ReadyNAS Ultra 2, OS 6, Dead volume
Hello I have an old ReadyNAS Ultra 2, running OS 6. I was trying to set up MySql on it when the frontend suddenly failed and I had to do a har reboot. When it booted back up the volume was missi...
Your System root volume is at 100%. The services failed to start and getting your volume md127 to stop. I don't think there are issues with the disks (smart_history and diskinfo)
If you are comfortable with SSH you will be able to remove the files or data that consumed the System volume and restart the RAID. Contacting Support is not an option but the Community might be able to help.
If you have full backup of data, Factory reset is another option.
Hope this helps!
Regards
Yeah, I've started a factory reset now.
Thank you so much for havig a look Marc_V , good to know that the discs are probably ok.
I am comfortable with SSH, but I have very little clue as to what I'm doing.
I've been transferring some large database dumps from another machine and I guess, if I understood your answer, it ended up in the root volume filling it up, instead of in the 1TB of free data space... I'm having a hard time understanding the file structure I think, where should I have transferred the files to, assuming default shares?
Did you add MySql via a NetGear app (which should not have put it on the root partition) or via SSH (which would have)? Likewise, what about the apps that are utilizing the databases?
I sent the files from an rpi using rsync, via SSH (I guess...?).
I want to use the NAS as a place to store the state history tables from the database of a Home assistant (HA) instance running on said pi.
I ran the command below on the pi to send the dump file:
rsync -avz database.dump admin@ReadyNAS:/data/home
By creating some test files now, I see that /data/home seems to be the same location as /home. Confusing to a linux novice...
But. /home, which is a link to /data/home on your system (and the default for an XRAID system), is not a share you should be writing to. It's the base share for all the user home shares. It's not directly shareable, and is accessible only using admin credentials. You should create a share expressly for your databases, and it is best if you use something other than admin credentials to access it..
It is in /data, at least, so shouldn't be filling up the OS partition.
Yeah, I realized too late. Being used to windows file structure I thought anything inside /data would be the data share but /data/home apparently is not...
I don't know where the actual databases have ended up, but I'm trusting the MySql app not to put them in the OS share...
I think the problem was that I manually trasnferred a 3GB dump file to the /data/home directory using admin credentials. I guess I at least learned something :P
