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 device=/dev/hda5 /dev/md1 Now, here's the fun part. I've already put data on /dev...

...At this point drive c has 250gb worth of partioned space in raid/lvm. I then add a 500gb drive b and repeat above pulling out drive a. Now I have two 500gb drives (b and c) with 250gb worth of partitions mirrored. I am thinking I would next forget about md0 (the boot part) and concentrate on the md1, where the whole system lies. # mdadm --grow /dev/md1 --size=max I believe this will grow out the size of md1 to fill the 500gb of the drive. I would then wrestle with expanding the LVMs that fill the md1 up as I wish. After that, I would add drive 'a' 500gb to the mix by cloning the pa...

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\"...

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 md device, partitioning it and create fs on each partition created on md device: m...

I have noticed that when I do software raid installed (RAID1) that I reboot and one of the first things it says is md1 is not in sync doing background reconstruction... md0 is my /root partition md1 is my /home partition why would md1 not be in sync after an install. Jerry

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, ls /dev/md* shows only md0, which worked fine. I do have the 'raid1' kernel module loaded. What am I missing? Do I need to create the nodes manually now? thanks -S

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 lo...

I have a machine on CentOS 5 with two disks in RAID1 using Linux software RAID. /dev/md0 is a small boot partition, /dev/md1 spans the rest of the disk(s). /dev/md1 is managed by LVM and holds the system partition and several other partitions. I had to take out disk sda from the RAID and low level format it with the tool provided by Samsung. Now I put it back and want to reassemble the array. Machine boots fine from...

Hi. CENTOS 7.6.1810, fresh install - use this as a base to create/upgrade new/old machines.
