Adding StephenB and Sandshark Hi again, concerning issue with RN212. Had about 4TB stored, all are seemingly gone except a lone iCloud folder under Pictures share. History:1) 3 NAS boxes have been idling for over a month without access2) Last week usin gReadyCloud iOS app, attempted to pull a file - couldn't login3) Selected "reset password", email sent, link followed, password updated, able to access RN212 again4) But instead of all the files I expected, only a lonely iCloud Photos folder (with data)5) Default Shares (Documents, Music, Pictures, Videos) are all visible using Windows Explorer and using Chrome Browser (admin page). All are empty now6) Confirmed firmware is up to date, as is anti-virus scanner7) Also had a scare on other two NAS's but after rebooting them (in addition to RN212) and rebooting my PC, was able to see all files on RN314 and RN528X. However, RN212 remains blank8) Downloaded log files, no idea what to look for Please help!

On the problem itself - though it's too early to say what the chance of getting the data back is, it doesn't sound good. Anything you write to the NAS will lower the odds. So I would either shut it down, or reboot it in read-only mode. It sounds you are saying that the NAS suddenly has a healthy but empty volume (apart from that one picture folder) I am wondering If you had other shares (not the default ones) before that have now disappeared. if the failure might have given you a completely empty volume, with the iClouds photos resynced by ReadyCloud from your phone after the failure occured. On the logs: One option is to contact the mods ( JohnCM_S and Marc_V ) via PM (private message), and ask them to analyze the logs. Send them a link to this thread and a download link (google drive, icloud, dropbox, etc) link to the log zip file. Don't post the log zip here. When I'm looking at them, I always look in disk_info.log at the disk health, and mdstat.log to see what disks are currently in the volume RAID array (md12x RAID groups are the ones in the data volume). I generally also check the bottom of volume.log, as that will tell me the OS partition fullness, and the maintenance bit at the bottom can also be useful. Readynasd.log and status.log will give you a high-level view of what the ReadyNAS application was doing, and that might give you some clues on what else went on around the time you had to reset your ReadyCloud password. You can delve deeper by looking in system.log, kernel.log and perhaps dmesg.log though there is a lot in there.

Are you using the admin credentials for any/all of these? If not, do, in case it's just a permissions issue. I had some folders get the permissions changed without me knowing why, and a few others have reported the same. Resetting them fixed it. Are you comfortable with SSH? That would be the place to absolutely see whether the files are really still there, but have been rendered invisible or inaccessible to you via the other protocols. Could this be from some sync process going horribly wrong? Files were removed from the other location, or the other location became inaccessible, and the sync removed them from the NAS?

Thanks Sandshark and StephenB . Haven't ran SSH in a few months, forgot most of it but will try to bring it up again. Re: admin, I am completely confused on this. Two of the NAS's login using my email address, and one uses "admin". The RN212 (with the problem): when I log in, under "Accounts" it just shows "Admin" and then to the right it shows my email under "Secondary Members". Is there a simple way to "reset all permissions" as you indicated? Sorry for naive questions, I'm really poor at understanding permissions, admin vs. users, etc., especially on this NAS platform.

Thankfully I created an SSH "how-to" document. Logged into the RN212 using admin, interestingly the password was my old password and not the new password I recently updated to. That made me hopeful... Executedcd ..lscd Picturesls And the only folders it lists are the iCloud Photos folder and one more folder I added as a test (unfortunately I did that prior to StephenB 's advice not to do that). Also checked Documents folder, same story. Nothing. Does that conclusively prove the entire machine has been wiped out? If so, I'd sure as heck like to understand how/why... You guys may recall I upgraded this box with 2 Seagate Ironwolf ST12000VNZ008 12TB replacement drives. I did it by swapping in one at a time, so the rebuild process took days but it all worked fine and continued to be fine for at least a month. I'm concerned someone hacked into my home account, or more likely, there's just something wrong with the NAS. But it's weird that the NAS is working fine, and yet all the files seem to be gone. Ugh.

Thanks StephenB for the info below. To answer your first question, there are no new shares, just the defaults.

    Unfortunately, that does appear that your diagnosis is correct -- your files have vanished. You can try to see if ReclaiME can recover any files that you don't have backed up. You can download a free copy and see if it will do the job before you pay for the actual recovery: https://www.reclaime.com/library/nas-recovery.aspx .
