Updating Kernel with Up2date
by Rajeev R Veedu 20 Aug '06

20 Aug '06

Hi, I have installed Centos 4.3 64bit with Kernel 2.6.9-34 using a driver disk for 3ware raid controller. I had partitioned this raid disk with Parted, and made ext3 file system on it. mounted and updated in /etc/fstab. It automatically mounts when I reboot the machine. Now when I do an up2date and update the kernel to 2.6.9-34-0.2 the system doesn't recognize the raid disk. I have checked the /lib/modules/2.6.9-34.0.2.ELsmp/kernel/drivers/scsi folder and found the files 3w.9xxx.ko and 3w.xxxx.ko. But when the system boots with the new kernel it doesn't detect the 3 ware Raid disk. Any idea why this could happen. ? Thanks Rajeev R Veedu

CentOS vs. Nokia Phones
by Rodrigo Barbosa 19 Aug '06

19 Aug '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have been trying to access my Nokia 6230 using a DKU-2 data cable from CentOS, with some weird results. Interesting thing is that I have VMWare installed on this machine and, if I install the Nokia Suite inside it, it can access the phone without problems. So all hardware related parts are working. Anyway, kernel load the cdc_acm module, and gives me /dev/ttyACM0. Accessing this tty (cu -l, minicom, take your pick), I can issue AT commands and get responses. So far so good. But then I try to access it using some software (gnokii, obex, gammu), it simply won't work. Trying to use usbserial instead of cdc_acm gives exactly the same result. Does anyone has any better experience with this setup ?

Tape backup question.
by Geert Batsleer 19 Aug '06

19 Aug '06

Hello, I want to backup my PE2800 on tape but I'm not sure how to do this. My PE2800 has a RAID5 setup with 2 72GB SCSI disks and a Seagate DAT-2 72GB internal tape-streamer and I'm running Centos 4.3 with the latest yum updates. I'm not sure if this tape-streamer is recognised by the OS properly because it doesn't show up along with my DVD/floppy I also recieved with the server a copy of Galaxy Express software from Dell but from what it looks this seems to be more of a client/server backupprogram and not really functional on a standalone server. So how does one backs up + restores a complete HD (incl. MBR) like a ghost image or something on a tape. Any good software or howto's you can suggest would be much appreciated. kind regards, Geert

Big load
by Marek Dabrowski 19 Aug '06

19 Aug '06

Hello friends I've problem with my Centos 4.3. On start some information: 1. serwer HP DL 380 x Intel(R) Xeon(TM) CPU 3.40GHz 2. RAM 4GB 3. HDD storage FC 4. kernel 2.6.9-34.0.2.ELsmp #1 SMP This serwer is working with another one (that some configuration) in RHEL cluster (locking by DLM), as a file serwer with samba-3.0.22. Samba have about 100 simultaneus sessions. Problem is with load of my system. It's growing up. I disabled/enabled samba processes, disabled backup system, disabled antyvirus for samba, but this didn't help. CPU utilization is 5-10%, ram utilization ~2GB. I don't have any idea what's wrong. Any suggestion? Regards Marek Sorry for my english

info: Apache 2 bandwidth limitation problems solved
by dan1 19 Aug '06

19 Aug '06

Hello all, Just a little info for users of Apache 2 amoung you who use bandwidth limitation, mainly ISPs. I was using mod_bwshare (old: bw_share), one of the only bandwidth limitation by IP available, during one year with big problems for the bandwidth limitation (by IP and maximum amount), on CentOS 4. That introduced a slowness on the apache server and depending on the main DNS used, it did result in pages being stuck for about 5 seconds every so often. It was hard to define where the problem came from (apache, php, mysql, etc..). Now the problem has been found, and this has been solved in mod_bwshare V0.2.0. It did force a double hostname lookup before, which was not needed and slowed down the user's response time of apache. The DNS requests are now also much less frequent, only one per new IP logged, instead of more than 10 per seconds before. I think that now it is very reliable (tested on my production server), and thus it might interest some of you. Hope this helps someone, sorry if it disturbs anybody but I felt this important to tell it here as I had no answer when I posted my requests to find the solution. Greetings, Daniel

hello all, I am trying to expand my /var file system which resides on a logical volume. I successfully issued the lvextend command. However when I try to issue the ext2online command I receive a return code of 3 which the man pages indicates: ext2online /var ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b ext2online: group 0, block 7 not reserved ext2online: unable to resize /dev/mapper/root_vg-lv_var echo $? 3 3 Error in pre-resizing (user space) operation Can someone tell me what I'm doing wrong. I would prefer doing this online... thanks, James
