ReadyNAS 104 /data (dev/md125) mounted readonly after reaching 499GB full of 927GB
Hi,
After a long time of very happy service this weekend my NAS turned to readonly .. rather unusable since we mount our linux homedir from it.
After some invetigation we discovered that the btrfs filesystem was mounted readonly. with no way to get it to becom rw again.
ive tried to scrub data (no errors reported), balance (no errors reported) but to no avail.
The configuration is a raid1 of 2 1 GB devices.
The subvolume list seems rather long .. but I have no idea of how to fix this.
Please help me so we can get back to work again.
kind regards
Dieder Timmers
