Bug or not supported: Increasing array size after swaping disks

y_boonstra · 3. Januar 2015

Im in the last stage of increasing the raid size by swapping my 4 * 2Tb disks for 4 * 3Tb disks.

what i have done:
- turing off the server.
- swapping out 1 disk
- rebuilding the array

Reapeated the steps above for every disk. Then i tried to increase the filesystem size using the OMV menu ->File sysems->/dev/md0 and the clicking on resize. A windows pops up warning me if i realy want to increase it.. after clicking on Yes nothing happens the file system does not increase.

Can it that this way of increasing the filesystem size is not supported?

To finnish the job i used the following commands in a command prompt:

Code

mdadm --grow /dev/md0 --size=max
resize2fs /dev/md0

Im using OMV V1.8 and ext4 files system

I never tried that through the GUI.

The way you use it is actually working very well. If you asking about if it is supported I would say: Use at your own risk. If you do anything wrong, you risking all of your data. A good backup before would be a wise recommendation.

However you would need to grow your RAID in the GUI as well, but the grow function there is only used to grow it by adding additional disks to a RAID5 or RAID6.

Hope that helps.
