Zitat von Gst

I have to leave now (looking for the kids), but if there is anything more I can do at the weekend i`d be lucky to hear about.

Leave it until the weekend, the fact that it won't stop makes no sense, it's something I have not come across.

geaves · 17. Januar 2020

My guess is it's related to Plex, how is it installed?

Gst · 18. Januar 2020

I tried it once again, without Putty, direct an after a reboot.

for mdadm --stop /dev/md127

i receeved:

mdadm: Canno get exclusive access to /dev/md127: Perhaps a running process, mounted filesystem or active volume group?

gui shows (as all services had been stopped before) following:

what else can I do?

what else can I do?

Look in Diagnostics -> Processes

Something is accessing that raid array that is preventing it from being stopped.

geaves · 18. Januar 2020

Found a 3 year thread on here post the output of lsof /dev/md127

Gst · 18. Januar 2020

thank you for looking
The link I had posted shows Diagnostik > Processes (doesn`t is?)

you missed the / before dev that's why it failed look at what I typed

No, your image is the gui of the running services, tells us nothing

Gst · 18. Januar 2020

sorry for the missetake

it seems as it happen nothing...

root@OMVneu:~# lsof /dev/md127

That would suggest there are no open files on the array which makes no sense.

Let's see if it will force a stop mdadm --stop --force /dev/md127 if that errors again then look at the output of this

ps aux the list will be long but you are looking for something that is accessing the raid or a reference to Plex

That makes no sense

Lets try another way round mdadm --stop /dev/md127 -- force

could for this be the problem that Putty is running ?

Putty should be on the remote machine, how are you running these commands are you using ssh via putt from another machine or are you typing directly on omv via it's own command line?

Gst · 18. Januar 2020

to copy the results to post it to you I again changed to putty (on my windows pc).
I can also put the commands in on the omv line, if nessessary. I´ve just to switch the keyboard.

Do everything via putty from your windows pc leave omv alone that's the idea of using putty.

geaves · 18. Januar 2020

This still doesn't help as to why the array will not stop.

Well that's a start, and it tells us that a drive has been removed, which must be /dev/sdd

So back to the GUI, leave Putty alone, Raid Management click recover on the menu bar, does a dialog come up? and does it display /dev/sdd?

Jetzt mitmachen!
