Hello everybody, Caspar Smit wrote, on 09-04-10 17:52: > I'm still having troubles with SATA disks using the mvsas driver. > Maybe you read my previous posts about the WD disks. I would like to confirm a lot of the issues. I saw the emails from Caspar Smits passing by the last few days. I got a bunch of the below storage controllers for testing, and I am not yet able to actually use them stable. My major killer issue is that the I am unable to load my Linux kernel and root file system from the SATA disks attached to the controller. Grub works fine and starts the initrd, but then mdadm fails because the hard disk are not found fast enough by the Linux kernel and I see "HDIO_GET_IDENTITY failed for" messages for all the connected hard drives. Some system and hardware information. # cat /proc/version Linux version 2.6.32-4-amd64 (Debian 2.6.32-11) (maks@xxxxxxxxxx) (gcc version 4.3.4 (Debian 4.3.4-8) ) #1 SMP Tue Apr 6 08:21:34 UTC 2010 # lspci -nn | grep SCSI 02:00.0 SCSI storage controller [0100]: Marvell Technology Group Ltd.

I also noticed that some of the attached drives worked fine with: smartctl -d sat -H /dev/sda but some of the identical drives did not worked and needed the -T permissive options... BTW I also have some 04:06.0 SCSI storage controller [0100]: Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X Controller [11ab:6081] (rev 09) hardware and those use the sata_mv module. This system works stable and no errors during boot. However the SATA interfaces are very slow here because of the PCI bus limitation of the hardware. The MV88SX6081 card also boots very vast to grub compared with the MV64460/64461/64462 card. Is there something that can be done about this? I would really like the usability of the MV88SX6081 card but with the full speed of the SATA links of the PCI-E enabled mvsas cards. For those intressted I use them with mdadm raid1 with two device pairs, with lvm2 with striping and ext4 file systems. The root file system is also on this raid,lvm,ext4 layout.
