The vast majority of 2.5" drives you'll see for ProLiants will fit in systems from G5-G7. However, Gen8 and newer HP servers use a different disk form-factor. The OP should post a photo or part or part number of the drive in question. G5 disk on left. Gen8 disk on right.
Hard drives do have a multitude of error correction methods in place to prevent data corruption. Hard drives are divided into sectors, from which some may become completely unwritable / unreadable or return wrong data through data corruption - let's call the first bad sector corruption and the latter silent data corruption. Bad Sector Corruption The first ...
I hate when people say that the server is "down" or "crashed". What exactly is wrong with it? The HP Smart Array E200i controller appeared in HP ProLiant G5 servers from 2006-2008. The B320i controller is featured in low-end HP ProLiant Gen8 servers, which were introduced in 2012. The disks have different drive carriers and the controllers have different ...
Resilvering (and scrubbing) involves walking the entire B-Tree of the pool, and re-silvering blocks that would have been on the missing disk. Without walking through every single txg in the tree, it cannot know which blocks would have been on the missing disk, hence it scans the entire metadata universe for the pool. It doesn't necessarily read all the ...
Yes it's fine. Please see: Directly Formatting a Device on a Linux System The best practices around this have changed over time. If this is a virtual machine, the case for not using partitions is more compelling.
Looks like you did an mdadm --create on "Creation Time : Thu Jun 11 23:21:12 2015", that could be a problem if you used the wrong parameters. What command line did you use? Also when the mount fails what is reported by... dmesg | tail And it's a good idea to check the SMART data on the drives to see if they are healthy. Don't despair. I often work on ...
For the first question: When I try to mount the /dev/sda1 hard drive with the command mount -o barrier=0 /dev/sda1 it gives me this message: mount: can't find /dev/sda1 in /etc/fstab or /etc/mtab How can i fix this, so i can backup all of my stuff? The answer is that mount looks for mount points in either /etc/fstab or /etc/mtab, but none is ...
HP's official statement on moving hard drive. Moving drives and arrays You can move drives to other ID positions on the same array controller. You can also move a complete array from one controller to another, even if the controllers are on different servers. Before moving drives, you must meet the following conditions: • If moving the drives to a ...
Full reinstall is IHMO safer option, Windows most probably will give you BSOD error 0x0000007B @ boot due: incorrect disk controller driver, lack of disk controller driver, https://support.microsoft.com/en-us/kb/324103 Full reinstall and full array sync is also better, because it'll help you verify the hardware - disks, memory and its stability.
Write the complete or partial WWID or WWN of the disk on its label or record it somewhere in a slot map. Also see: Identify Disks on SuperMicro server running FreeBSD
Have you tried using the diskinfo command? http://docs.oracle.com/cd/E23823_01/html/816-5166/diskinfo-1m.html
Certain system files are not moved by MS defrag and deliberately spread on the disk. You need to use a bootable 3rd party defrag tool to do an offline defragmentation. Just google defrag bootable
