Hi all, This morning I received this notification from mdadm: This is an automatically generated mail message from mdadm running on server-mail.mydomain.kom A Fail event had been detected on md device /dev/md1. Faithfully yours, etc. In /proc/mdstat I see this: Personalities : [raid1] md1 : active raid1 sdb2[2](F) sda2[0] 77842880 blocks [2/1] [U_] md0 : active raid1 sdb1[1] sda1[0]

I am trying to convert an existing IDE one-disk system to RAID1 using the general strategy found here: http://lists.centos.org/pipermail/centos/2005-March/003813.html But I am stuck on one thing - when I went to create the second md device with mdadm, # mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/hdb2 missing mdadm: error opening /dev/md1: No such file or directory And indeed,

Hello. A couple of years ago I installed two file-servers using kickstart. The server has two 1TB sata disks with two software raid1 partitions as follows: # cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sdb4[1] sda4[0] 933448704 blocks [2/2] [UU] md0 : active raid1 sdb1[1] sda2[2](F) 40957568 blocks [2/1] [_U] Now the drives are starting to be failing and next week

Hello, I just upgraded from Xen-3.3.1 to Xen-4.0.0. System is Gentoo, Hardware is DualCore AMD Athlon, 8GB RAM. The kernel was upgraded from OpenSUSE 2.6.27.29-0.1.1 to Gentoo-2.6.32-xen- r1. The first boot failed with an OOM error during kernel/initrd load, so I adjusted the dom0_mem option and had to increase it''s avalue from 256M to at least 400M until the dom0 could boot. At all

Hi all, I've installed CentOS 4.4 in a box which previously had dual boot (XP SP2 and Ubuntu) I can run CentOS without problem but I can't boot XP SP2. When I try it the system simply hangs...

Hi Everyone, My server is only seeing 4.8 GB out of 6 GB available. I don't know why. I have a CentOS 4.4 x86_64 server running on a Tyan s2895 with 6 GB of RAM (two 1 GB sticks and 2 2 GB sticks). I upgraded the RAM, powered up the server, and when CentOS was finished booting, checked the available RAM with free. This is what it's reporting: total used

Hi I have a Raid 1 centos 4.4 setup and now have this /proc/mdstat output: [root at server admin]# cat /proc/mdstat Personalities : [raid1] md2 : active raid1 hdc2[1] hda2[0] 1052160 blocks [2/2] [UU] md1 : active raid1 hda3[0] 77023552 blocks [2/1] [U_] md0 : active raid1 hdc1[1] hda1[0] 104320 blocks [2/2] [UU] What happens with md1 ?

I am new to R and have recently tried Tinn-R with very mixed and unexpected results. Can you point me to a Tinn-R tutorial on the web or a decent reference book? Thank you for your help; Charles McClure cmcclure at atrcorp.com cfmcclure at verizon.net

So I'm trying to RAID-1 this system which has two identical disks installed in it, and it isn't working for some reason. I started by doing a CentOS-4 install on /dev/sda1 as root, and with /dev/sda2 as my swap. I finish the install, yum update, and then I want to make the mirrors. I copy the partition table from one disk to the other: # sfdisk -d /dev/sda | sfdisk /dev/sdb I create

Hi there I have a little problem to get my include / exclude working: I want to sync /etc /home and /usr/local (and all files/dirs beneath) to REMOTEHOST:/dest There are some huge files in /home which I want to exclued I have set up an include/exclude file but I still get too much files. Also the excluded file is synced /usr/bin/rsync -av --exclude-from=excl --delete --numeric-ids --relative

Hi all, I am having trouble booting the ttylinux-xen guest os. I followed the example in the manual and exchanged the values to match my system. I also searched/read this mailing archive. This is the start command: ''xm create -c ttyvm'' where ttyvm is the config file It starts booting and then halts with the error: Root-NFS: No NFS server available, giving up. VFS: Unable to

I am stuck on a simple problem where an example works fine but the real one does not. I have a data.frame where I wish to sum up some values across the rows and create a new data.frame with some of old data.frame variables and the new summed variable. It works fine in my simple example but I am doing something wrong in the real world. In the real world I am loading a labeled data.frame. The

Sad to say one of my file servers was exploited and used to run a Phishing scam. Have identified subject virus amongst other things. It appears twice in a virus scan; /sbin/z (which I assume can just be deleted) and /sys/bus/serio/drivers/atkbd/description. The latter file is also present in identical uninfected machines. I have been unable to open the file, even with root privileges, although

I have been trying to set up printer sharing on the LAN.All machines are CentOS 5.2 fully updated. The problem server is a fresh build. The box it is replacing worked fine for many months. The problem appears to be a closed port 631 on the new box. iptables and ip6tables are stopped as shown by the output below. To confirm I was using nmap correctly I ran it against the old server first which

Hello, Sorry for the off-topic, but I've just installed CentOS 5 on my home box and I want to put the journal on another drive. I created a software RAID-1 device, /dev/md1, and formatted an ext3 file system on it. Now I want to move the journal to /dev/hda5. I've googled for this and the process appears to be: mkfs.ext3 -b 4096 -O journal_dev /dev/hda5 mkfs.ext3 -b 4096 -J

Hello all. I have a centos 4.4 box (2.6.9-42.0.10.ELsmp) with 7gig of ram that doesn't seem to be using swap (also 7gig now). I say "seem" because I've noticed ram utilization run around 95% (with oracle and friends running) and then firing up a couple apps to use that last 5% will stop the machine dead in it's tracks. I ran across some reading[0] about

System is CentOS 6 all up to date, previously had two drives in MD RAID configuration. md0: sda1/sdb1, 20 GB, OS / Partition md1: sda2/sdb2, 1 TB, data mounted as /home Installed kmod ZFS via yum, reboot, zpool works fine. Backed up the /home data 2x, then stopped the sd[ab]2 partition with: mdadm --stop /dev/md1; mdadm --zero-superblock /dev/sd[ab]1; Removed /home in /etc/fstab. Used

My test server was in very eavy load, running kolab's components: postfix, cyrus-imap and openldap A second test machine was sending, and reading emails as fast as it can. The CPU was never idle ! I left the server at about 17H30 and at 22H I find it "uncommitted" (difficult to work when the partition in read-only !) However the mount command report it as RW ! The /boot is still RW

Hi list, I'm new with UEFI and GPT. For several years I've used MBR partition table. I've installed my system on software raid1 (mdadm) using md0(sda1,sdb1) for swap, md1(sda2, sdb2) for /, md2 (sda3,sdb3) for /home. From several how-to concerning raid1 installation, I must put each partition on a different md devices. I've asked times ago if it's more correct create the

Is there a reason why after a software raid install (from kickstart) that md1 is always unclean. md0 seems fine. boot screen says md1 is dirty and cat /proc/mdstat show md1 as being rebuilt. Any ideas? Jerry --------------- my kickstart -------------- echo "bootloader --location=mbr --driveorder=$HD1SHORT --append=\"rhgb quiet\" " >
