Can you replace a RAID drive with a bigger drive?

Can you replace a RAID drive with a bigger drive?

You can usually replace a failed RAID member with a larger drive, but not a smaller drive. The RAID will only use the space equivalent to the smallest drive in the array. You can also usually replace a failed RAID member with a drive that runs at a different speed than the other array members.

How do I replace RAID 1 drives with larger drives?

unplug your existing RAID 1, plug in new drives and make a RAID 1, then plug in one of each drive, clone 500 GB to 1TB, remove 500 GB and connect 1TB, and it could then rebuild. Then just go into Disk managment and expand the volume.

Can you expand a RAID array?

Note: Additional drives can be added to a RAID 0, 10, 5, or 6 array only. Other RAID levels cannot be expanded. Because of the very high I/O, the time needed and the vulnerability of the RAID array, Adaptec recommend to add a minimum number of drives needed for an expand.

Can you run different drives in RAID?

Must hard drives in a RAID array be identical? No. It is perfectly valid to use hard drives from different manufacturers, model numbers, sizes, and rotational speed (spindle speed or RPM).

Do RAID 5 drives need to be identical?

Do all drives have to be the same model and capacity for a RAID 5 array? The short answer is No, the drives don’t have to be exactly the same. The longer explanation is that for compatibility reasons, we usually recommend using the same model.

How do I upgrade RAID 5 drives to larger capacity?

Way 1. Upgrade RAID drive with existing free space

1. Right-click one of the RAID-5 volume slices, and select “Resize/Move Volume”.
2. In the pop-out window, drag the RAID 5 drive to increase its space using the unallocated space, then click “OK”.
3. Now you can preview the RAID 5 volume has been expanded.

Can RAID 1 be expanded?

To expand a RAID-1 volume: BREAK the mirror. Meaning, detach one of the drives using the controller software. Now, your 2-drive RAID-1 is running on one drive. The other is not part of the mirror and is “blank” for all intents and purposes.

Can you add more disks to RAID 5?

If all the RAID 5 dynamic disks are running out of disk space, you can add a new disk to extend the RAID 5. Note: The most important thing is to backup data first from your current RAID 5 disks to another external storage drive.

Can RAID 6 be expanded?

Expanding RAID 6 (Using 3x Drives), you require a minimum of 1x drive. Expanding RAID 50 (Using 6x Drives), RAID cannot be expanded. Expanding RAID 60 (Using 8x Drives), RAID cannot be expanded. If you want to expand RAID 00, 10, 50 or 60, you will have to first create a backup of your system.

Do hard drives need to be same size for RAID?

In a RAID 1 configuration, the size of target disk must be greater or equal to the one of the source disk. Therefore the capacity of the array will be same as the one of the smallest size in the group. The only exception is a spanned volume.

Can a RAID 10 / 50 / 60 drive be expanded?

For some reason, RAID 10/50/60 are not (and have never been) flexible on LSI-based controllers (OCE simply does not apply in any fashion). If you had any other RAID level, you could use OCE/Reconfigure to expand your array size using available space on the existing disks with an H700. 12-14-2013 01:57 PM

Is there a way to reconfigure RAID 10?

This option on the controller is called Reconfigure in the OpenManage software (Virtual Disks, in dropdown for RAID array) AND is the ONLY way it can be done (it cannot be done in the CTRL-R utility). Re-reading your post, seeing you have a RAID 10, let me emphasize that you cannot Reconfigure TO OR FROM a “nested” RAID level (10/50/60).

What are the names of the RAID 1 drives?

/dev/sde, /dev/sdf – are the two old 500GB drives, with 2 raid-1 arrays on them (md0 and md1) /dev/md0 (raid 1) made up of sde1 and sdf1, to be migrated to sda1 and sdb1 /dev/md1 (raid 1) made up of sde2 and sdf2, to be migrated to sda2 and sdb2

Can a RAID 1 drive be migrated to a SDB2 drive?

/dev/md1 (raid 1) made up of sde2 and sdf2, to be migrated to sda2 and sdb2 You’ll be able to get the drive designations in order by re-arranging the cables/drives/ports before starting the new procedure (Linux raid is smart enough to recognise its drives no matter the ports/connectors they’re on).
