Recover "Broken" Raid 6

Hi All

I need some assistance from our Raid Gurus...

I needed more space, so i expanded my rail with mdadm and add one more 2TB drive to my 10x 2TB Raid 6. Raid was in "clean" state.
About an hour later i noticed that the raid has gone to "degraded" and that two drives show up as "removed". After doing some checks, i found that one was a drive failure and the other one was the new drive i just added. I replaced the faulty drive and added the two drives back with as follow:
mdadm --manage /dev/md0 --add /dev/sda1 and mdadm --manage /dev/md0 --add /dev/sdb1
i did a check - mdadm --query --detail /dev/md0, and it showed up as all 11 drives synchronizing and i left them - took two days - to complete the Sync.

This morning i mounted the drive, but i am unable to see any data???
I also checked command df and it shows that my drive is empty... Did i just lose all my info or is there ways to check if the "index" file is not correct or if i can re-buid the index file ?

Any assistance will help at this stage.

Shut Down ClearOS from RPI with NUT server - Possible?

Hi all

I would like to know if it is possible to send a "Shutdown" command from a RPI to my ClearOS.
I run domoticz on the RPI and i can monitor the UPS load and battery status to shutdown at a predetermined value.
I would prefer to NOT connect the UPS to ClearOS as i have a few things connected to it.

Hi All

Thank you for all the effort that was put into resolving this issue.
I was able to leave my server off until today, not everyone can do this, and waited for a solution - i just ran the update from the web interface the moment i booted.
After the update ran, i also did:

systemctl stop clearsync.service
rm -f /var/lib/csplugin-events/events.db
systemctl start clearsync.service

Everything is now responding and i do not see any more log files going "NUTS"

Thank you again for everyone involved

Hi All

My unit started to show similar issues yesterday morning 09:00 SAST.
As the day progressed it became more and more unresponsive to the point where i could not access the system anymore at about 22:15 SAST

The only thing i saw was that there was a update that started at 02:10 SAST and that u had a high number of events, when i was still able to access the WEB interface.
I have now powered my system off - pulled the plug - as that was the only way to shut it down as i lost WEB and SSH access last night.

I hope that someone can assist before i attempt to do a clean install - not really looking forward to it...

Hi Nick

I tried "systemd-analyze set-log-level notice" last night, did a reboot and it made no difference.
I am now not able to access my unit at all

Did a "HARD" reset so that i can get in and copy from /var/log/messages

It seems that my system is getting overwhelmed, so bad that i can't login even via ssh anymore.

What i did see before i could not get in anymore was a higher memory usage by clamd

Any idea where i can look to find out what is causing this?

Hi Nick

My setup is a bit different, i shall see if i can setup something similar and do a test.

Hi Nick

Yes, in Gateway mode, my LAN speed was always good, between 80 and 115kBps, it has been the WAN side that was slow i could only get about 40Mbps download on the WAN side.
Both ports tested in LAN mode now give me about 920Mbps, so i am not sure how to move forward.

At the moment i have a small DELL R210 setup as a Gateway and my Media Server is on the LAN side of that.
With the DELL R210, i am getting about 97Mbps on a 100Mbps connection.
The difference is that the DELL R210 is a Gateway only, on my media server i have PLEX, Samba and Transmission
