df -h shows system at 100% used, but there is space left
by dnk 29 Apr '09

29 Apr '09

Has anyone seen output like this before? Notice on my /dev/md0 That it reports 100% used, but also 5.3 Gb available. What would cause this? # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 71G 1.6G 66G 3% / /dev/sda1 99M 22M 73M 23% /boot tmpfs 506M 0 506M 0% /dev/shm /dev/md0 903G 851G 5.3G 100% /home Thanks in advance! d

kickstart problems...
by John Doe 29 Apr '09

29 Apr '09

Hi, I am creating CentOS install usb keys and, apart from a few problems, it mostly works... 1. OT: My server HP does not seem to want to boot on it if I set the write protection on. 2. Anaconda tries to fetch the ks.cfg too early... It detects sda, then detects the RAID adapter, then re-detects sda with a "waiting for device to settle before scanning". Anaconda tries to access the ks.cfg file in the middle of this waiting. If, once the detection is over (just 2-3 seconds later), I retry, it works. 3. Error message "cannot mount read/write, will mount read-only" (I like to write protect) 4. OT: fs corruption ont he USB keys... I copy the iso file on the key (no error message), then compare it to the original and some random differences appear. I noticed in the logs: "ext2_new_block: Allocating block in system zone - block = 65536" "ext2_free_blocks: bit already cleared for block 88678" "ext2_free_blocks: Freeing blocks not in datazone - block = 3003818537, count = 1" Any idea how to fix 2. and 3. ? Thx, JD

Update notification
by lhecking＠users.sourceforge.net 29 Apr '09

29 Apr '09

CentOS 5.3 New updates available used to be flagged in the (Gnome) desktop notification area, but I don't get them any longer. What could be the problem? yum-updatesd is set up with the default configuration (dbus), and on the machines I changed the notification to email, I do indeed receive these emails.

Dell mirror raid boot problems
by Gregory P. Ennis 29 Apr '09

29 Apr '09

Everyone, I was recently given a Dell raid 386 server that had drives that had gone bad. I replaced the drives with a couple terrabyte sata Seagate drives, and set up the bios for a mirrored raid configuration. I was able to install Centos 5.2 without difficulty, but when it was time to perform the 1st boot it went to grub instead of booting off of one of the mirrored drives. I could not figure out how to boot through grub, so I changed the bios to look at both drives unmirrored. At that point I was able to boot to one of the drives, and the second drive was not mounted. The raid logic is within the bios and mother board of the Dell machine. Can any of you point me to some literature about making this system work as a mirrored raid system. Thanks, -- Greg Ennis

Wake On LAN
by James Bensley 29 Apr '09

29 Apr '09

Hey Listees I can not work out how to get my Dell NF500 III server to use wake on LAN using the on board Broadcom NetExtreme II BCM5708 NIC card? I'm running Cent OS 5.3 final (i386). Basically, If I had windows server 2k3 installed I know that the cards & mobo etc support WOL I would just have to tick a little box under the NIC card properties saying "allow wake on LAN" (or words to that affect). How can I enable WOL for my NIC card? I have two identical servers so I have tried putting one to sleep (via either setting the hibernate time down to 5 mins and waiting for it to time out and hibernate or by running the following as root: echo shutdown > /sys/power/disk; echo disk > /sys/power/state) and waking it up with ether-wake and WOL (an rpm package) but neither worked, also with a windows WOL client from a windows server which I know works as it is regularly in use but the system didn't come up. The light is glowing green on the mobo just next to the two on board NIC's (both are the same BCM5708's); the light is on but nobodies home? What setting might I be missing within CentOS its self to keep the cards alive when the power is out? Any help is greatly appreciated.

USB device not connected (CentOS 5.3)
by Bart Schaefer 29 Apr '09

29 Apr '09

I just tried this with CentOS 5.3 as well, and got exactly the same symptoms and dmesg output. (As a point of comparison, Ubunu 8.04 on my work laptop is able to access the drive.) Obviously "not detected" is a misapprehension, though I'm puzzled why "lsusb" doesn't show it. The device is there even though the partition table can't be read. ---------- Forwarded message ---------- From: Bart Schaefer <barton.schaefer(a)gmail.com> Date: Tue, Apr 28, 2009 at 10:58 AM Subject: Re: [CentOS] USB device not detected (CentOS 4.7) To: CentOS mailing list <centos(a)centos.org> On Tue, Apr 28, 2009 at 10:01 AM, Craig White <craigwhite(a)azapple.com> wrote: > On Tue, 2009-04-28 at 09:48 -0700, Bart Schaefer wrote: >> I recently purchased an I/O Magic USB enclosure for 3.5" IDE > ---- > check what it says about the drive in dmesg after you plugged it in.

Yum Update issues

make fails building Perl 5.10.0 on C5.3 x86_64 (new install)
by Mark Pryor 28 Apr '09

28 Apr '09

Hello, I tried to build Perl 5.10.0 on x86_64 using defaults $./Configure -des $make ------------- snip last few lines of errors -------- perlvars.h:178: warning: ISO C forbids conversion of function pointer to object pointer type perlvars.h:186: warning: ISO C forbids conversion of function pointer to object pointer type make: *** [globals.o] Error 1 ------------ end snip --------------- I'm not surprised since FC10 has several patches in the perl.spec for x86_64 Looks like I'm not going to get by without digging into what they did. Hope someone here can give me a scouting report. -- Mark
