ReadyNas524X - Lost admin Home Folder !!!

Hi,

 

Running ReadyNas 524X 6.10.10

Although I can login as admin, it appears that the admin home folder is not accessible anymore.

Is there anything I can do to try attempt recovery?

Like chkdsk, msadm etc??

 

Appreciate any guidance.

Thanks and kind regards,

I've not (and won't) update to 6.10.10.  But I'm wondering if anyone else has noticed this.  It could be an unwanted by-product of eliminating ReadyCloud.

 

But it makes me wonder why you care.  Using the admin credentials as your normal login is generally a bad idea, so you'd have little use for the admin home folder.

If you navigate into home, are you seeing admin there?

Hi,

 

Thanks for the replies.

 

If I ssh in then I get the following from /home

 

admin@Donkey:/home$ ls -lisa
ls: cannot access 'admin': Input/output error

total 16

...

263 0 drwxr-xr-x 1 AUser users 712 Feb 23 2023 AUser
? ? d????????? ? ? ? ? ? admin

 

If I use the webgui and look at the shares I get a list of users of which admin is 1 of them.

If I then click on admin I get a progress bar that does not end and a rotating cog icon that continues for ever.

 

If this was NTFS I would say that the MBR File Descriptor has gone, but should be recoverable using various OS and 3rd party tools.

As this is a Debian derivative Linux I think that there is an inode problem.

 

Firstly is the RAID 5 constructed using mdadm in which case I would try some msadm tools etc.

If not any idea how the raid is constructed.

 

Thanks and kind regards,

Normally it is recommended to log in as root when using ssh.  But I do see my admin folder when I log as admin on a system running 6.10.10.  Note this is an RN102, not an x86 NAS.

 

FWIW, the file system is btrfs, so no inodes. The home folder is actually on the data volume (you are accessing it via a mount point).  You could try running btrfs check --force /dev/md127 (logging in as root) and see if that finds anything.  If you try this, be careful not to access the data volume while the check is running.  Otherwise you might crash.

Your permissions for AUser are not what I expect.  Normal, they should be rwx------.  Having you been making permissions changes with SSH?  I don't specifically know how that could cause this error, but it's not a good idea.  And if it wasn't you who made the change, I wonder if it's related.

MHi,

 

Once again thanks for the replies.

I will change share permissions.

I have ordered a new 2TB drive, compatible with the existing as I noted msadm -D /dev/md0 was reporting /dev/sdc as removed. Having checked that the drives are physically fitted correctly I am assuming that sdc is not behaving itself 😉

Additionally the RAID is marked as Read Only.

If the change of HDD resolves the problem I will report back

 

Many thanks,

Generally that means the NAS is seeing BTRFS errors that it thinks are putting your data at risk.  If you have no backup, then you should definitely make one before doing anything else.
