Re: [CentOS] Slow gfs performance
by James Thompson 09 Jun '08

You don't mention it but I assume you are running on Fiber Channel not iSCSI? I am running GFS using CentOS 5.1 from two servers using iSCSI. I have Device Mapper Multipath setup so that makes my performance characteristics a little different but I have tuned the servers with the following commands: gfs_tool settune <mountpoint> demotes_secs 600 gfs_tool settune <mountpoint> scand_secs 10 gfs_tool settune <mountpoint> statfs_slots 128 The first two I have set until 5.2 drops which will contain an additional GFS tuning parameter, glock_purge. Update 5 of CentOS 4 may already have the glock_purge parameter available. Run the command 'gfs_tool gettune <mountpoint>' and see if glock_purge is listed. It should be set to zero by default. If it is there you can refer to this brief write up on tuning with glock_purge since you will not want to use the demote_secs and scand_secs settings I am using: http://open-sharedroot.org/Members/marc/blog/blog-on-gfs/glock-trimming-pat… Also, as a further note, your particular usage scenario will dictate what tunings are appropriate. I am not familiar with Oracle's usage of I/O but will both servers be accessing the same data on disk (particularly with regards to writing) at the same time? -James Thompson ----- Original Message ----- From: "lingu" <hicheerup(a)gmail.com> To: centos(a)centos.org Sent: Monday, June 9, 2008 4:54:44 AM GMT -05:00 US/Canada Eastern Subject: [CentOS] Slow gfs performance HI, Sorry for repeating same mail ,while composing that mail i mistakenly typed the send button.I am facing problem with my gfs and below is the running setup.

wpa_supplicant and machine freezes
by Timothy Kesten 09 Jun '08

09 Jun '08

Hi Folks, I'd like to install my USB-WLAN-Stick Netgear WG111v3. Ndiswrapper works correct after installing Kernel-Modules from atrpm ndiswrapper-kmdl-2.6.18-53.1.19.el5.centos.plus-1.52-16.el5.i686.rpm. But by calling wpa_supplicant with wpa_supplicant -i wlan0 -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf -d machine freezes. My wpa_supplicant.conf: ctrl_interface=/var/run/wpa_supplicant eapol_version=1 ap_scan=1 network={ ssid="MyNet" scan_ssid=1 proto=WPA key_mgmt=WPA-PSK pairwise=TKIP group=TKIP #psk="MyPSK" psk=9050ec6fe020b1738fce16c93c33b3809b9e62d5e6bf955518076eb2d7263 } With this configuration it works correct with Sidux (a debian clone). But with CentOS 5.1 ....??? No hints in /var/log/messages or dmesg available. Has somebody an advice/ a solution for me? More information needed? Thx Timothy

I've even tried running MySQL with a database populated with identical data on localhost (even tried 127.0.0.1), but there is no difference in performance. Delays in the connection to the db server is still around 20-30 seconds. So, the problem has to be with either the php-mysql module, PHP itself, MySQL or then it may be hardware related.

[CentOS] Network problems on new CentOS 5 install on P35, ICH9R mobo
by Dick Roth 09 Jun '08

09 Jun '08

Had to replace dying cpu and mobo, so also replaced IDE with new SATA drive. Installed from latest ISO onto SATA and can't get networking to lease an IP address from my ISP (Comcast). The network utility always comes up with a private address (192.168.0.2) instead of Comcast IP. To add to confusion, if I boot into old IDE drive, I get proper network connection to internet, but lose my swap! Particulars: mobo=Gigabyte P35-DS3R SATA Controller=AHCI PATA Controller=JMicron 20360 new drive=ATA WDC WD1600AAJS-2 old drive=WDC WD400JB-00JJA0 DVD-RW=Pioneer DVR-112D (PATA) NICs=eth0=Realtek RTL-8029(AS) (DHCP) eth1=Realtek RTL-8029(AS) (Static) Has anyone seen this? Will 5.2 help with this situation? Been working on this for days!

DMA mode
by David Mackintosh 09 Jun '08

09 Jun '08

Hi folks, I have an HP Proliant 140DL G2 server with what appears to be an IDE drive in non-DMA mode. Performance on the server is extremely bad when large amounts of disk activity is taking place. I think the problem is that my drive is not in DMA mode: # hdparm /dev/hda /dev/hda: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 16383/255/63, sectors = 80026361856, start = 0 ...but I can't set it on: # hdparm -d1 /dev/hda /dev/hda: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted using_dma = 0 (off) ...which I think is because the IDE controller isn't really recognized, or is pretending to be a SATA controller: # lspci -v | less 00:1f.2 IDE interface: Intel Corporation 82801EB (ICH5) SATA Controller (rev 02) (prog-if 8a [Master SecP PriP]) Subsystem: Hewlett-Packard Company: Unknown device 3208 Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 193 I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at <unassigned> I/O ports at 1470 [size=16] All the google hits I've seen so far imply I have to build a kernel module but I'd rather not get into the business of rolling my own kernel if I don't have to. I spun through the HP support page for this box/OS combo, and I don't see any SATA/IDE/ATA drivers, only SCSI/SAS drivers. So before I continue on, can I get a sanity check here -- am I barking up the right tree? -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com | http://www.xdroop.com

3Ware 9690SA
by Ruslan Sivak 09 Jun '08

09 Jun '08

I successfully installed CentOS on 3ware 9650SE controller. Due to some issues with compatibility with my motherboard, I replaced it with a 9690SA. Now the system won't boot (although interestingly enough, it find the boot menu fine, just won't boot past a certain point in the bootup phase. I thought I would reinstall, but anaconda doesn't find the raid array. 3ware does have drivers on their site, but I'm not too sure how to get them on my system? Russ
