Re: Readynas services greyed out of unavailable

With this sort it is the end that is interesting, not the head.

wvkregten · ‎2016-09-29

This was the whole list imho :). and that 738 and 7748 were the end.

Which part or on which folder do i need to do the command in order to see the root volume?

My guess is /dev/md

wvkregten · ‎2016-09-29

I now found out that if I install the update named Glib6 (Glibc6_2.13.38deb7u8.0-1.bin) and after that Sickrage that Sickrage can install and will run.

I also tried manually installing sickrage see command line:

NetgearNAS:/Data/NAS# chmod a+x Sick
Sick-Beard-development.zip SickRage_15.09.05-i386-1.bin

Any ideas?

StephenB · ‎2016-09-29

the first one started from /dev/.udev, which is not a useful place to look.

You can't start from /dev/md0, as that is not a folder.

Start with cd //, and look in one folder at a time (cd into the folder, run the command and note any large files). You are looking for big stuff - 10 megabytes and larger, not the tiny stuff you listed.

The most Interesting folders are generally

/frontview

/usr

/var

/etc

/tmp

/lost+found

Then maybe

/bin

/sbin

/lib

/lib64

/root

It seems a lot of services are missing from /etc/default/services

Add-ons you have installed such as Plex should have entries in there.

Your root volume is fairly full which may have interfered with the upgrade a bit. The first step is to find what's filling that up.

Yes if you need the glibc add-on you do have to install it again after every firmware update as the firmware includes an older version of that.

That's not how to install add-ons. It's not an executable.

Better now? What would be your advice beside factory reset @mdgm-ntgr

mdgm-ntgr · ‎2016-09-30

Start by looking for what's filling the 4GB root volume.

wvkregten · ‎2016-09-30

I did by advice of Stephen here in the above comments. Please read that?

Any other way i can find what is filling the 4 GB? Pls help me in somewhat more detail. I am no Linux (Debian) expert.

mdgm-ntgr · ‎2016-09-30

You can try using the du command e.g.

# du -csh /var/log/*

I think you missed var in your earlier posts. /var/log is actually the most likely place.

mdgm's command gives you the total space used in the folder, mine gives the space used by the biggest files. Slightly different ways of getting to the same thing.

wvkregten · ‎2016-09-30

Tonido and libicudata.so aren't usual, so you must have done something to add them (sickrage???). Tonido does takes quite a bit of space (perhaps 100 MB), but I don't think you've found the real problem yet. You need to seach /var (and /var/logs in particular).

I don't see them in the spam quarantine.

Try again, using different wording. Maybe also send a PM in case it gets lost again.

wvkregten · ‎2016-10-01

for **bleep**s sake they keep disappearing.

How do i send a pm?

So I managed to get another NAS with 10 TB. I am now copying my data.

Will a factory reset help me? What is the difference in OS reinstall and factory reset? Factory reset wipe the root partition also or something?

I am willing to factory reset if my data and settings is safe. But just wondering.

I also wonder why my logfiles (even in code) do not get posted and seem to disappear even after them 10 times...

No idea.

Factory reset does a new factory install (reformatting the disks, and starting clean). It will resolve the services being greyed out. You'll need to reconfigure the settings and restore the data from backup.

Is factory reset my only or best option? @mdgm-ntgr @StephenB

No other conclusions from all the logs?

The greyed-out services and other symptoms suggest something has gotten corrupted on the OS partition.

Netgear support could possibly find/fix it, but the best way for you to ensure that everything is back to where it should be is to do the reset (though I realize it is time-consuming and annoying).
