers,
