Hi all, Setup: I'm running 2 machines (amd64, 16GB) with FreeBSD 9-STABLE (Mar 14 so far) acting as NFS servers. They each serve 3 zpools (holding a single zfs, hourly snapshots). The zpools each are 3-way mirrors of ggate devices, each 2 TB, so 2 TB per zpool. Compression is "on" (to save bandwith to the backend, compressratio around 1.05 to 1.15), atime is off. There is no

We are running Zope behind Squid 2.4Stable6 with squid in acceleration mode. The squid box (dual Pentium III 1 GHz, RH 7.2, Linux 2.4.9-21smp, 2GB Ram) has during busy hours a normal load of 0.2-0.3 . From time to time we see spikes over some hours where the load average of the machine is higher than 1.5 although there are no spikes in the CPU utilization. Also there is no increase in the number

I made the mistake of looking at disk IO numbers in two different ways -- now I'm confused, because they give inconsistent answers. First way was using 'vmstat 10'. This gave me (apologies for wrapped lines): r b swpd free buff cache si so bi bo in cs us sy id wa st 2 0 2162944 4071928 162444 4218456 0 0 0 286 1103 528 3 2 95 0 0 1 0

I'm sure this has gotten some attention before, but I have two CSV files generated from vmstat and free that are roughly 6-8 Mb (about 80,000 lines) each. When I try to use read.csv(), R allocates all available memory (about 4.9 Gb) when loading the files, which is over 300 times the size of the raw data. Here are the scripts used to generate the CSV files as well as the R code: Scripts (run

On -STABLE as of Mon Jun 9 04:43:55 CEST 2003, "vmstat -s" shows on one of my boxes (uptime: 26 days): -1597015721 total name lookups cache hits (101% pos + 0% neg) system 0% per-directory deletions 0%, falsehits 0%, toolong 0% Weird. I'll have to cvsup again and hope this has been fixed :) -Regard, FH. -- Farid Hajji --

Dear All... I need some information regarding OCFS performance in my Linux Box, herewith is my environment details : 1. We are using RHAS 2.1 with kernel 2.4.9-e.27 Enterprise 2. OCFS version : 2.4.9-e-enterprise-1.0.9-6 3. Oracle RDBMS : 9.2.0.4 RAC with 5 Nodes 4. Storage = EVA 6000 with 8 TB SIZE 5. We have 1 DiskGroup and 51 LUNs configured in EVA6000. My Question is : 1. It takes arround 15

Hi, I think I must''ve done something incorrectly, but I can''t quite figure out what it is. To compare disk I/O performance in dom0 and domU, I ran the following two dd lines and observed vmstat 1 results (for blocks read/written per second), dd''s reported speed, etc. both dom0 and domU are allocated 512MB of RAM, so reading the 1GB file should not benefit from

I'm debugging a TxFax problem whereby the fax transmission fails. I suspect interrupt latency--some interrupt routine is holding its interrupt too long. I have all unnecessary services switched off and X is not running when I perform these tests. Some transmission are successful while others fail at random points. I've noticed that after I boot Linux, load zaptel, wcfxo, and wcfxs,

I was at a client site tonight to install OSLEC on his machine running asterisk 1.6.0.22 and DAHDI 2.2.1 installed via yum. I stopped asterisk and DAHDI, downloaded the latest version of DAHDI 2.2.1 (dahdi-linux-complete-2.2.1.2+2.2.1.1) and made the necessary changes to compile OSLEC with DAHDI, but I ran into compilation issues that I had never seen before. So as a test I deleted my

Hi OCFS Gurus... I have 2 questions for OCFS ver 1.0.10.1 1. What is the Maximum mount point suggested if we are using OCFS ? 2. Is there any method to tune the OCFS to booster the IO performance? Awaiting ur responses... Thanks in Advance... Rgds/Jeram

List, I've installed my CentOS Server running progress 9.1D database system, with only 15 users working every day, this server has 2GB RAM, so, my question is: Why the 2GB of RAM is always used? Even with only one user connected... How can I messuare the real RAM MEM used by my system split in proccess? Is there another tools which I use to compare the results from top. Or vmstat? Regards,

Hi ZFSers, I''ve been working on merging the Joyent arcstat enhancements with some of my own and am now to the point where it is time to broaden the requirements gathering. The result is to be merged into the illumos tree. arcstat is a perl script to show the value of ARC kstats as they change over time. This is similar to the ideas behind mpstat, iostat, vmstat, and friends. The current

Hi All, I have read many posts about problems with Asterisk on some systems. I also set up Asterisk on many different boxes. But I have never seen the following... There is an IBM X346 (3.4GHz Xeon) with one Sangoma A104. This system is currently idle, that means there is nothing running except Asterisk (1.2.7.1). We are handling no calls now, but if I do a vmstat, I get peaks in system load up

I've tested both 6.3 and 7.0-RC2, amd64 architecture, and have found the occurrence of an interrupt storm using an ASUS A8N-SLI Premium (nForce 4) motherboard with an AMD Opteron 175.

Hi all, I am attempting to tune a (RedHat 7.3) Linux box running samba 2.2.8a. This application is serving files to PC clients via samba, and the PC clients are uploading files to the server via ftp. Now for the specifics... These files are mpeg2 encoded video with bit rates ranging from 3Mbit/s - 20Mbit/s. When there is zero write activity against the disks I can kick off multiple concurrent
