Interrupts from ethX sticking to one core
Hi all I'm running a NAT44 gateway on Debian Wheezy, kernel 3.2, and timers from eth[01] sticks to cpu0 even though I've set cpu_affinity to 0f (4 cores). This is a VM on ESXi. Setting affinity to a specific core works, but the kernel doesn't balance interrupts dynamically as I would have hoped it should, even when CPU load is at 95% (mostly soft interrupts). I also tried to install irqbalance without this having any effect. Drive used is e1000 (for the moment, will move to vmxnet3, but afaics from testing on another host, this didn't solve the problem). Is this a known issue? Any way I can fix this?

system load avg loops?!?
hei the log at http://karlsbakk.net/uptime.log.gz is a log create with while true do uptime >> log done this shows the system load is somehow looping?!? the system behaves well and is in production, but I don't really understand what the kernel is up to. same numbers are reported by top. sar and top etc reports no or little cpu and I/O load (<3%).

union mounting file systems... retry #1
Hi all After reading "Wonderful World of Linux 2.4" (Penguin Wizard) at http://www.linuxdevices.com/files/misc/WWOL2.4.html, I found somthing about union mounting file systems under "Linux internals", (seventh paragraph). I've been trying to find out how to do this, but I just fail. Some places I get the expression that I just have to mount the first file system, and afterwards, just use the option "-o union" to mount, but still, the originally mounted file system will disappear as soon as I mount another on top of it. Q: Is it possible to union mount file systems in linux 2.4 (currently using 2.4.5)? Q: Should I just go home and start doing my homework?

RE: union mounting file systems...
well... I just wondered how to (if possible) union mount two or more filesystems on a single mount point. The point that I want to bypass a bug/weakness in RedHat's installer is not really the case. I've tried to search the kernel mailing list archive, and find it's possible with mount -o union ... Problem is that I still can't see nothing but the last file system mounted on the mount point, so what is wrong? It may be an issue for other forums than lkml, but I really don't think RedHat is the place to go.

Hi all I just read the "Wonderful world of linux (2.4)", where it's said that the Linux kernel 2.4 supports so-called union mounted file systems.

I/O errors after moving to 2.4
Hi all After upgrading two 2-CPU servers (intel) from 2.2 to 2.4, users complain about their shell hangs for several seconds, sometimes minutes, when doing trivial stuff like doing a 'cat' or a 'vi' against a file. When trying to do more heavy I/O, the process in question will all of a sudden go Defunct and stay like that till some wonder lets it out in real life again. Does any of you know what this could be?

Dell PERC/Adaptec RAID support?
Hi all Some months ago, I asked this question, and thought about trying again. The PERC/something card, based on the Adaptec (DPT?) chipset, delivered by Dell on the Poweredge 2450 series servers among others, is currently only supported in specific distributions, and not in the official Linux kernels. As I want to run Linux-2.4.x, I can't find a kernel supporting the PERC, and this annoys me... Does anyone know when this will be merged into the main source tree?

Pavel I'm talking about file servers. Not merely a bloody PC. On a PC, hard disk space doesn't really cost anything and you can manually compress what you're not using. roy - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

- A file is saved to disk - If the file isn't touched (read or written to) within n days (default 14), the file is compressed. - If the file isn't compressed more than n percent (default 20), the file is flagged "can't compress". - All file compression is done on low traffic times (default between 00:00 and 06:00 hours) - The first time a file is read or written to within the n days interval mentioned above, the file is addressed using realtime compression. The second time, the file is decompressed and commited to disk (uncompressed). Oops, that means that merely reading a file followed by powerfail can lead to you loosing the file. Oops. eh.. don't think so. READ DECOMPRESS WRITE SYNC DELETE OLD COMPRESSED FILE or something Besides: you can do this in userspace with existing e2compr.

ext2 compression: How about using the Netware principle?
Hi With some years of practice with Novell NetWare, I've been wandering why the (unused?) file system compression mechanism in ext2 is based on doing realtime compression. To make compression efficient, it can't be made this simple. Let's look at the type of volume (file system) compression introduced with Novell NetWare 4.0 around '94: - A file is saved to disk - If the file isn't touched (read or written to) within days (default 14), the file is compressed. - If the file isn't compressed more than percent (default 20), the file is flagged "can't compress". - All file compression is done on low traffic times (default between 00:00 and 06:00 hours) - The first time a file is read or written to within the days interval mentioned above, the file is addressed using realtime compression. The second time, the file is decompressed and commited to disk (uncompressed). Results: A minimum of CPU time is wasted compressing/decompressing files. The average server I've been out working with have an effective compression of somewhere between 30 and 100 per cent. PS: This functionality was even scheduled for Win2k, but was somewhere lost... I don't know where... Questions: I'm really not a kernel hacker, but really... - The daily (or nightly) compression job can run as a cron job. This can be a normal user process running as root. Am I right? - The decompress-and-perhaps-commit-decompressed-to-disk process should be done by a kernel process within (or beside) the file system. - The M$ folks will get even more problems braging about a less useful product.
