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.
I'm currently hosting a game server with the current specification
E1230
32GB Ram
2x 1Tb SATA
Windows 2008 server
SQL Server 2012
Databse size is 10Gb
Number of players 1k
The problem at first I had I/O bottleneck with 2x1Tb as I was using the default SQL configuration and all the files .mdf and .ldf were stored in default C:/SQLSERVER
Then I added 2 more 1 Tb disks and I isolated .mdf and .ldf
I have a HP Proliant DL 380 G7 Server with a RAID 5 that has 2 failed disks.
My Question is, can i reduce the array to 3 hard disks that are remaining to work with them alone? Can I do this without loosing any data in the hard disks?
I want to spin down some hard-disks when they are idle. So I used hdparm package. In the /etc/hdparm.conf I added following lines:
command_line {
hdparm -Ss 241 /dev/sda }
My intention was to spin down hard disk after 30 minutes of idle time. However, my problem is, how I know for sure whether hard disk has spun down (assuming that it had exceed idle time of 30 minutes)??
Any ideas? Tips??
For some unusual reason my disks in my RAID 5 config have started failing. Now they haven't all failed at once, and i they did I would be looking at the RAID controller as the cause. I noticed the other day that two or three disks had an orange light.
This prompted me to take some drastic action because I wanted to upgrade the disk sizes anyway.
Hello,I have a server wich is connected to an iSCSI storage and gets harddisks from this storage.Sometimes I have to add new disks to this server.Everytime I add a disk and ... [by akyl]
I currently only have remote access to this CentOS box, I need to move /var form the primary RAID to a new set of disks that was installed with more space, My current thoughts on how to accomplish this is to temporarily mount the new RAID to /tmp/var. rsync everything from /var to /temp/var then modify the fstab to point /var at the new disks.
Here is my question.

I have two identical 2 TB eSata external harddisks. Until recently I had them configured as a RAID-1 array.
I have to check the raid configuration on a server running Windows server 2003.
I know how check if the RAID is hardware, but how if it's a software RAID?
If the type of all harddisks is Basic, is it possible to exclude a software RAID?
