4392Re: Cool'n Quiet on LS2 MIPS
- Nov 19, 2005The relevant process on LS2 is "mc_ctld". It seems to behave exactly
as "ppc_uartd" on LS1, although on my LS2 (Openlink 052b) the fan at
some point seems to start back up again after the script turns the fan
off, even though the disk hasn't start spinning again. To get around
this, I modified the script so that when it checks the fan status and
sees the fan speed is in theory already set to low, I echo the command
again to set it low just in case mc_ctld has set it high again.
Also, regarding the logs, my LS2 with Openlink has all the logs on a
ramdisk that gets backed up and restored to the HDD on
startup/shutdown and once a day during the log rotate cron job, thus
avoiding spinning up and shutting down the disk just to update the logs.
