mdadm --create on Centos5?
by Les Mikesell 29 Aug '07

29 Aug '07

Is there some new trick to making raid devices on Centos5? # mdadm --create /dev/md3 --level=1 --raid-devices=2 /dev/sdc1 /dev/sdc1 mdadm: error opening /dev/md3: No such file or directory I thought that worked on earlier versions. Do I have to do something udev related first? -- Les Mikesell lesmikesell(a)gmail.com

29 Aug '07

I 'just' noticed that my USB DVD/CDRW is not automounting in my Centos 5 installs. Various USB drives do: USB flash drives, USB multi card drives, and USB IDE converters. I can issue a: mnt /dev/cdrom /media but why is this needed?

After playing with conga/luci i'm wondering that it's not possible to reset and/or remove the generated cluster configuration. Somebody knows how to achieve this? I did not find any hint in the RH manuals.

Different Video card. No PS/2 keyboard of mouse on the decTOP INTEL vs AMD cpu Could it work?

NCQ in the 2.6.18 kernel
by Harford, Ken 29 Aug '07

29 Aug '07

Hi All, Newbie here! I was wondering if anyone has succeeded in getting NCQ enabled with the ServerWorks chipset in the 2.6.18 kernel. I am running a Dell 1435/CentOS 5.0-x86_64 with dual 250GB Western Digital NCQ supported drives, when I load up the OS I get these messages: ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: ATA-7, max UDMA/133, 488281250 sectors: LBA48 NCQ (depth 0/32) ata1.00: ata1: dev 0 multi count 8 ata1.00: configured for UDMA/133 scsi1 : sata_svw ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata2.00: ATA-7, max UDMA/133, 488281250 sectors: LBA48 NCQ (depth 0/32) ata2.00: ata2: dev 0 multi count 8 ata2.00: configured for UDMA/133 scsi2 : sata_svw Any ideas?

Mapping to Samba
by Scott Moseman 29 Aug '07

29 Aug '07

Using GUI methods (read: easy for most users), is there a way to map to a Samba share and have it accessible to all applications? Going through Nautilus I'm able to create a link to the shares, but they're not accessible from many applications. And, obviously, this is going to be something that changes per user (different mappings, different credentials, etc), so I can't use a static mapping on the machines. I could live with /etc/fstab entries if they could be dynamically adjusted based on the user that's logging into the system. How do other people handle this situation? Thanks, Scott

NIS probs - Login and no home dir -help
by Scott Ehrlich 29 Aug '07

29 Aug '07

I'm trying to configure two things on my RH 5 server with dual-boot CentOS 5 (out-of-box) and Windows XP w/SP2 (fully patched) clients: - NIS/NFS: I have managed to get user logins, but all accounts produce Can't Find Home Directory, Using Root! The error logs, when trying to mount any NFS directory, is the server claims permission denied. I've reviewed many web pages and reviewed my config files carefully. Just a matter of finding the winning config. Firewall and SELinux are disabled, and the machines have been rebooted many times. - Samba: Ideally, I think if I can get NIS/NFS working fine, it would make sense that when Windows users log in (I've gotten samba to permit the XP systems to be added to samba with samba acting as the PDC), they log into their UNIX accounts. But, upon attempted login, Windows produces the famed small alert window saying Roaming Profiles cannot be located, Windows is creating a temporary environment that will not be saved upon logout. What is the magical Samba config/line to permit Samba/domain logins to read from the server's UNIX side and give the Windows domain user their UNIX home directory for login, and have their UNIX home directory as a mapped drive (effectively their roaming profile)? Thanks. Scott
