RN314 read only file system
I've been using a RN314 for backup purposes for a bunch of years now and all of a sudden the filesystem is read only. As this is a backup system and the primary storage is still intact as well as the...
I had no idea there was sensitive information in the log files. I unshared the file.
I only recreated the data volume. I might have factory reset the nas a long time ago though. Probably years ago.
I've replaced a few drives over the years.
Your NAS is having trouble communicating with one or more of the drives. Are you seeing ATA errors recorded on any of them? Note that the drive often will record an ATA error even if the problem is with the NAS, so don't jump to the conclusion a drive is bad. That takes some more testing.
Step one would be to (with power off) pull and re-seat all drives, checking the integrity and cleanliness of the connectors as you do so. If the log doesn't point to a specific drive, doing the built-in drive test might.
No ATA errrors since the last reboot. Smart test passed on all the drives. I'll ask someone on site to reseat the drives. If that doesn't work I guess it might be time to replace the NAS alltogether. It's done it's job flawlessly since 2013.
I got someone on site to shut the nas down. Pull out all the drives, clean out all the dust and reinsert the drives. Unfortunately it only took a few minutes after powering on until the volume was back to read only. Waiting for a quote for a replacement NAS, but until then I'll try a factory reset as a last resort.

What you did wouldn't solve the btrfs errors that are already on the data volume.
A factory reset will. Though I still recommend getting a UPS for the NAS (this one or the replacement).
I factory reset the device and let it recreate and resync the volume before I created any shares. So far, so good. Last night the backup wrote about 500GB to the volume and no error messages yet. I still ordered a replacement NAS to be on the safe side. It's not really practical to connect it to a UPS where it's located right now. The NAS needs to be as far away from the primary storage as possible and there's just not enough room for a UPS.
Since everything is mirrored to cloud storage every night and power to the building is very reliable I'm not really that worried.
Thanks for your support.
