Posted: Sun Aug 11, 2013 12:05 am Post subject: Need advise on what to use for raid |
|
|
I been trying to mount my raid 1 drives for about a week now and don't know what way to turn. I have 2 - 2TB dives with 3 partitions for mirrored storage that I want to access from windows or linux. Can someone tell me what's the best way to do this and which packages to use. In the past I just made the partitions in windows the ran dmsetup -ay added devices to dmtab and fstab and i was done. Now dmsetup has changed and i can't get linux to make the devices to mount them. I've tried lvm2 dmraid and mdraid - nothing works. The system is set to boot uefi only and gpt seems to be part of my headache.
what i'm trying to get :
sdb1, sdc1 > raid1
sdb2, sdc2 > raid2
sdb3, sdc3 > raid3
my setup:
Code: | Number Start End Size File system Name Flags
1 1049kB 316MB 315MB ntfs Basic data partition hidden, diag
2 316MB 420MB 105MB fat32 EFI system partition boot
3 420MB 555MB 134MB Microsoft reserved partition msftres
4 555MB 158GB 157GB ntfs Basic data partition
5 158GB 158GB 134MB ext2 Basic data partition boot
6 158GB 159GB 1049MB linux-swap(v1) Basic data partition
7 159GB 316GB 157GB ext4 Basic data partition
8 316GB 395GB 78.6GB Basic data partition
9 395GB 474GB 78.6GB Basic data partition
10 474GB 945GB 472GB ntfs Basic data partition
11 945GB 972GB 26.2GB ntfs Basic data partition hidden, diag

Code: |
00:1f.2 SATA controller: Intel Corporation Lynx Point 6-port SATA Controller 1 [AHCI mode] (rev 04)
06:00.0 SATA controller: Marvell Technology Group Ltd. 88SE9172 SATA 6Gb/s Controller (rev 11) |
my OS drive is connected to the intel sata controller and the raid drives are connected to the marvel sata controller. I don't know if where it connected matters or not and i'm confused if this is software or fake raid. |

Likely you are using fakeraid if you set it up using the card's BIOS. Linux can detect many of these fakeraid and set them up for you.
You don't need to use fakeraid at all (which is handled by device mapper). You can just use software MDRAID instead of fakeraid in which you would use mdadm to administrate them instead of dmsetup. You should disable RAID in BIOS to use MD software RAID.
Now I don't know why it stopped working. I have not had much experience working with dmraid unfortunately, but I would venture to guess that if the BIOS firmware on the fakeraid board doesn't detect the raid, then dmraid won't play with it either. _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD

Thanks for the reply, I forgot to mention this is a new computer. Device mapper is still working on my older computer just the commands have changed and that one is allready setup. The older comp is also setup as mbr instead if gpt

I believe i have a bad controller. when you mentioned the bios settings i realised i never changed them from default. When I changed the setting from ahci to raid it hangs at the post screen for like 5 minutes and ctl+m doesn't give me the raid setup utility. So now I'm waiting for gigabyte tech support to respond (ill be back ) |

maybe you need to blank the drives before running the util _________________ Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein |
