Hello all, |
2 |
|
3 |
Running a box with 2x1TB software raid disks. |
4 |
A while back I read up about disk write caching and it's pros/cons. |
5 |
|
6 |
I then decided to disable it on my box. |
7 |
Edited /etc/conf.d/hdparm and added -W0 for sata_all_args. |
8 |
And added it to the default runlevel. |
9 |
|
10 |
It works, on bootup it turns off write caching. |
11 |
But a while later when KDE is up and running and I check with hdparm -W |
12 |
/dev/sd? write caching is on again. |
13 |
|
14 |
Now, I have two questions, |
15 |
How can I find out what turned it back on, and how can I prevent it? |
16 |
|
17 |
Is it necessary/prudent to turn it off in the first place? |
18 |
|
19 |
At the moment I run a cron job that checks every 10 minutes and turns it |
20 |
off if it is enabled. But that feels like a somewhat ugly solution... |
21 |

Kind regards, |
