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 Devices : 4 Total Devices : 4 Preferred Minor : 1

Hello list, recently reformatted my home partition from XFS to RAID1 btrfs. I used the default options to mkfs.btrfs except for enabling raid1 for data as well as metadata. Filesystem is made up of two 1TB drives. mike@mercury (0) pts/3 ~ $ sudo btrfs filesystem show Label: none uuid: f08a8896-e03e-4064-9b94-9342fb547e47 Total devices 2 FS bytes used 888.06GB devid 1 size 931.51GB used

I am trying to install Centos 7 on a couple 4TB drives with software raid. In the Supermicro bios I set UEFI/BIOS boot mode to legacy. I am using the Centos 7 minimal install ISO flashed to a USB thumb drive. So I do custom drive layout something like this using sda and sdb. Create /boot as 512 MB XFS raid1 array. Create SWAP as 32 GB SWAP raid1 array. Create / on 3.xxx TB XFS raid1 array.

I''ve had a go at determining exactly what happens when you create a filesystem without enough devices to meet the requested replication strategy: # mkfs.btrfs -m raid1 -d raid1 /dev/vdb # mount /dev/vdb /mnt # btrfs fi df /mnt Data: total=8.00MB, used=0.00 System, DUP: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=153.56MB, used=24.00KB Metadata:

Hello, I''m testing Btrfs RAID1 feature on 3 disks of ~10GB. Last one is not exactly 10GB (would be too easy).

hi all! back in Aug several of you assisted me in solving a problem where one of my drives had dropped out of (or been kicked out of) the raid1 array. something vaguely similar appears to have happened just a few mins ago, upon rebooting after a small update. I received four emails like this, one for /dev/md0, one for /dev/md1, one for /dev/md125 and one for /dev/md126: Subject: DegradedArray

I plan to upgrade an existing C7 computer which currently has one 256 GB SSD to use mdadmin software RAID1 after adding two 4 TB M2. SSDs, the rest of the system remaining the same. The system also has one additional internal and one external harddisk but these should not be touched. The system will continue to run C7. If I remember correctly, the existing SSD does not use a M2. slot so they

hi, it's been a few weeks since rhel/centos 5.4 released and there were many discussion about this new "feature" the weekly raid partition check. we've got a lot's of server with raid1 system and i already try to configure them not to send these messages, but i'm not able ie. i already add to the SKIP_DEVS all of my swap partitions (since i read it on linux-kernel list

Somewhere, mdadm is cacheing information.

I have configured 2x 500G sata HDD as Software RAID1 with three partitions md0,md1 and md2 with md2 as 400+ gigs Now it is almost 36 hours the status is cat /proc/mdstat Personalities : [raid1] md0 : active raid1 hdb1[1] hda1[0] 104320 blocks [2/2] [UU] resync=DELAYED md1 : active raid1 hdb2[1] hda2[0] 4096448 blocks [2/2] [UU] resync=DELAYED md2 : active raid1

...ns within the installer then appear to allow me to create my LVM with Raid1, but the /boot and /boot/efi are then outside the Raid. 4. It looks like I can set the /boot partition to be Raid1, but then it is a separate Raid1 from the LVM Raid1 on the rest of the disk. Resulting in two separate Raid1s; a small Raid1 for /boot and a much larger Raid1 for the LVM volume group. I finally manually setup a base partition structure using GParted that allowed the install to complete using the format below. sda (3TB) sda1 /boot fat32 500MB sda2 /boot/efi fat32 500MB sdb (3TB) sd...
