problem with yum on centos4.7
by Timothy Chan 24 Sep '09

24 Sep '09

Hi all, Sorry for this newbie question. I am having a problem with yum on centos 4.7. When I try something like "yum update" I get the following error: file:///misc/CO4/updates/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] No such file or directory: '/misc/CO4/updates/repodata/repomd.xml' Trying other mirror. Cannot open/read repomd.xml file for repository: update failure: repodata/repomd.xml from update: [Errno 256] No more mirrors to try. Error: failure: repodata/repomd.xml from update: [Errno 256] No more mirrors to try. I've tried "yum clean all" with no success. I'd be grateful for any help that I could get on this. Thanks. -tim

I'm comfortable using Fedora on my desktop, and I use CentOS on my server, so with CentOS set to update regularly her maintenance needs should be minimal, which suits both of us very well ;-) Anne -- New to KDE4? - get help from http://userbase.kde.org Just found a cool new feature?

mdadm size issues
by Nathan Norton 24 Sep '09

24 Sep '09

Hi, I am trying to create a 10 drive raid6 array. OS is Centos 5.3 (64 Bit) All 10 drives are 2T in size. device sd{a,b,c,d,e,f} are on my motherboard device sd{i,j,k,l} are on a pci express areca card (relevant lspci info below) #lspci 06:0e.0 RAID bus controller: Areca Technology Corp. ARC-1210 4-Port PCI-Express to SATA RAID Controller The controller is set to JBOD the drives. All drives have the same partition size # fdisk -l Disk /dev/sda: 2000.3 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 243201 1953512001 83 Linux .... I go about creating the array as follows # mdadm --create --verbose /dev/md3 --level=6 --raid-devices=10 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdi1 /dev/sdj1 /dev/sdk1 /dev/sdl1 mdadm: layout defaults to left-symmetric mdadm: chunk size defaults to 64K mdadm: size set to 1953511936K Continue creating array? As you can see mdadm sets the size to 1.9T. Looking around there was this limitation on older versions of mdadm if they are the 32 bit version. I am using the 64 bit most up to date version from Centos. If I go ahead and say yes create the array, mdadm says the following (I have zeroed the drives before adding them and creating the array) # mdadm --detail /dev/md3 /dev/md3: Version : 0.90 Creation Time : Thu Sep 24 23:48:32 2009 Raid Level : raid6 Array Size : 15628095488 (14904.11 GiB 16003.17 GB) Used Dev Size : 1953511936 (1863.01 GiB 2000.40 GB) Raid Devices : 10 Total Devices : 10 Preferred Minor : 3 Persistence : Superblock is persistent Update Time : Thu Sep 24 23:48:32 2009 State : clean, resyncing Active Devices : 10 Working Devices : 10 Failed Devices : 0 Spare Devices : 0 Chunk Size : 64K Rebuild Status : 0% complete UUID : cfa565db:4d0e07ca:b4d87a59:6e96cb06 Events : 0.1 Number Major Minor RaidDevice State 0 8 1 0 active sync /dev/sda1 1 8 17 1 active sync /dev/sdb1 2 8 33 2 active sync /dev/sdc1 3 8 49 3 active sync /dev/sdd1 4 8 65 4 active sync /dev/sde1 5 8 81 5 active sync /dev/sdf1 6 8 129 6 active sync /dev/sdi1 7 8 145 7 active sync /dev/sdj1 8 8 161 8 active sync /dev/sdk1 9 8 177 9 active sync /dev/sdl1 Anyone got any ideas?

Greetings, I'm currently using the c5-testing repo on CentOS 5.x/Redhat 5.x. I need to install APC (Alternative PHP Cache) but I'm getting a missing dependency error Missing Dependency: php = 5.1.6-23.2.el5_3 is needed by package php-devel. I was hoping somebody would be able to walk me through the steps of updating php-devel via the c5-testing repo? Thanks so much! Regards Kevin

Virtualizing an existing Centos 5.x installation
by Erick Perez 23 Sep '09

23 Sep '09

Hi all, i want to virtualize an existing Centos 5.x machine (intel xeon, 64 bit OS, Qlogic HBA) into a vmware 3.X VM that will not be connected to the SAN (hence no need for the HBA drivers). So i googled a while and found this link: http://virtualaleph.blogspot.com/2007/05/virtualize-linux-server-with-vmwar… However the link is quite old and I wonder if anyone here has done such conversion for something like Centos 5.x/Redhat 5.x Thanks, -- ------------------------------------------------------------ Erick Perez Cel +(507) 6675-5083 ------------------------------------------------------------

SATA controler req
by Philip Gwyn 23 Sep '09

23 Sep '09

Hello, I'm looking for a recomendation for a SATA controlers. In the range of 4-8 ports, either PCI or PCIe (for desktop use) and/or PCI-X, PCIe (for server use). I'd especially like it if the Linux driver was already in CentOS or easily added. Everytime I find something interesting, a google search shows up either the drivers is for 2.6.30 (ie, not CentOS), someone tried it and it was unstable, or it has a proprietary driver. They will be used as JBOD, with mdadm for RAID where I need it. Thank you, -Philip
