Hello,

I wanted to know if there is a guide that can explain how to safely add additional drive to an Existing RAID5 array?
I need to add additional 3TB drive and my Linux skills are still not that great.

Thank you

Hi,

I got an Email regarding Degraded Array.
AS you can see, it's expecting sdb as part of the RAID.

On the other hand, In the System Info it seems that now the drive is sdf.

Is there an easy way to fix it without formatting sdf and doing recovery?

Thank you

Hello,

I have today RAID 5 connected to a SATA 3 controller which is connected via PCI.

I think that this card is not good since my raid breaks every few weeks.

I want to connect my DISKS directly to the Mother board which is SATA 2.

The question is will my RAID 5 will continue to work?

Apparently there were 2 folders sized 0. This caused the fsck to fail because they were not correctly. By tweaking the folders with chown and chmod I could create and remove a folder in them and size became valid. Then ran fsck again and FS repaired.

I still have an issue now with a message regarding Spare drive

Hi, I boot with system rescue cd and ran the fsck command. It also didn't fix the issue. Any other options I can try?

Hi,

I'm not familiar with this tool, should I downoload: SystemRescueCD 4.7.3 from https://sourceforge.net/projects/systemrescuecd/
and boot it from USB?

Is there any specific tool recommended?

danieliod · 21. Juni 2016

The results are still the same, there are 2 issues which couldn't be resolved.

What else can I try?

Hi,

From some reason during the RAID Repair my Server shutdown.
When it boot up again, it ave an error regardign the RAID filesystem and ask for Manual intervantion.

I executed:

Code

fsck.ext4 /dev/md127

when it finished it gave a warninig that there still File system issues.
I ran it again and it gave the same error, I restarted and run it again and still the same error.
Now every time I want to restart the server I need to press Contorl+D.

How do perform a file system check that will solve the issue?
This is my boot log:

I also get SpareEvent emails:

Code

A SparesMissing event had been detected on md device /dev/md127.

One more thing, how do I recover data from lost+found, I can't even access the folder.

Thank you

danieliod · 19. Juni 2016

I mean if it can cause any stabilty issues to the system?

danieliod · 18. Juni 2016

Hi,

I have in my Update list the update to Linux-Image-3.2.0-4-amd64 3.2.81-1.
Is it safe to update this?

Hi,

I have followed the steps and in step 2 recieved the below outcome.
Is it ok? Can i start RAID Recovery now?

Thank you very much for the prompt reply.
It seems that one of the drives is out of date and was not captured as part of the RAID.

How to I know the progress?

Hi,

I shutdown my server and connected the SATA cables better, then I saw all my Drives again.
I ran both commands from above and recieved the following:

Code

mdadm: stopped /dev/md127
sudo mdadm --assemble --force --verbose /dev/md127 /dev/sd[bcd]
mdadm: looking for devices for /dev/md127
mdadm: /dev/sdb is busy - skipping
mdadm: /dev/sdc is busy - skipping
mdadm: /dev/sdd is identified as a member of /dev/md127, slot 2.
mdadm: no uptodate device for slot 0 of /dev/md127
mdadm: no uptodate device for slot 1 of /dev/md127
mdadm: added /dev/sdd to /dev/md127 as 2
mdadm: /dev/md127 assembled from 1 drive - not enough to start the array.

I have looked on the System Info and saw that suddently I have also md126 which is inactive

Hi,I have added the new drive and completed the RAID sync.
Should I change now the spare=1 to spare=0 or remove the spare=1 totally?
This is my current configuration:

Code

# definitions of existing MD arrays
ARRAY /dev/md/NAS metadata=1.2 spares=1 name=openmediavault:NAS UUID=332d8084:c2b3a139:44a4f8e1:6865cc49

danieliod · 13. März 2016

Everything works well since the Array finished rebuilding.
Thank you again

danieliod · 7. März 2016

Thank you for the detailed info, it's very appreciated.
I have replaced the SATA cable and the drive boot up correctly.
Then I wiped it via the OMV GUI, restarted and started RAID recovery.
It's running now, let's hope it will last long enough...
I will update once finished.

thank you
