Re: Shares disappeared after restarting Frontview manually.

fooboo · ‎2016-05-20

ReadyNAS NV (I know, I know) running latest firmware.

Been a faithful user for years.

Somewhere between restarting frontview and nfs-kernel-server via command line (in an attempt to tighten up nfs share security), it looks like my shares disappeared from Frontview (they are still there under /c)

/etc/frontview/apache/Shares.conf is empty

/etc/frontview/samba/Shares.conf is empty

Strangely, if you look at the screenshots below, the shares now show up as user accounts so something went sideways as well as the exports (over CIFS, NFS, AFP) no longer being accessible.

If I go to a different machine and do a "showmount -e <nas>", I am able to see the NFS exports but am not able to mount (probably due to missing perms)

I am still able to ssh in and have backed up /etc onto a different machine via rsync. I have not tried creating a new share yet as I'm not sure if that might make things worse.

I'm really hoping that I can recover without having to blow everything away.

I did check the output for "df -h" and "df -i" and I'm fine on disk utilization as well as # of inodes consumed.

What's the output of the following?:

# df -h

# df -i

nas01:~# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/hdc1 1.9G 343M 1.6G 18% /

tmpfs 16k 0 16k 0% /USB

/dev/c/c 182812672 619305 182193367 1% /c

As mentioned, I don't think space is the issue (even though /c is getting a little full)

Here is the output of ls.

As you can see the Shares.conf are showing as zero. I'm wondering if adding a new share will help populate those files sufficiently that I can manually add the other old shares back in. Obviously, I want to avoid deleting those shares...

Digging around, I see that others have complained about possibly the same issue but appears to be no resolution...

I am not seeing your shares in your ls output, just your user account folders.

If the shares are there, have you backed them up?

kohdee · ‎2016-05-20

You might be able to try restoring the original config files from /etc/default/config/etc/frontview

cp -rP /etc/default/config/etc/frontview/* /etc/frontview/

fooboo · ‎2016-05-20

Please see the link above for similar problems experienced by others. It looks like the shares and users somehow get confused and dumped into /etc/passwd.

The initial ls screenshot shows /c which are just the shares. I have blanked out the user account names (blue stuff). The shares are still there as of now and no, the shares are not backed up right now and therefore I'm hesitant to try to, a) delete the shares showing up as account names and b) try to create a new share to try to manually determine the format necessary to recreate the existing shares.

I've got another NAS coming (hopefully by Monday) so my plan is to back up to that first via rsync.

fooboo · ‎2016-05-20

Oh cool!

I found a (semi?) intact Shares.conf at

/etc/default/config/etc/default/samba/Shares.conf (it's missing /c/u001 and /c/vmdatastore)

[backup]

comment = "Backup Share"

path = "/c/backup"

public = 1

writeable = 1

oplocks = 1

[media]

comment = "Media Server Share"

path = "/c/media"

public = 1

writeable = 1

oplocks = 1

Similarly, /etc/default/config/etc/netatalk/AppleVolumes.default

After restoring the files and cleaning out /etc/passwd, what do you recommend as the best way to restart things? Reboot or restart services? (AFP, CIFS and NFS are all currently impacted for me).

No, that's actually the default config file; that's the config it would have used if you factory defaulted. You can copy the default config Shares.conf to the /etc/frontview/samba/Shares.conf to match your existing shares and get yourself back up and running. You might also be able to check /var/backups/ to see if there is a config backup there of your original shares.

fooboo · ‎2016-05-20

Ok thanks. I looked in /var/backups and it appears that there are a number of compressed tars there so I'll copy them off and look around.

Is it safer/better to either cherry pick the files that I need or just copy it over completely?
I'm assuming that I should reboot after copying the files over? Or should I just restart frontview from the command line?

Thanks much! I'm excited about the prospect of getting things back to normal.
