I am new to ext3 + external journal. Is there any howto I can look at? this is what I understand 1. mke2fs -O journal_dev /dev/md5 2. mke2fs -J device=/dev/md5 /dev/md0 3. mount /dev/md0 / -t ext3 ( hmm.. what do I need to put on fstab?? ) /dev/md5 is a two drive RAID 1 partition /dev/md0 is a 4 drive RAID 5 partition. questions: 1. I am running RedHat 9.0. what extra software I need to

Hi all, I issued the commands on a single disk system: with two partitions / is linux sda1 and /home is sda3 yum -y update yum -y install e4fsprogs reboot umount /home tune2fs -O extents,uninit_bg,dir_index /dev/sda3 e2fsck -yfDC0 /dev/sda3 That worked just fine. I then had a different system that is software raid. where / is linux and md0 and /home is md1 yum -y update yum -y

Good morning, I try to use the last release of ext3 patch with a 2.4.10 linux kernel. I have two troubles : - when the kernel is booting, I receive : NET4: Unix domain sockets 1.0/SMP for Linux NET4.0. VFS: Mounted root (ext2 filesystem) readonly. Freeing unused kernel memory: 208k freed Adding Swap: 128480k swap-space (priority -1) Adding Swap: 128480k swap-space (priority -2) Why my root

We are having problems remounting an ext3 filesystem using an external journal device. The filesystem in question was working fine until the server was rebooted. This is what we see on dmesg when trying to mount: EXT3: failed to claim external journal device. The external journal lives on a LVM2 logical volume and it seems to be accessible ( we can dumpe2fs and see filesystem information).

Hello, I just need a little clarification regarding applying the ext3 patch to the latest kernel. I have 2.4.7-10 that came with RH 7.2. I have ext3 running. I need to upgrade those (to get some USB device working). So I got the latest kernel, 2.4.14, patched it with the ext3-2.4-0.9.15-2414 patch, picked ext3 from 'make xconfig', built the kernel, but the new stuff in /boot, etc.,

Everyone, We just had a pretty bad crash on one of production boxes and the ext2 filesystem on the data partition of our box had some major filesystem corruption. Needless to say, I am now looking into converting the filesystem to ext3 and I have some questions regarding ext3 and Linux software RAID. I have read that previously there were some issues running ext3 on a software raid device

I am using SuSE 7.3 compiled ext3 support into the kernel and installed it. All my partitions load up as ext3 except / . I ran tune2fs several times, still doesn't take on the / drive. Most recent dumpe2fs -h show no features on that drive=, I keep going around in circles, removing .journal from / and running tune2fs but it never works for / What am I doing wrong? ( thanks in advance)

Hello Is it possible to externalize the journal of an already existing (journal inside) ext3 FS ? Here's what I did to create a new FS with external journal for /dev/emcpowerl2 on /dev/emcpowerl2 mke2fs -O journal_dev /dev/sda10 mke2fs -J device=/dev/sda10 /dev/emcpowerl2 it works perfectly , but can I do the same whitout reformating the original FS; /dev/emcpowerl1 which is in

Hi,we have Centos 5.4 server and according to me we have strange problem. Disk size and other indormation like below.Normally,md2 partition should have 46GB free disk size but available value is zero.Why it show zero ? If you help me,I will be happy. df -h Filesystem Size Used Avail Use% Mounted on /dev/md1 19G 2.1G 16G 12% / /dev/md2 880G 834G 0

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'm setting up a new fileserver. It has two RAID controllers, a PERC 3/DI providing mirrored system disks and a PERC 3/DC providing a 1TB RAID5 volume consisting of eight 144GB U160 drives. This will serve NFS, Samba and sftp clients for about 200 users. The logical drive was created with the following settings: RAID = 5 stripe size = 32kb write policy = wrback read policy =

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

Hello all. I am currently using ext3 0.0.5d with great success. I am a bit conflicted about what to tell the system regarding my root filesystem however. I have my root filesystem configured and working as an ext3 filesystem, but it is/was not without some fraught. Using RedHat 7.0, if you simply create your journal on the root file- system, figure out it's inode number, issue a lilo -R

Hi All, Whenever an EXT3 partition is created some space is reserved for super-user, I used the mkfs.ext3 with option -m set to 0, but there is no effect it still reserve the space. How can i set the reserved-space to 0 or calculate the reserved-space in advance? Any suggestion/idea? Regards, -------------- next part -------------- An HTML attachment was scrubbed... URL:

I recently installed RedHat 8.0 on my computer but i discovered that i also needed to install windows for several programs that I still needed. I have two HDs, the RedHat install is on an 80Gb drive and the windows install is on an 8gb hard drive (which is the slave). I attempted to install windows on the slave but that is a no go so I powered down the computer and unhooked the ide cables

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

Hi all. I have a Dell SC440 running Centos 4.4. It has two 500GB disks in a RAID1 array using linux software raid (md1 is / and md0 is /boot). Recently the root file system was remounted read-only for some reason. The logs don't show anything unusual, presumably the file system was read-only before anythng was logged. Running dmesg showed this error repeated many times: EXT3-fs error (device

Hi, I am trying out ext3 with an external journal (on a battery backed RAM card). I use data=journal, and sync nfs writes go nice and fast :-) But.. I had to power cycle it (buggy VM.. grumble :-) and now I cannot get my filesystem back. It is only a test filesystem so I don't need the data. But I want this to work before I put real data on it. If I "fsck /dev/md1", it

I am using a kickstart file for CentOS 7 raid / --device=md0 --fstype="xfs" --level=1 --useexisting raid /home --noformat --device=md1 --level=1 --useexisting It is erroring out on the --useexisting. The exact text is: RAID volume "0" specified with "--useexisting" does not exist. What did I do wrong? Jerry
