After update RN102 from 6.2.5 to 6.4.0 it sends mail with root usage 86%

After update RN102 from 6.2.5 to 6.4.0 it sends mail with root usage 86%

I've updated my ReadyNAS and now i get mail notifications that the root usage is 86%.

I think it isn't true beause the data storage has over 700GB free space and /dev/md0 has 2.4GB free space.

What's wrong? Where can I find the reason for that message?

 

ssh cmd: df - h /var

Filesystem      Size  Used Avail Use% Mounted on
tmpfs            10M  4.0K   10M   1% /dev
/dev/md0        4.0G  1.4G  2.4G  36% /
tmpfs           249M   44K  249M   1% /dev/shm

It looks like 36% root usage to me.  But check inodes for md0 also (df  -i)

You are right. The inode usage is 86%.

 

Here the original message from df -i:

Filesystem     Inodes IUsed IFree IUse% Mounted on
/dev/md0        65536 56246  9290   86% /

 

How can I fix it?

There must be some folder that has a bunch of small files (maybe even 0 length).  Basically you need to search for it.  /tmp, /var/log, /var/cache are good places to start.

 

With OS 4.2, that is usually the ReadyDLNA artwork cache.  But with OS 6 that should be in /apps - which is on the C drive.

 

Once you find where the files are, it might be clear that they can safely deleted.  If not, post back here.

 

Best to update your backup first - it is easy to make a fatal mistake with ssh.

 

 

Netgear can fix it remotely also - so you could try support.netgear.com.  Even if you are past the 90 window, they might help w/o charge.

I found many files in /var/backups. Recently I have made a backup of the configuration. I think this folder can be cleared?

I have also some mysql databases in /var/lib/mysql. I will transfer them to the hard disk drives.

 

Only these two folders are filled with many small files.

 

I try it and give a feedback here.

 

Thanks for your advices.

I don't know how /var/backups is used - so I'm not sure if it is safe to clear or not.

 

Generally there is 1 inode per file.  My RN202 has is using about 11000 inodes on the OS partition.  So you are looking for about 40,000 files - not a handful.

There is no effect by doing anything.

I (re)moved nearly 2000 files and the output of df -i is the same.

I guess the filesystem is corrupt but I don't know how to fix the root filesystem.

 

I tried shutdown -rF (Parameter F doesn't exist) and touch /forcefsck an reboot system. No effect.

The last checked property of  "tune2fs -l /dev/md0" shows "Sat Oct 18 21:19:31 2014". 😞

How can I force a fsck scan at the root partition?
