Hi All. I have a server which uses RAID10 made of 4 partitions for / and boots from it. It looks like so: mdadm -D /dev/md1 /dev/md1: Version : 00.90 Creation Time : Mon Apr 27 09:25:05 2009 Raid Level : raid10 Array Size : 973827968 (928.71 GiB 997.20 GB) Used Dev Size : 486913984 (464.36 GiB 498.60 GB) Raid Devi...

I just created a 4 drive mdadm --level=raid10 on a centos 4.8-ish system here, and shortly thereafter remembreed I hadn't updated it in a while, so i ran yum update... while installing/updating stuff, got these errors: Installing: kernel ####################### [14/69] raid level raid10 (in /proc/mdstat...

So after troubleshooting this for about a week, I was finally able to create a raid 10 device by installing the system, copying the md modules onto a floppy, and loading the raid10 module during the install. Now the problem is that I can't get it to show up in anaconda. It detects the other arrays (raid0 and raid1) fine, but the raid10 array won't show up. Looking through the logs (Alt-F3), I see the following warning: WARNING: raid level RAID10 not supported,...

I would like to set up CentOS on 4 SATA hard drives that I would like to configure in RAID10. I read somewhere that Raid10 support is in the latest kernel, but I can't seem to get anaconda to let me create it. I only see raid 0, 1, 5, and 6. Even when I tried to set up raid5 or raid1, it would not let me put the /boot partition on it, and I though that this was now possible. I...

...SATA HDDs. The plan is to use RAID-10 as a nice combo between data security (RAID1) and speed (RAID0). However, I'm finding either a lack of raw information on the topic, or I'm having a mental issue preventing the osmosis of the implementation into my brain. Option #1: My understanding of RAID10 using 4 drives (now known as a,b,c,d) is: a+b - RAID1 (md0) c+d - RAID1 (md1) md0+md1 - RAID0 (md3) This is of course simplified as /boot needs to be on RAID1 (last I checked Grub couldn't boot from anything other than RAID1). Option #2: I've also found the kernel provides a direct meth...

hi guys, gals do you know if conversion from lvm's raid10 to raid0 is possible? I'm fiddling with --splitmirrors but it gets me nowhere. On "takeover" subject man pages says: "..between striped/raid0 and raid10."" but no details, nowhere I could find documentation, nor a howto. many thanks, L.

Hi! The problem is that the BTRFS raid10 filesystem without any understandable cause refuses to mount.

Hi all, I have a question about replacing a drive in raid10 (and linux kernel 3.8.4). A bad disk was physical removed from the server. After this a new disk was added with "btrfs device add /dev/sdg /btrfs" to the raid10 btrfs FS. After this the server was rebooted and I mounted the filesystem in degraded mode. It seems that a previous started bal...

Does anyone know of a card that actually works with CentOS 4 that supports Raid10? I don't think CentOS support software raid 10 from the installer.

...t device was failing (It was very old.). I attached a new drive to the hot-swappable SATA slot on my computer, partitioned it with GPT, and ran partprobe to detect it. Next I attempted to add a new device, which was successful. However, something peculiar happened: ~: btrfs fi df /var/media/ Data, RAID10: total=2.33TiB, used=2.33TiB Data, RAID6: total=72.00GiB, used=71.96GiB System, RAID10: total=96.00MiB, used=272.00KiB Metadata, RAID10: total=4.12GiB, used=2.60GiB I don't know where that RAID6 file system came from, but it did not exist over the weekend when I last checked.

I have been reading lots of stuff but trying to find out if a raid10 2drive setup is any better/worse than a normal raid 1 setup....I have to 1Tb drives for my data and a seperate system drive, I am only interested in doing raid on my data... So i setup my initial test like this.... mdadm -v --create /dev/md0 --chunk 1024 --level=raid10 --raid-devices=2 /dev/sdb1...

Hello, On my system with a Intel SCU Controller and a Raid 10 System it is not possible to install this Raid10. I have tested this with a CentOS 7 and Opensuse all found my Raid but with CentOS 8 this is broken? I found on start the Installation a Error from mdadm that ist all. Now I download and Test the Stream iso? and hope ..... -- mit freundlichen Gr?ssen / best regards G?nther J, Niederwimmer

We have DELL R910 with H800 adapter in it. several MD1220 connect to H800. Since MD1220 have 24 hard disks in it. When I configured RAID10, there is a choice call 'single spanned virtual disk" (22 disks). Can anyone tell me how "single spanned virtual disk" work? Any document relate to it? Thanks.

Hello! I have a 1 TB ext4 drive that''s quite full (~50 GB free space, though I could free up another 100 GB or so if necessary) and two empty 0.5 TB drives. Is it possible to get another 1 TB drive and combine the four drives to a btrfs raid10 setup without (if all goes well) losing my data?

...s - fileserver, mailserver, webserver, virtual server, and whatever else pops up. Current incarnation of the machine, after the last rebuild, is an AMD Opteron 4180 with a Supermicro MB using ATI SB700 chipset - which means it supports SATA 3.0. Current storage is one o/s drive, and a 4-drive RAID10 array. The RAID10 is using the Linux softraid via mdadm. The drives are Seagates - ST3160811AS. So it's 320GB of storage, and SATA 1.5. I'm seeing some warnings & errors in my logs & dmesg - and Google tells me this can the result of several factors, including the hard drives...
