RN104 - readonly /dev/md127
Hello everyone,
my Ready NAS 104 decided to give me a quest to solve. Since a few weeks may be more I am not abeld to write to my NAS. :neener: First I ignored that I`m not abled to change the access rights on my shares and left changes undone but I want to wirte something new to my NAS and that failed too. :arrow:
The Problem:
- no changes on Shre Access rights possible (Folder operation failed - 1002030000 - commit failed)
- APP indtallation and removal failes
- write to shares is not possible (Access denied)
What I found out:
/dev/md127 on /data type btrfs (ro,noatime,nodiratime,nospace_cache)
/dev/md127 on /home type btrfs (ro,noatime,nodiratime,nospace_cache)
/dev/md127 on /apps type btrfs (ro,noatime,nodiratime,nospace_cache)
/dev/md127 on /run/nfs4/home type btrfs (ro,noatime,nodiratime,nospace_cache)
root@NAS:~# touch /data/test
touch: cannot touch `/data/test': Read-only file system
root@NAS:~#
what I tried: :idea:
differend unmount and remount rw tries
My question is;
Do anyone know how I can get back write acces to the md127?
I had a Ticket with this Inforamtion send to the support but for free they were not abled to help me with this. And as I am just knowing the unix basics I realy need help with this because I don't want to loose data form the RAID.
Maybe someone in here can help me.

- Hello,
There seems to have been a similar case. Please check this link:
viewtopic.php?f=20&t=76989
Unfortunately, this case needed help from support. You could of course copy your data to another destination since you still have read access and have a fresh start with your device.
Running a balance once in a while will prevent the ReadyNAS to unexpectedly run out of space. However, balancing cannot be done when already out of space.
Bye,
Eskender - Hi Eskender,
thaks for your reply. I didn't tried any btrfs commands. Maybe some of that will clearify my issu. But it raelly looks like it's kind of what you worte. My NAS seem to be not smart enough to save enough working space. ^^
root@NAS:~# btrfs filesystem df -h /data
Data, single: total=7.29TiB, used=7.27TiB
System, RAID1: total=32.00MiB, used=864.00KiB
System, single: total=4.00MiB, used=0.00B
Metadata, RAID1: total=2.00GiB, used=571.38MiB
root@NAS:~#
Do you know If it will help or is possible to delet snapshots?
regards,
Manuel - Hi,
Unless you still have snapshots of data that has already been deleted, I think deleting snapshots will only help if you delete the data the snapshot was made of as well.
Just checked the Btrfs wiki. It states 512 MB free on Metadata and 1 GB on Data should be sufficient. It will take a rather long time to complete.
No need for Btrfs commands, you can run balancing by scheduling a maintenance task on the local admin page.
Bye,
Eskender - What's the output of the following?:
# btrfs fi show
# btrfs subvolume list /data - mtakacs, I have split your posts into a new thread to make it easier to follow: http://www.readynas.com/forum/viewtopic.php?f=23&t=81353
