RAID Volume Full - INPUT/OUTPUT Errors on File Commands Via SSH (ReadyNAS NV+ 1GB RAM)
Last night I SSH'd into my NV+ and wanted to clean up the boot volume, as it was 89% full and I had been experiencing issues with the unit booting up completely. I reviewed /var/logs to look for larg...
What do you see when you enter
# ls -al /dev/mapper/c-c
Hi Stephen,
Here is the result of ls -al /dev/mapper/c-c
Linux nas 2.6.17.14ReadyNAS #1 Wed Jun 20 20:08:20 PDT 2012 padre unknown
nas:~# ls -al /dev/mapper/c-c
brw-rw---- 1 root disk 254, 0 Jan 16 02:16 /dev/mapper/c-c
nas:~#
Also, here is the result of doing a cd into /c/media directory:
nas:/c/home# cd /c/media
-bash: cd: /c/media: Input/output error
nas:/c/home#
Same error happens on all directories and files.
Thanks,

Well, you shouldn't have done this:
nas:/var/log# cp upnp-av.log /dev/c/c
since /dev/c/c isn't a mounted file system and neither is /dev/mapper/c-c (which is what /dev/c/c links to).
I don't know exactly what that cp command did, since the link (and /dev/mapper/c-c) both appear ok in ls. So I don't know how to recover from the mis-step.
You could try rebooting the NAS (and maybe doing an OS reinstall) - it's possible that will resolve it.
Do you have a backup of your data? The direct solution is to do a factory reset, rebuild the NAS and restore data from the backup.
Yup I totally realize I should not have done that cp command - it was late and I have put the mouse down and gone to bed. I want to try and save the data on the X-RAID volume, as I have very old backups and would prefer a fix over factory reset. I think I will open a support case with Netgear before I restart the unit, since I have SSH access working with no issues.
Anyway, thanks for the tips and if I get it resolved I'll post an update.
