aacraid write through cache into write back cache

[Samuel Díaz García]

I have an Adaptec 2410SA raid controller with RAID 1 configured on it.
The system is an AMD ATHLON 1800 CPU. With FC4 updated distro.

The system is working fine, but TOOOOOOOOOOOOO SLOOOOOWWWWWWWWWW.

Taking a view into startup messages I can see:

sda: got wrong page
sda: assuming drive cache: write through

In dmesg:

...
AAC0: kernel 4.1-0[5934]
AAC0: monitor 4.1-0[5934]
AAC0: bios 4.1-0[5934]
AAC0: serial bab115
scsi0 : aacraid
   Vendor: ADAPTEC   Model: UNO               Rev: V1.0
   Type:   Direct-Access                      ANSI SCSI revision: 02
SCSI device sda: 156247808 512-byte hdwr sectors (79999 MB)
sda: Write Protect is off
sda: Mode Sense: 03 00 00 00
sda: got wrong page
sda: assuming drive cache: write through
SCSI device sda: 156247808 512-byte hdwr sectors (79999 MB)
sda: Write Protect is off
sda: Mode Sense: 03 00 00 00
sda: got wrong page
sda: assuming drive cache: write through
  sda: sda1 sda2 sda3
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0
...

I think changing write through into write back cache will solve the problem.

The controller utility was used to configure all caches in the drivers.

Any help about this topic?

Thanks

[Samuel Díaz García]

Any kernel parameter or module parameters?
Any idea in how to solve the problem?

Hi,
Happy new year!
You should check with your swap.
I nearly got the same, but my cpu is a P3 500....
And the system is not slow at all....

Could you explain a bit more?
I'm not an experienced user.

Hi,
You should check what is the size of the swap partition.
Let's suppose ypu have a 1 Go of ram, your should have a swap partition of 1 Go.

Franck, thanks again.

I have 512MB of RAM and a 4GB of swap.

¿Is that the problem?
¿How can I solve that exactly?

Sorry for my inexperence.

Regards (and happy new year to all, I forgot in previous e-mail)
