The paths for the shares listed below could not be found
My ReadyNAS NV+ v2 is reporting the following message and all of my shares have disappeared:
"The paths for the shares listed below could not be found. Typically, this occurs when the ReadyNAS is unable to access the data volume.
media
backup"
None of my data is visible anymore.
The Full Story:
Disk 2 started to report a huge amount of Command Timeout errors and eventually failed.
I bought a replacement (same model) and hot swapped it.
Before the sync had completed (as far as I can tell) I got "Detected increasing ATA errors on disk 2" and "Detected increasing uncorrectable errors". The disk was a duff!
I left it for 6 days but it still hadn't reported that the sync had complete (wasn't showing as running on the LED screen of the NAS either)
3 folders in the "media" share still had their files, but another 2 (around 1TB of data) were showing as empty (in both Finder/Explorer and in the ReadyNAS web interface thing) but the capacity was still reported as it had been before the failure, which made me think that the data from those 2 empty folders was still there somewhere but inaccessible because the sync messed up because of the dodgy replacement disk.
Also noticed that my Time Machine backups had stopped running because the "disk isn't available"
I bought a second replacement drive and swapped it and got the following:
"Data volume will be rebuilt with disk 2"
Again, no word on whether sync had completed or was even running and so after 9 days I rebooted the NAS though the web interface.
It then reported "Volume scan failed to run properly" followed by "The paths for the shares listed below..." error listed above.
I also received the following e-mails:

media
backup
I found some logs and with my limited knowledge I figure one or more of the below could shed some light on the issue:
kernel: EXT4-fs error (device dm-0): ext4_find_entry: reading directory #18940539 offset 0
kernel: Buffer I/O error on device md2, logical block 0
kernel: EXT4-fs error (device dm-0): __ext4_get_inode_loc: unable to read inode block - inode=3119620, block=49807808
Things like that
Can anyone shed any light on this? Is some kind of partition issue/table/sync issue where the data is actually still there just not readable in its current state? Does anyone have any suggestions of how to fix this or, failing that, getting the files off onto another external drive so it I can factory reset and then plop the data back on?
I do have "backups" of the data, but the thought of spending countless hours re-ripping hundreds of CDs and DVDs in preparation for a relocation abroad is making me feel sick. I'm sure even a very long-winded recovery process would be quicker than that.
Any advice/help appreciated!

Ah I see. Still, I'm glad I'm aware of this. Knowledge is power

You might want to check and see if the NAS hardware is O.K. or not. If it came up so easily in a Linux PC one would suspect there may be a hardware issue with the NAS unit. Perhaps run a few passes of the memory test boot menu option for instance. There may be some other hardware problem.
I was very surprised to see it just appear in Linux so easily like that, with all of the folder and file structure intact and all data readable too after weeks of being unable to see anything through the web interface or ATP, SMB/CIFS, windows etc and with all those nasty looking log entries. It does seem to have been working ok the last few days since doing a factory reset and putting all the data back on from fresh after it all re-initialised. I'll get the memory test running now and will do a few more passes throughout the day. It has served me well over the last few years but part of me kind of wants there to be a hardware problem so I have more of an excuse to upgrade to a NAS with enough processor power to transcode with Plex but I'll see what the tests indicate first...
