[Hardware] - [Linux RAID]. In the table, open one of the devices, like /dev/md0.
In the "RAID device options" , see "Status: Clean". Go back and click /dev/md0 again.
The status is now "Status: active". The status keeps alternating between the two.
What does the /proc/mdstat file contain on your system?
Hi, thanks for your reply, here's my file:
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md1 : active raid1 sdb2 sda2
10747392 blocks [2/2] [UU]
md0 : active raid1 sdb1 sda1
477636416 blocks [2/2] [UU]
unused devices: <none>
You seem to have CSS turned off.

That looks clean to me. If you check that file a few times a few minutes apart, does it change?
I have been checking it frequently over the last month or so. I have also tried your suggestion, and checked it every five seconds or so - over a couple of minutes. It stays the same. I must say that is quite a relief :) But it keeps being strangely changing in Webmin. Does webmin interpert the information or does it just display?
It got noticed because it changes in such rapid succession.
It's not bothering me, it isn't broken, but it is really noticeable.
I'm using Ubuntu Linux, 9.04 x64
I looked at this some more, and was actually able to reproduce the issue you saw.
Webmin gets the state from the command " mdadm --detail /dev/md0" , and I found that this does indeed iterate between "clean" and "active".
So it looks like Webmin is doing the right thing. My guess is that "clean" means the RAID is fully in sync, and "active" means it is copying data to some disk.
Allright! Thanks for looking into it in such detail, it's much appreciated.
