Are you using hardware RAID 5 or software?First, you cannot boot from software RAID 5 - the /boot partition can be on a software RAID 1 set but not on RAID 0 or 5.If you are... [by TrevorH]
Anyone out there know about software RAID and LVM in grub2? I'm having real trouble getting it to work. I have an F19 system in a server, which has a reasonably large and fast RAID disk (software RAID0 over hardware RAID1 - this configuration chosen because the hardware RAID controller only supports levels 0 and 1). I'll call this RAID array md0 (that's what grub2 calls it).
I know Linux has great capabilities over the years of using it but I can't seem to find an exact name or setup for this scenario. I want to do Matrix RAID (that is not the correct general name but it was as close as I got) on two HDD. I want to put the OS in RAID 1 for redundancy and then have another partition or folder as RAID 0 for TV recordings both on two HDD.
I have software RAID on Ubuntu 10.10 with currently disabled hardware RAID controller, server has 2*500GB in RAID 1 drives for OS and 3TB*4 in RAID 1 for storage. What do i want, create hardware raid at least for storage w/o loosing data, or best option to add two new 3TB drives and create hardware RAID 10.
Can I have software RAID for OS and hardware raid for storage ?
Does anyone know if Fedora 12 recognises a RAID array on the ICH9R raid chipset? In the past I've found that most on board raid chipsets are software or bios assisted software based and typically linux can only see thier component drives, not the array itself.
There was RAID-1 device created of two partitions of the similar size on two disks. Disks are not of the same size and there are other (non-RAID) partitions.
During clean install of 13.04, I haven't touched those two partition (left them unformatted and assigned to anything) and now have newly installed system with old (non-RAID) partition regularly accessible.
We have a Ubuntu 12.04 LTS server which is configured with a 2 disk software 1 RAID (mdadm). The disks are 3TB and partitioned with a 1MB GPT partition and with the remaining assigned to the RAID. The RAID partition is then allocated as LVM Volume Group and hosts three logical partition for the /boot, /, swap. Following the system being built we tested it by removing a disk and all worked well.
