Can no longer log in to web interface

akovia · 21. Oktober 2021

I am trying to connect a windows machine to map a drive to my nas, but when I went to log into my OMV5 WebGUI, it just takes my credentials and realods the page.

Thinking I entered the wrong credentials, if I tried anything else I would get an error message stating the wrong user/password.

I haven't updated anything since my last login, so I really don't know what this could be. I also tried from other machines on the network and I get the same result.

I get still access via SSH though.

Please help

Thanks for the link, but neither of the solutions work for me.

I have plenty of space.

Well it wasn't happy about that.

Wasn't sure if I should continue so I'll wait till you say so.

akovia · 21. Oktober 2021

That bad huh?

macom · 21. Oktober 2021

Sorry, no idea. What did you do just before you lost access to the GUI?

akovia · 21. Oktober 2021

Nothing I can think of. I haven't even accessed it in months. I opened my bookmark for it and I just couldn't log in.

Soma · 21. Oktober 2021

Doesn't line 61 say Read only OS?

akovia · 21. Oktober 2021

I'm also confused about all the messages about being a Read-only file system

I wanted to try this fix, but it won't allow me.

Code

cp: cannot create regular file '/var/cache/salt/minion/roots/mtime_map-OLD': Read-only file system

Seems we posted at the same time.

I never set anything as read-only. It's just an odroid-hc4 with an micro sdcard in it. The card was perfectly writable before.

I'm really scratching my head here.

edit: I see the ro statements now, but I have no recollection of ever explicitly setting them that way, or how to fix this.

That usually means problems on the root drive.

Maybe try:

So it appears to be corruption.

This and a reboot seems to have fixed things for now. *crosses fingers*

I live on an island and power goes out a lot. I'm thinking this was the result of an unclean shutdown due to a power outage where the UPS ran out. It's the only thing that makes sense. Hoping this might help the next person.

Since you're running on SD Card, it is a good habit to make weekly copies/backup of the whole card.

Just power down the server, make a full image of the SD (on Windows, I use Win32DiskImager), flash the image to another >= SD and boot the server.
If things go wrong, you always have a fail-safe backup with not much days appart,

As for the UPS ran out: shouldn't it power down the server when it's almost depleated???
Isn't the UPS managed by NUT?
