| |
Hi!
I've got four IDE drives (hda..hdd). They're told to go to sleep after a while. But when some application needs to use a file on one of them, both the application itself and parts of the system (other tasks) get frozen for some seconds if the given drive needs to spin up first.
I think this wait period should only affect the kernel fs thread that tries to read from the hd, but not the applications?
For example, on my 64MB box (w/o X running), an application trying to write some few MBs to an IDE drive that's "sleeping" will have to wait for a few seconds, although there's enough memory that the fs cache could use to store the data to be written in while the drive spins up. This doesn't happen here; the app is held for seconds (in which it could calculate/parse more data, but it can't, since it's held in a write() call).
Ideas?
This is 2.1.129 speaking.
ciao, johnny -- Trust no-one.
