Recovering the OS from software RAID HDD crash with rPath (or RHEL/CentOS/Fedora)?
Newb here.
I'm trying to build a home NAS using openfiler. I don't have a hardware RAID so I have set up a software RAID. So my disks are /dev/sda /dev/sdb /dev/sdc /dev/sdd df -h Filesystem Size Used Avail Use% Mounted on /dev/md3 2.0G 693M 1.2G 37% / /dev/md0 251M 19M 219M 8% /boot tmpfs 1.9G 0 1.9G 0% /dev/shm < (swap?) /dev/md1 745M 17M 690M 3% /var/log /dev/md0 is raid 1 mirrored using sda1 and sdc1 /dev/md1 is raid 1 mirrored using sda2 and sdc2 swap is raid 1 mirrored using sda3 and sdc3 /dev/md3 is raid 1 mirrored using sdb1 and sdd1 I set that up using this doc https://forums.openfiler.com/viewtopic.php?id=2501 and this for reference http://www.redhat.com/docs/manuals/l...ware-raid.html So you guys probably can't speak for OpenFiler, so just tell me if this holds true for RHEL/CentOS. Lets say the sda drive dies. The info is mirrored on sdc. I've done some reading and I just want to make sure that this sounds right. Using the instructions here: http://www.linuxquestions.org/questi...e-raid-527345/ 1. Partition /dev/sda the same as /dev/sdc: sfdisk -d /dev/sdc | sfdisk /dev/sda 2. Add the partition to the array: mdadm /dev/md0 --add /dev/sda1 3. mdadm /dev/md1 --add /dev/sda1 4. mdadm /dev/md3 --add /dev/sda1 (what about swap?) |
