Hello, I have a cluster with two nodes, with SLES10 as base system. First I powered on one node, and the system is working just fine. Then, when a second node was added, the performance came down pretty bad. Any hints or ideas about this behaviour?

Good day, everyone. I have SAN server build with Openfiler OS, with iSCSI mode turned on. I have two nodes, which connect to that server via iSCSI, using one of two active iSCSI partitions. I've installed ocfs2 1.3.3 with kernel 2.6.23.1, configured it, made ocfs2 partition and was successful in mounting it on both nodes. Everything works just fine, I can upload file from one node and

...tos 6.2 X64, and installed Webmin's Cloudmin as the front-end. Immediately when I was installing stuff, I could tell this new system I just built was not nearly as fast as the first one. I ran some CPU and disk benchmarking programs, and saw that while the CPU stuff tested similarly, the disk thruput was much different... Down-right poor in one of the guests! On both systems, /dev/md2 is a LVM reserved exclusively for KVM guests. So each guest is running in its own logical volume, in software raid. Thinking there may be something wrong with the HDs, I ran Bonnie ( http://www.coker.com.au/bon...

Dear Samba List, I have been reading the archives for mention of multi-homed Samba, and Samba over multiple subnets. I have two questions: 1) It is true that the nmbd daemon will only allow one IP address per subnet to be added to the local interface list? So if I had a Linux machine with two NIC cards connecting to the same HUB, using the same subnet, only one of these interfaces will be

Hello, This is one problem at the time :) I have a data frame df that looks like this: time partitioning_mode workload runtime 1 1 sharding query 607 2 1 sharding query 85 3 1 sharding query 52 4 1 sharding query 79 5 1 sharding query 77 6 1 sharding query 67 7 1

All, I'm not sure how to word this question but we're noticing a lot of our asterisk boxes no longer have multiple asterisk child processes. i.e. doing a 'ps ax' reveals only 1 asterisk PID when normally I'm used to seeing 8+ .. There is no rhyme or reason to it, and we're using the safe_asterisk script which has always worked in the past. Ast 1.2.4, zap 1.2.4, naturally..

Hi, I'm running centos-4.4 on an SMP system with 4 dual core opterons (2.4 GHz), and 16 GB memory. The disk drives are 500 GB SATA-Drives. Wondering about times for dd command performance and rm command performance in an empty machine (the filesystem has been made with "mkfs.ext3 /dev/sd...", nothing more) 1. Making a new 3 GB (1024 x 3megabytes blocks) file with dd needs 10.18

I never thought it would happen to me, but it did... I have read threads about slow copies from WinXX to Linux/Samba on the list in the past, but I don't recall a concise answer regarding what the cause was. THE PROBLEM: Trying to copy an 8 meg file from Win95 to my Linux/Samba box (named "Nemesis" - for good reason), the transfer speed slows to a crawl. The Win95 copy dialog box

Morning all... I have a Dedicated server in a data center in Germany, and it has 2 3TB drives, but only software RAID. I have got them to install VMWare ESXi and so far everything is going ok... I have the 2 drives as standard data stores... But i am paranoid... So, i installed Nexenta as a VM, gave it a small disk to boot off and 2 1Tb disks on separate physical drives... I have created a

The following is mainly a capture of parts of multiple off-line discussions within members of the Crossbow team (Gopi, Thiru, Roamer, May-Lin, Thirumailai, Nitin, KB, ...), I thought I''d open it up to other participants. Crossbow''s core scheduling involves switching a NIC (or individual Rx rings on the NIC) to polling mode. The receive interrupt will become not only rarer,

I'm very sorry about posting HTML. I know better then that and should have double checked my defaults. I'm reposting this hoping someone Is there a known bug that samba has on older machines in low memory environments? I have set up a 486 with 24Mb of memory with RedHat 7.1. I set it up to run dhcpd, xinetd, and samba. Samba was not run through xinetd. The samba server had a tendency

Hi all, just after sending a message to sunmanagers I realized that my question should rather have gone here. So sunmanagers please excus ethe double post: I have inherited a X4140 (8 SAS slots) and have just setup the system with Solaris 10 09. I first setup the system on a mirrored pool over the first two disks pool: rpool state: ONLINE scrub: none requested config: NAME

I''m currently researching an upgrade to (raid1-ed) btrfs from mostly reiserfs (which I''ve found quite reliable (even thru a period of bad ram and resulting system crashes) since data=ordered went in with 2.6.16 or whatever it was. (Thanks, Chris! =:^)) on multiple md/raid-1s. I have some questions that don''t appear to be addressed well on the wiki, yet, or where

Hi, I am currently running a 10 Node OCFS2 Cluster (version 1.3.9-0ubuntu1) on Ubuntu Server 8.04 x86_64.
