Jul 12, 20171002030001 - Commit failed when making or checking permissions after firmware 6.7.5 update
My ReadyNAS 214 device has been running very smoothly for months. I use it for backing up and storing a lot of static content on my home network. This morning I noted that I could not copy files from...

It tells me that your OS partition is not full, which rules out one possible cause.
/dev/md0 3.7G 1.1G 2.4G 32% /
This is higher than it normally is (note mine was about 17%) but not anywhere close to full.
I don't have a good next step in mind though. If a Netgear mod requests your logs, it'd be good to provide them for Netgear's analysis.

Thanks - I hope they do reply; my backups are not running right now and that makes me twitchy.

Perhaps your data volume is mounted Read-only.
Look for BTRFS messages inside dmesg.log and systemd-journal.log, and for md127 in mounts.log, and paste the beginning of btrfs.log here.

Thanks for the reply. Inside dmesg.log, there are a large number of the following lines, about 12 per second:
- [Wed Jul 12 07:43:37 2017] BTRFS critical (device md127): unable to find logical 2595263971328 len 4096
Inside systemd-journal.log, there were 2246 instances of:
Jul 11 07:37:08 [redacted] kernel: BTRFS critical (device md127): unable to find logical 2595263873024 len 4096
Inside mounts.log:
/dev/md127 on /data type btrfs (ro,noatime,nodiratime,nodatasum,nospace_cache,clear_cache,subvolid=5,subvol=/)
/dev/md127 on /apps type btrfs (ro,noatime,nodiratime,nodatasum,nospace_cache,clear_cache,subvolid=257,subvol=/.apps)
/dev/md127 on /home type btrfs (ro,noatime,nodiratime,nodatasum,nospace_cache,clear_cache,subvolid=256,subvol=/home)
/dev/md127 on /run/nfs4/home type btrfs (ro,noatime,nodiratime,nodatasum,nospace_cache,clear_cache,subvolid=256,subvol=/home)Looks like read only if "ro" is an indication
The first segment of the btrfs.log:
