When a new system CentOS-4.4 is built the swap partition is always reversed... Note md3 below, the raidtab is OK, I have tried various raid commands to correct. swapoff -a raidstop /dev/md3 mkraid /dev/md3 --really-force swapon -a And then I get a proper ourput for /proc/mdstat, but when I reboot /proc/mdstat again reads as below, with md3 [0] [1] reversed. [root]# cat /proc/mdstat

Hello, yesterday night I had a problem with my server located at a hoster (strato.de). I couldn't ssh to it and over the remote serial console I saw "out of memory" errors (sorry, don't have the text). Then I had reinstall CentOS 5.5/64 bit + all my setup (2h work), because I have a contract with a social network and they will shut down my little card game if it is not

Hi all, After rebooting my CentOS 5.5 server, i have the following message: ================================== Red Hat nash version 5.1.19.6 starting EXT3-fs: unable to read superblock mount: error mounting /dev/root on /sysroot as ext3: invalid argument setuproot: moving /root failed: No such file or directory setuproot: error mounting /proc: No such file or directory setuproot: error mounting

Hi. I'm using e2fsprogs 1.23 on a Roswell system with a patched 2.4.7 kernel (using patch ext3-2.4-0.9.5-247) and am trying to create an ext3 filesystem whose journal is located on another device. The incantation I'm trying is: mke2fs -j -J device=/dev/hdc2 /dev/hdc3 I keep getting an error along the lines of "mke2fs: Journal superblock not found". I've tried creating

Hi Guys, I had a strange problem yesterday and I'm curious as to what everyone thinks. I have a client with a Red Hat Enterprise 2.1 cluster. All quality HP equipment with an MSA 500 storage array acting as the shared storage between the two nodes in the cluster. This cluster is configured for reliability and not load balancing. All work is handled by one node or the other not both.

Hi R users, I am trying to use the optim function to maximize a likelihood funciton, and I got the following warning messages. Could anyone explain to me what messege 31 means exactly? Is it a cause for concern? Since the value of convergence turns out to be zero, it means that the converging is successful, right? So can I assume that the parameter estimates generated thereafter are reliable MLE

Hi, I''m trying to run btrfs-convert on a system that has three raid partitions (boot/md1, swap/md2 and root/md3). When I boot a rescue system from md1, and try to run "btrfs-convert /dev/md3", it complains that /dev/md3 is already mounted, although it definitely is not. The only partition mounted is /dev/md1 because of the rescue system. When I replicate the setup in a

Hi everyone. This isn't specifically a CentOS question, since it could apply for any distro but I hope someone can answer it anyway. I took the following steps but was puzzled by the outcome of the test at the end: 1. Create a RAID1 array called md3 with two 750GB drives 2. Create a RAID1 array called md9 with two 500GB drives 3. Initialise md3 then md9 as physical volumes (pvcreate) 4.

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 at gmail.com

I recently set up a new system to run backuppc on centOS 5 with the archive stored on a raid1 of 750 gig SATA drives created with 3 members with one specified as "missing". Once a week I add the 3rd partition, let it sync, then remove it. I've had a similar system working for a long time using a firewire drive as the 3rd member, so I don't think the raid setup is the cause

I am trying to create an additional domain and have created a configuration file based on the examples. When I try to boot the domain, it eventually hits a Kernel panic, as follows: Red Hat nash version 4.1.18 starting Mounted /proc filesystem Mounting sysfs Creating /dev Starting udev Creating root device Mounting root filesystem mount: error 6 mounting ext3 mount: error 2 mounting none

CentOS 5, original kernel (xen and normal) and everything, Linux RAID 1. I rebooted one of my machines after doing some changes to RAID/LVM and now the two RAID partitions that I made changes to are "gone". I cannot boot into the system. On bootup it tells me that the devices md2 and md3 are busy or mounted and drops me to the repair shell. When I run fs check manually it just tells
