ReadyNAS NV+ (sparc) - OS Partition 100% - How to Fix

[gmhitchcock]

I've been unable to access NAS via Frontview. Can view shares and access via ssh. How do I clean up the OS?

I'd start by running commands such as these:

# cat /var/log/frontview/raidiator_version
# du -csh /var/*
# du -csh /var/log/*
# du -csh /var/log/frontview/*

You are looking for e.g. a large log file or something like that that is filling the OS partition.

See below:.... looks like /var/log/

What next? Remove the upnp-av.log? Any others?

[mdgm-ntgr]

upnp-av.log is the log for ReadyDLNA.

Rather than removing it, I would do

# echo "" > /var/log/upnp-av.log

/var/log/syslog and /var/log/daemon.log are also quite large. You may wish to copy those to the data volume (in case they contain something important) then empty them.

You may also wish to do e.g.

# tail -n 100 /var/log/syslog

to see if there are any important messages in the log.

What about

# du -csh /var/log/frontview/*

Could be some large log files in there.

[mdgm-ntgr]

Also, once you are finished fixing this you may wish to update to 4.1.14-T6 which addresses ShellShock: http://www.readynas.com/forum/viewtopic.php?f=17&t=59222

Preformed each of the above.

Still can't get Frontview access.... still get "contact support error message".

[mdgm-ntgr]

Can you try the commands mentioned here: http://www.readynas.com/forum/viewtopic.php?p=384618#p384618

You probably need to try restarting Frontview.

[gmhitchcock]

See below: Same error message from Frontview.

You get the same error message when you attempt to open Frontview?

Have you tried rebooting your NAS?

Have you tried clearing your web browser cache (e.g. Temporary Internet Files in IE), closing your web browser, then reopening Frontview?

[gmhitchcock]

1. Yes
2. No
3. cleared, no change.

Rebooted NAS, now can access Frontview. However, RAIDar 4.3.8 shows -- under the information icon and setup is greyed out.

Regarding 4.1.14-T6, I downloaded it, but it had no extension? Is this correct?

So maybe some files were corrupted when the OS partition was full.

Yes, that's correct.

Install it via System > Update > Local in Frontview. If the checksum is not valid, the NAS will refuse to install it.

[gmhitchcock]

System updated. We have a winner.... Thanks for your help.

[mdgm-ntgr]

You're welcome.

An OS re-install would also have helped, however considering the important security update in 4.1.14 beta, I figured updating to that would be better.
