Hi, I have 4 HDDs in my OMV5 system. The system disk is /dev/sda, and three data disks /dev/sdb, sdc, sdd.
Randomly, after a reboot, the previous /dev/sda system disk will be /dev/sdd and, of course /dev/sdd becomes /dev/sda.
There are no abnormalities in the operation of the system other than this. Everything is working properly.
Only I get stupid when for example, I issue the hdparm -C /dev/sdd command.
Can anyone tell me how to fix disk names so that they never change?
Since 5.5.20 drives are mounted by UUID and not label any more:
https://www.openmediavault.org/?p=2866
Not sure if it is possible to manually edit the mntent sections in /etc/openmediavault/config.xml and deploy the changes (which would rewrite fstab).
I'm sad about that. Thanks for the reply!
Hi,
I want only dev-disk-by-label mount points in the /srv directory. OMV has mounted some HDDs by UUID.
Unfortunately, OMV notes that no label was specified at mount time.
The HDD will be labeled later, but after that OMV is always mounted it by UUID.
How to delete this information from OMV (reset to default) or manually re-mount these HDDs by label?
It does not seem like a good idea to manually write this in the fstab file. Unmount - mount did not help.
I tried to find it with atop, but didn’t succeed with it, so I reinstalled OMV today.
One good way to figure out what is wrong is to reinstall from scratch. And then verify that the disks spin down.
Sorry for the late answer.
I wanted to avoid reinstallation. But I see I can't avoid it. Thanks.
It is possible that you have configured the S.M.A.R.T monitoring in OMV to check the drives every 10 minutes. Take a look to verify that it isn't so.
No, the S.M.A.R.T. time is set to 7300 seconds to do not obstruct HDDs spin down (7200 seconds). But, the rotation of the discs does not stop.
No, I have OMV only. But if you recommend something, I'll install it.
Something reads all data HDDs (sdb, sdc, sdd) every 10 minutes.
Therefore, the disks are not able to stop, they are constantly spinning.
Can anyone help me figure out which process reads HDDs regularly?
Please note I have played a lot with hd-idle and you should not use the original version, it's garbage and stops working after some time if you put your server in standby.
I installed it with a simple command: apt install hd-idle
Would this version be a garbage that should not be used?
It works perfectly for me so far. I am forced to use it since I installed OMV5, because the spin-down hasn’t worked.
To set individual spin-down times for HDDs, first reset times to 0 and then can set different times.
Example: hd-idle -i 0 -a sda -i 1800 -a sdb -i 3600
I hope it works.
Levi I'll let you know if I can get it working and how I did it.
I looked at the link you wrote, it doesn't seem difficult.
All right, look forward to the result. Thanks for trying to help.
Not trying to be harsh but I haven't worked on the plugin in over two years...
No, you were not rude at all to me, just honest. I just wanted to know whether it is worth the wait. I'm sorry for my writing is equivocal.
My friend (Google) who helps me with translation, doesn't know my mother tongue well. So, sometimes my thoughts are not exactly described.

Clear speech. That's all I wanted to know. Thanks.
Me too. I misunderstood your answer. 
But I hope the developers respond at least.
Is there any hope that any developer will check and fix the plugin?
Please, answer at least sincerely.
An answer came in the meantime.
I have a similar problem with the Plex plugin and the same error message.
Something may have happened to the plugin recently.
Plex may have changed something.
It might help: the /etc/default/plexmediaserver environment file is not created.
Edit - 4.0.3 is in the repo now
The plugin can be reinstalled. Thanks.
I have tested this modification and the plugin could be installed in this case.
But I think you need to fix the plugin in a new version.
I just wanted to help you.
Symptom:
- clean omv install
- install plugin openvpn first time
- plugin creats /etc/openvpn folder
- enable plugin
- creates /openvpn/pki subfolder to store settings
- uninstall plugin
- remove /etc/openvpn (by user or other program)
- reinstall plugin openvpn
- plugin does not create /etc/openvpn folder
- does not notify user - no message
- enable plugin
- error thrown when you click apply "mkdir: cannot create directory ‘/etc/openvpn/pki"
- tries to create the pki subfolder, but it is unable to (openvpn folder is missing)
Solution I think:
- to create /etc/openvpn folder by user -> I did this and Openvpn works fine again. But this is not a real solution.
- to delete info that shows for plugin this is not the first installation.
So plugin creates the folder again if it is missing.
You can easily replace this if after uninstalled plugin delete /etc/openvpn folder.
