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 ?
Hi,I have a RAID controller (SATA x4 RAID DELOCK 70154) and I have the following problem.The RAID configuration (just as BIOS) I have set up with two identical drives RAID 1... [by puciol86]
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.
When Ubuntu 9.10 landed, I installed it and saw the partitioner listed my drives in a weird fashion. I have 4 drives in my system - two 500gb drives, two 250gb drives. The 250s appear as nvidia-mapper-device, or something like that. I was told this was fake raid. Since Ubuntu 9.10 gave me a lot of trouble, I used 9.04 and never "fixed" this issue.
I have a question about speed performance with two separate SSD drives comparing them to RAID mirror array.
Hey Ubuntu Forums, long time no see.
So i'm trying to set up a RAID, but i'm a bit inexperienced and i'm not sure if the configuration i want to achieve is possible. I was hoping someone more knowledgeable could point me in the right direction.
I have one 2TB and two 1TB drives that i would like to configure in such a way that would be equivalent to two 2TB drives in RAID0.
So here is what I have currently:
8 SAS Drives total
6 Drives setup as RAID 5 as Virtual 1.
1 Drive setup as Hot Spare.
1 Drive in Ready state that is not part of the RAID and is not set as a hot spare.
Basically, everything on this server is setup on the RAID 5 as one virtual disk (OS, data, etc) and partitioned out. I want to separate things out a bit.
Hi all,
I'm setting up a backup server (yes, I know raid isn't a backup).
I purchased 4 3TB drives, and I was thinking, is there any point to the performance boost Raid 10 gives over Raid 6? All the accesses will be remote, so even with Gigabit ethernet, I'll max out at 125 MB/s (theoretical).
I am working on decommissioning an old server for a client. The server is an older Dell PowerEdge 1600sc with four SCSI drives. Two are stand-alone, and the other two are in RAIDx (not sure the actual RAID id). It does not have an integrated RAID controller (nothing under integrated devices in the BIOS related to RAID), the client has a PowerEdge Expandable RAID controller PCI card for that.
