I was wondering if it is a good idea to replace a hard drive in a (fairly) system-critical database server after a certain number of years of use, before it dies. For example, I was thinking of replacing a hard drive after 3 years of use. Since I have many hard drives across servers, I could stagger which hard drives are replaced.
Any of you do this?
I am using Ubuntu 12.04 LTS. My hard drives usually comes as: sda, with 'sudo blkid' and if I plug-in any USB drive, they comes as: sdb, sdc etc; after sda. That's fine!!!
But problem arises after I restart my laptop with connecting those USB drives. They alter and comes first and hard drive goes to the end, like: 'sudo blkid' shows, sda, sdb for USB drives and sdc for hard drives.
I am a novice user who upgraded to 11.10. In my previous version of Ubuntu, icons of my external drives(2) were visible and I could mount and navigate these drives. I cannot locate my external hard drives with 11.10. I have searched the questions with similar titles and have not found a solution.
The command: sudo fdisk -l does list both external hard drives.
I recently converted my home media server from Windows Server 2008 to Ubuntu 11.10. Right now, there is a single WD20EARS 2 TB hard drive formatted as NTFS that's about to run out of space.
I'd like to purchase a few extra drives (the case can hold an additional two).
I am trying to help out a friend with an odd issue. He has two external hard drives he was using as storage on a I-Mac. He had several terabytes of information on each drive, then one day the drives didn't show up on his mac.
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.
How do I boot with two identical drives?
I have two identical Western Digital WD6400AAKS SATA-II 7200 rpm 640 GB hard drives.
One of the drives is an internal drive on one machine. The second is available with a mobile drive bay.
I can't boot the system with both drives installed.
I have a 4 scsi drives in a RAID 5 configuration and one of them has failed leaving the server in an interim recovery configuration.
Hi,
I need som advice. I have a CentOS machine at home serving mainly as a fileserver. It has a few hard drives for this purpose alone - mounted as /mnt/media0, /mnt/media1, /mnt/media2.
What I'd like is to have all of these drives act as one big "file pile" - but I don't want raid or jbod because I don't want one disk failure to kill the whole "array".
