I was switching the disk drives in my server, running RAID 6 on 5 disks on a 3ware 9650SE controller, for newer disks and have run into a problem.
The two first disks went fine, I took out one disk and inserted a new one, let the array rebuild and repeated for disk 2.
When booting after switching the 3.
Hi guys,
With the hardware raid controller ive got at the moment to have all my disks show as separate I need to set the raid controller, to have 4 Virtual Disks all in raid 0
I'm going to be doing alot of copying to the server some of the files be rather quite large from different servers.
I have 22 disks and would like to create a Raid 10. Unfortunately my raid controller (MegaRAID SAS 9260-8i) is only capable to handle 8 arrays within a RAID 10. Because of that I could only use 16 disks in a 2 disks per array configuration.
I have a GIGABYTE motherboard GA-P35-DS3 with onboard RAID-1 controller. When I replace one disk, how does the RAID controller detects that there is an empty disk, that has to be filled with the old data?
I want to install newer disk with a higher capacity. Can I use a disk image tool like Acronis to copy the disk content from one of the old disks to the new harddisk?
I dont have extra server. Server is in IDC.
I have centos 5 OS installed.
with RAID bus controller: Adaptec AAC-RAID (rev 02) controller (Adaptec 4000SAS)
4 disks x 74gb sas 15k
no LVM
filesystem EXT3
how to migrate without pain?
I want to set up software RAID-1 on my Ubuntu system, and found this example of an /etc/raidtab:
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
persistent-superblock 1
device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1
I would however like the path to the raid device to be /raid.
I have Dell Poweredge R710 server with PERC H700 Integrated RAID controller. Currently there are 4 SAS 300GB disks in RAID-10 array exposing single volume of 600GB. Server is running VMware ESXi 5.1.
I have 4 new SAS 300GB disks that I would like to add to this server to gain ~ 1.2 TB RAID-10 volume.
I wonder if I can do this expansion without loosing data on existing disks?
Hi guys!
A few days ago, I started upgrading my raid (raid 5) from using 4x1TB to 4x3TB. Never done this before, so it took a while. I replaced the disks one by one and rebuilt the raid in between as I read in some guide. All worked fine, except fdisk complained a little bit about my disks being very large. Didn't think much of it at the time.
I have a beginner question about using software raid on Ubuntu and what the smartest way is to build the hardware for a home-file-server.
My plan is to have a server with one system disk(SSD 60GB) and 3-6 2TB disks in a software raid 5 or 6 or 10(havent decided yet...) using mdadm. So my idea is to not include the SSD drive in any raid, and just run it standalone with Ubuntu server.
