Hello list, I'm trying to install CentOS 5.2 on LVM on a SW-RAID level 1, but I'm unable to understand how to use the installer correctly. What I'm trying to do is emulate something I've already done with another distro where: sda5 \ RAID1 --> /boot sdb5 / sda6 \ RAID1 --> LVM --> /root, /home, /usr, /var... etc. sdb6 / I've succesfully

I am looking into setting up Xen 4.0 on a simple dual-boot Windows/ubuntu laptop with the following partitions: | Device Boot Start End Blocks Id System | /dev/sda1 * 1 223 1782784 7 HPFS/NTFS | /dev/sda2 223 21713 172624888 7 HPFS/NTFS | /dev/sda3 35854 38914 24576344 7 HPFS/NTFS | /dev/sda4

We're getting the below errors about once a day on a system we're trying to set up with RedHat 7.3. This has happened to multiple filesystems on multiple physical and logical disks (basically we've got 4 drives as 2 sets of RAID 1 arrays, details below). Until a week ago, this box was a high-volume IMAP server running RedHat 6.2 with uptimes in the 200-day range, so I don't

Thanks for your help Sean, did all the steps you mentioned. One thing I don't understand, when partitions are created, why does Linux number it awkwardly? For example, I created 1 Primary partition of 10% disk, then created 1 Extended partition of 90% disk. Inside that extended partition, I created 3 logical partitions 33% each. It went numbering sdb1, sdb5, sdb6 and sdb7. Where's the hell

I'm trying to install extlinux on my dual-booting computer, but when i try cat mbr.bin > /dev/sda the computer boots windows (it doesn't even come up with the extlinux menu). My partition setup is as follows: /dev/sda1 -> NTFS (Windows) /dev/sda5 -> Linux Swap /dev/sda6 -> Linux Root (/) /dev/sda7 -> Linux Home (/home) Now I presume that mbr.bin calls the bootsector of

Hi, I'm using virt-resize to expand the primary partition (C:) in a Windows 2003 image. The command works fine but after expanding, when I boot into Windows 2003, all the other partitions (D:, E:, and F:) are lost. After using the disk management tool within Windows 2003, I can re-label the above three partitions and all the files are still there. But it is really annoying because every

Hey, I installed 2 new data servers with a big (12TB) RAID6 mdraid. I formated the whole arrays with bad blocks checks. One server is moderately used (nfs on one md), while the other not. One week later, after the raid-check from cron, I get on both servers a few block_mismatch... 1976162368 on the used one and a tiny bit less on the other...? That seems a tiny little bit high... I do the

I apologize if the question has been posed before, but I did not find any similar posts by browsing or searching through the forums. Here it goes: I have been using Gentoo Linux for a year now, and never have I had a problem I couldn't solve. However, not long ago I bought a 1 TB hard disk which I divided into 7 partitions: /boot, (swap), /, /var, /tmp, /usr and /home (yes, that's FreeBSD

Hi everyone, I made a utility tool for dm-ioband version 0.0.4, named iobandctl. It enables you to easily apply I/O bandwidth control to an entire disk, and manage it. It helps you set the percentage of bandwidth to give each partition, and each user, process, group, or cgroup. (You are not able to use cgroup support yet, because the dm-ioband patch to enable cgroup support
