Even some files are not actually in memory, but when you read them, you actually receive information from the kernel. In your case, read here for /proc/kcore: http://www.unixguide.net/linux/faq/04.16.shtml Run the command df to see the how your partitions are filled in. Run top to see which process consumes more resources. Note, that if you run firefox for several days w/o stopping it, it may eat a lot of resources. Cheers I prefer the term pseudo filesystem, since /proc does not reside in memory. As with any file system, procfs implements the functions defined by vfs, the virtual filesystem. The functions implemented actually read from, and in some cases write to, kernel data structures. The pathnames under /proc define which functions to call. There are a large number of such file systems: rootfs, sysfs, relayfs, tmpfs, and the list goes on. It works, because every filesystem is an implementation of vfs. Bill Anderson WW7BA Hmmm. I can't say I understand much of that :(. I've been informed off-list that /proc/kcore is simply my running kernel, so that's probably not the file I'm looking for. Can anyone suggest a simple CLI incantation to find all files larger than, say, 500MB? -- Bob openSUSE 10.3, Kernel 2.6.22.13-0.3-default, KDE 3.5.8 Intel Celeron 2.53GB, 2GB DDR RAM, nVidia GeForce 7600GS -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: [opensuse] AHCI / NCQ problem
Thanks Greg. I've been asking a bunch of people and no one had a clue what was going on. I wanted to enable this on a brand new MySQL server to help cope with I/O load but I'm not in a hurry, we'll see if Novell releases a patch, if not I can put a newer kernel once it arrives. Just out of curiosity, were the steps I took correct ? -- Best regards, Nick Zeljkovic -Original Message- From: Greg Freemyer [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 22, 2008 6:06 PM To: opensuse@opensuse.org Subject: Re: [opensuse] AHCI / NCQ problem On Jan 19, 2008 1:08 PM, Nick Zeljkovic [EMAIL PROTECTED] wrote: Hi, I'm having problems activating NCQ on Asus P5B-MX , Seagate Barracuda ST3250410AS (250GB) with Opensuse 10.3 installed.

The majority of that blacklist has been removed from the 2.6.24 rc series. I have not read about those patches having been released by Novell for the SUSE kernels. (A Novell employee found the problem and wrote the fix so I would hope his work will get into their kernel eventually.) So, you can either wait for that to happen (if it happens), or you can move to a recent KOTD kernel. FYI: I don't know how stable the KOTD kernels are right now. 2.6.24 has been very slow to get released, so I assume there must be some regression(s) they are trying to resolve currently.
