Re: RN316 does no finish booting and OS install gives error "could not extracting files) last F
@StephenB , Hey, I do not have a backup of the data.
I would rather not reboot and get a SMB backup started.
I tried to start a backup from the PC but the RN316 would not accept my credentials when attempting to validate the source or could that just be the lack of SMB installed?
Re: RN316 does no finish booting and OS install gives error "could not extracting files) last F
To start smb from the chroot involves a few commands including starting smbd using the path of the binary.
Though it would probably be best to free up some space on the 4GB root volume first. You're using a lot of space on the 4GB root volume. There should be some log files that have grown large or some files that shouldn't be on the root volume or something else going on.
That's a lot of metadata for the 4GB root volume. Mine has 10.89MiB used out of 204.56MiB.
Metadata is data about data. Every file has metadata associated with it. A high amount of metadata could suggest that you may have a huge number of files on the 4GB root volume e.g. from an app storing data there that should be on the data volume.
Re: RN316 does no finish booting and OS install gives error "could not extracting files) last F
Metadata is not a folder, it's a part of the file system, somewhat akin to a files allocation table. A scrub is the way it's normally trimmed, but you've run out of space for that.
I think there is an old version of Plex installed but it hasn't be run since long ago.
Plex is an app that creates a lot of small files, I think. If it wasn't configured correctly and stored a lot of these on the 4GB root volume that could explain the large amount of metdata.
You'd have to look around the 4GB root volume to confirm whether it's there or not. The basics of how to do that have been posted a number of times on the community.

Where did you read that? A btrfs scrub reads all data and metadata blocks and verifies checksums.
Oops, I meant balance. I'm not sure if the balance itself does it, or the process of doing so kickstarts the automatic expansion process, but I have definately seen more metadata as a result after I partially vertically expanded a volume and no metadata was added at that time.

As I am quite busy at work and not versed in Linux, a kind sharing of the syntax and CML needed would be quite useful to me, rather then to tell me to go search on a certain web space which is also full of all kinds of stuff.
Re: RN316 does no finish booting and OS install gives error "could not extracting files) last F
Hi all, could anyone, please, share the syntax for the commands to get into the folder that is full and delete the ok-to-delete files so that I can do OS reinstall? Thank you.

First you need to find out what is full.
Enter these commands in ssh (logging in as root), and post the results
mount --bind / /mnt
cd /mnt
du -csh *
On my RN524, I am getting this:
0 apps
6.4M bin
0 boot
0 data
24K dev
11M etc
30M frontview
0 ftp_ban.tbl
0 home
4.0K homes
33M lib
4.0K lib64
0 media
0 mnt
4.6M opt
0 proc
36K root
0 run
11M sbin
0 srv
0 sys
0 tmp
290M usr
682M var
1.1G total
Comparing my results with yours will help us find out where the extra space is going.
