I have the latest RHEL5 openvz kernel (http://wiki.openvz.org/Download/kernel/rhel5/028stab069.6) and for some reason it is recognizing my sata hard drives as IDE. This is killing my performance on the server.
If I switch over to the default kernel is recognizes the hd's as Sata's.
Here are some hdparm tests using the openvz kernel, and then the default kernel:
--------------------------------------------------------
[root@openvz400 ~]# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 12 MB in 3.40 seconds =
3.53 MB/sec
--------------------------------------------------------
Then when I switched to a default kernel... ( so disk are displaying in SDA) and gave me these results:
--------------------------------------------------------
hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 248 MB in 3.01 seconds =
82.35 MB/sec
--------------------------------------------------------
Any ideas how to fix this hd issue?
