Disk full after misconfiguring transmission [SOLVED]

[daydaydream]

It seem there is a problem with transmission after and the reboot and it wrote some of the download to the router disk. I am not very good with command with telent, I think the problem files is in the overlay:

df -h
Filesystem                Size      Used Available Use% Mounted on
/dev/root                 5.0M      5.0M         0 100% /rom
tmpfs                   243.4M      4.6M    238.8M   2% /tmp
/dev/ubi0_7             143.9M    143.9M         0 100% /overlay
overlayfs:/overlay      143.9M    143.9M         0 100% /
tmpfs                   512.0K         0    512.0K   0% /dev
/dev/sda2                 7.3T      2.3T      5.0T  31% /mnt/sda2

tried to use winscp but there is no space left

If you can't remove your misplaced stuff selectively from /overlay/upper/ via ssh/ rm (which might be possible, as jffs2 doesn' like ENOSPACE) followed by a reboot, you might have to resort to a factory reset.

Hi, is the filesystem messed up? it seems / and /overlay/upper has the same files, is it safe to rm files in upper

Save config backup, reset.
jffs2 becomes read-only once it has one flash block remaining.

Thanks. It works after the reset, the diskspace is back to normal now.
