RND2000 Duo v1 - lockup after boot - OS partition full?

(NB: reposting since it appears my original post never got published for some reason...? https://community.netgear.com/t5/Using-your-ReadyNAS/RND2000-Duo-v1-lockup-after-boot-OS-partition-full/td-p...

Thanks mdgm.

 

So my plan is good? (presuming it is a full root...)

 

Can you advise on copying the large logs to the data partition? (I'm not a Linux user, although I'm working on it!)

 

# cp /sysroot/var/log/frontview/error.log   /???/backup_frontview_error.log

First check that the OS partition is full

# cd //

# df . -h

# df . -i

 

The first df will tell you the space usage on the OS partition.  Normally it would be no more than 25%

 

The second df will tell you the inode usage on the OS partition.  Inodes are used for metadata, and if you run out you won't be able to create new files on the OS partition even if there is free space.

 

Assuming you are running out of space: 

You'd put the oversize logs on the C volume.  The best thing to do is park them in a share.

 

So first create a subfolder in a share

#mkdir /c/sharename/log_files

Then 

# cp /var/log/frontview/error.log /c/sharename/log_files/backup_frontview_error.log

    Thanks StephenB.

     

    I'll give it a go over the weekend and report back!

    If you are in tech support mode, you will need to mount the C volume.

     

    I believe the following will do that (hopefully mdgm-ntgr will correct this if it is in correct).

      No, not that. Something like:

       

      # mount --bind /proc /sysroot/proc
# mount --bind /dev /sysroot/dev
# mount --bind /dev/pts /sysroot/dev/pts
# chroot /sysroot /bin/bash
# vgscan
# vgchange -a y
# mount /dev/c/c /c

        Thank you for the assistance mdgm and StephenB.

         

        I've now had the opportunity to investigate further and successfully boot the NAS into tech support mode and connect via PuTTY; df outputs below.

         

         

        root@:/# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hdc1             1.9G  359M  1.5G  19% /
sysfs                 1.9G  359M  1.5G  19% /sys
tmpfs                 1.9G  359M  1.5G  19% /ramfs
tmpfs                 1.9G  359M  1.5G  19% /USB
/dev/c/c              1.8T  178G  1.6T  10% /c
/dev/c/c              1.8T  178G  1.6T  10% /c

root@:/#  df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/hdc1             128000    8079  119921    7% /
sysfs                 128000    8079  119921    7% /sys
tmpfs                 128000    8079  119921    7% /ramfs
tmpfs                 128000    8079  119921    7% /USB
/dev/c/c             60981248   37340 60943908    1% /c
/dev/c/c             60981248   37340 60943908    1% /c

        Presuming I'm reading that correctly, disc space is not my issue, with 93% inodes and 81% space free.

         

        Next step?
