Hello, I converted one of my servers to ext3 and load average numbers went up. Now they are ~2-3 while on ext2 LA was <0.4. And I'm constantly seeing processes and kjournald in D state. vmstat confirms that. But even in such LA CPUs are ~99% idle. What can be wrong? RedHat 7.1 kernel 2.4.18-18.7.xsmp. SCSI cards: Compaq RAID array controller (cciss) and Q Logic ISP1020 (isp_mod).

Hello, Is there some document about ext3 performance tuning and choosing the right type and size of journal? Except RedHat's white paper. From what I read I understood that for typical operations data=ordered is prefered. For the cases when there are many writes not appending to files data=journal is the choice. And if I want to get the most performance or in case where program is doing

Hello, We have long running problem with NetApp filers. When we connect server to the filer sequential read performance is ~70MB/s. But once we run database on the server seq read performance drops to ~11MB/s. That's happening with two servers. One is running Oracle another - MySQL. During speed tests database load is very light (less than 1MB/s of reads and writes). During the tests NetApp

Found the simpliest way of seeing I bug I encountered doing "R CMD check --use-gct": Just launch R (with --vanilla), and do this: > ?gctorture # this work > gctorture() > ?gctorture Error in gzfile(file, "rb") : can only weakly reference/finalize reference objects # this does not It seems that when gctorture() is on gzfile() doesn't work.

Hello, I noticed in my logwatch file I have an error with my rndc key. I could 'play' around with it and may fix it but most likey just hose things up. I think I see the problem but not 100% sure. I think the key file has 3 different names. Here's the error: **Unmatched Entries** /etc/named.conf:23: couldn't find key 'rndckey' for use with command channel

Hi! Uhm are attributes just something like additional members of a class, other than those that come from the names of columns in the table? I''ve got images table, which has ''name'' column. I''ve added support for creating thumbnails out of uploaded pictures and i''d like to have an easy way of accessing them in my views. How to do it? I.e. my image

Hello, How to upgrade existing ext3 partition to new features? Moved from RHEL3 to RHEL4. I had to install from c0d0p6 so partition could not be reformated during install.

http://www.sample.banga.lt/crash.gif System - fully (except kernel) updated RedHat 7.3. Filesystems - ext3 in default ordered mode. What could be the cause of the crash? Kernel update will solve the problem? Thanks, Mindaugas

Hello, Just became curious - is O_DIRECT already supported on ext3 or not yet? And a little bit offtopic :). Is that flag supported on some other filesystem other than ext2? Thanks, Mindaugas

Hello, Maybe it's already FAQ but how to hide .journal file on rootfs? I upgraded filesystems on one of my servers from ext2 to ext3 and everything went smoothly. I'd like to avoid booting from alternative media because server is in production. FS update done together with server's kernel update. Thanks, Mindaugas

Hello, What do you use to manage virtual Xen machines? Nothing complex though preferably. :) I've already converted some servers for a Xen dom0 and starting to loose the picture - which VM runs where and how much resources left on each server. Regards, Mindaugas

Hello, After some fiddling with the server now I have broken RAID1 with the "current" mirror on the disk with few unreadable sectors. If I try to re-add other disk to the mirror resync goes till those bad sectors and then starts from the beginning. And so on. Is it possible to somehow force resync to continue even after errors? Manual resync with dd would require a bit too long

Hi all. I've just installed dovecot v2.1 in a multihomed, multiinstance setup, It took me two days to convert the old v1.1 configs, now everything works like charm! But. :) I have several maildir mailboxes, I decided to use the sdbox storage type instead. I ran into difficoulties using the dsync util. My virtual users are in an OpenLDAP DB on a differnet machine, and I do not have access

Hello everyone, I'm trying to set up a Asterisk server. I have two cards - one is an BeroNet BN2S0 with two ISDN lines (4 channels): http://www.adcomtec.com/webstore/beronet_bn2s0.php?cat=90 and a Rhino R8FXX with one FXO module and two FXS: http://www.voipsupply.com/product_info.php?products_id=2940 I would like to set up an Asterisk server with 8 phones, which will share the phone

Hello everyone, What is the most efficient & simpliest way to convert all components of a list to separate columns in a matrix? Is there an easy way to programmatically "pad" the length of the resulting shorter character vectors so that they can be easily combined into a data frame? I have the following code that stores the 2 compoents (of differing lengths) in the same character

According to... https://github.com/rurban/smhasher/blob/master/README.md Bernstein has quality problems (while xx is as good as you get in a non-crypto hash), and xx is 7x (32 bit) - 12x (64 bit) faster. That's on long strings. It would be worth checking the startup overhead for typically short identifiers in programs. See later on in the README: "When used in a hash table the
