Unable to create shares - ReadyNas 2120, Firmware 6.10.8
My ReadyNas 2120 has been in use for several years and has been running fine. It has existing shares.
Recently I tried to add an additional share and it failed. See the error message below. It's grousing about the share name. No name that I enter works.
A reboot of the storage device did not clear the issue. Any idea about what's going on?

I'd guess left-to-right, but I don't have a rack-mount, so I am not sure.
disk_info.log gives you the serial numbers of the disks, so after the backup you could power down, pull the drives, and check for the serial numbers.
Once you have a full backup, it might be simpler to do a factory detault with the new drives in place. You can save the config files first, and re-apply them after the default to speed things up. There are a couple of settings that will miss (but unfortunately I don't recall which ones). If you have installed apps, make sure you re-install them before you restore the config.

The log files indicate that the file system has become Read-Only. I'm not sure how this occurred. Any suggestions regarding how to get around this and restore R/W access?

Download the log zip, and look in there for clues.
Generally it is due to
- a full file system
- disk errors
- btrfs file system errors
Your file system certainly isn't full, so that's ruled out in your case.
If you don't have a backup of the files, I suggest making one asap.
/dev/sdc and /dev/sdd have non-zero uncorrectable sector counts as opposed to /dev/sda and /dev/sdb which have zero uncorrectable sector counts. The volume is a RAID-5 so errors on two disks can be an issue. Considering that this ReadyNAS has >56,000 continuous power on hours, it's not unreasonable to expect drive issues.
I have a second ReadyNAS 2120 with sufficient free storage capacity and am currently running full rsynch backups of the flakey 2120 to it. Upon completion and verification of the backups I will replace the /dev/sdc and /dev/sdd drives, reinitialize the first 2120 and restore the data.
