Apologies if you get this twice - the first one didn't seem to make it... Hi Guys, I have just replaced a faulty Max...woah, wait...this one's a Seagate... IDE hard disk but I cannot remake the software raid pair. The currently running disk is hda and I am trying to add back hdg - both are master drives on separate controllers. I have run fdisk on hdg and created the same partition

Hello Everyone I have a remote CentOS 6.4 server (with KVM access), when I received the server it was running with LVM on single disk (sda) I managed to remove LVM and install raid 1 in sda and sdb disks the mirroring is working fine, my only issue now is that everytime I reboot the server I got the grub command line and I have manually boot using comand grub> configfile

Hi, I have two 320 GB SATA disks (/dev/sda, /dev/sdb) in a server running CentOS release 5. They both have three partitions setup as RAID1 using md (boot, swap, and an LVM data partition). # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb1[1] sda1[0] 104320 blocks [2/2] [UU] md1 : active raid1 sdb2[1] sda2[0] 4192896 blocks [2/2] [UU] md2 : active raid1 sdb3[1]

Hi, I have 2 identical xSeries 346 with 2 identical IBM 72GB scsi drive. What i did is install the centos 4.2 serverCD on the first IBM and set the HDD to raid1 and raid0 for swap. Now what i did is get the 2nd HDD in the 1st Server swap it with the 1st HDD in the 2nd Server and rebuild the Raids. The 1st server rebuild the array fine. My problem is the Second server, after rebuilding it and

Hi, Today I replaced grub(1) with syslinux on my laptop, after rebooting to syslinux and selecting kernel I got massive freeze along with colorful output to screen - http://i.imgur.com/lFjFc.jpg I think I tried everything, even doing esc and writing after boot: /bzImage-3.1.0, after enter I had the same freeze with the same screen artefacts. How I installed extlinux: mkdir /boot/extlinux

I am running software RAID1 on a somewhat critical server. Today I noticed one drive is giving errors. Good thing I had RAID. I planned on upgrading this server in next month or so. Just wandering if there was an easy way to fix this to avoid rushing the upgrade? Having a single drive is slowing down reads as well, I think. Thanks.

Hi All, I have what I believe to be a pretty basic LVM & RAID setup on my CentOS 5 machine: Raid Partitions: /dev/sda1,sdb1 /dev/sda2,sdb2 /dev/sda3,sdb3 During the install I created a RAID 1 volume md0 out of sda1,sdb1 for the boot partition and then added sda2,sdb2 to a separate RAID 1 volume as well (md1). I then setup md1 as a LVM physical volume for volume group 'system'. I

Hello, I have two disks sda and sdb. One of the was broken so I have changed the broken disk with a working one.

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

Does anyone know how anaconda partitioning enumerates disk partitions when specified in kickstart? I quickly browsed through the anaconda installer source on github but didn't see the relevant bits. I'm using the centOS 6.10 anaconda installer. Somehow I am ending up with my swap partition on sda1, /boot on sda2, and root on sda3. for $REASONS I want /boot to be the partition #1 (sda1)

Hi Niki, md127 apparently only uses 81.95GB per disk. Maybe one of the partitions has the wrong size. What's the output of lsblk?

Hello all, I am attempting to install CentOS 5.5 on a recently donated home server (was Windows). I've tried installing twice; first, separating /boot, swap, /, /var, /usr and /home into different partitions, the second time choosing default layout. Both times have resulted in "GRUB Hard Disk Error" upon boot. About the hard disk, it is a Seagate SATA drive. I do not have another

Hello fellow CentOS'ers- I've got a system running CentOS 5.0. The motherboard has two onboard SATA ports with two drives attached. I installed the system on a RAID1 setup. However, I'd like to add a hotspare disk to the array. Since there are no additional SATA ports, I've installed an additional controller. After partitioning, the additional drive was easily and successfully

- Ahh OK now I see why I was confused. The originally posted partition map uses cylinders as units, not LBA. I missed that. Cylinder 1 is the same as LBA 63. And that is sufficiently large for a GRUB legacy stage 2. - OK this is screwy. Partitions 1 and 3 on both drives have the same number of sectors, but partitions 2 differ: /dev/hde2 401,625 975,691,709 975,290,085 fd Linux
