FreeNAS boot drive almost full, help! -- Solved

[hikurakx]

Got a alert for the freenas-boot volume is at 96%,

Ran "du -sh /*"

Code:

4.0k    /COPYRIGHT
726k    /bin
48M    /boot
1.5k    /cfg
9.3M    /conf
17M    /data
31k    /dev
4.5k    /entropy
5.5M    /etc
512B    /home
  5M    /lib
85k    /libexec
8.2T    /media
1.5k    /media2
4.8T    /mnt

3.8M    /sbin
512B    /sys
512B    /tmp
456M    /usr
537M    /var

then check the snapshot for the boot drive:

Then check the "System Dataset", it's not on the boot drive:

Then check the space for the boot drive:

No idea where the space go.. :( please help, thank you!!

Updates to the OS create an automatic backup of the previous version in case you need to roll back because of intended issues. Pending updates (I think) download for when they are ready to be installed. If your OS is stable since the last update - or two - then you can safely delete the previous versions. This can all be found in the System Update tab http://doc.freenas.org/9.10/freenas_system.html#update

Edit: on second glance, it appears there are no backups from an upgrade. Sorry, I'm unable to help further.

Try this. It looks at hidden files and skips /mnt and /media.

Code:

#!/bin/bash
for i in $(/bin/ls /)
do
    if [ "$i" != "media" ] && [ "$i" != "mnt" ]
    then
        du -sh /$i
    fi
done

Thank you, I will try this and get back to you!

I figured out how to turn it into a one-liner:

Code:

du -sh -I mnt -I media /* /.*

That's what I figured, but I wanted to make sure.
I'm curious, what do you have in /media? Pools typically mount into /mnt.

Yes, media is another NFS mount from the Synology:

Code:

mount -t nfs 192.168.x.x:/volume1/share  /media

 

[Sakuru]

Ah, ok. Do you have any folders in /mnt that are not part of your pool?

 

[hikurakx]

I just checked and doesn't look like there are any other folders or files beside the pool.

 

[Sakuru]

How about /media? I'm grasping at straws here, this is bizarre.

 

[diedrichg]

Save your config to an external computer or drive. Pull the FreeNAS USB. Wipe it in another computer. Verify the full free space. Reinstall FreeNAS per your desired method and import your saved config.

I wish I can do that. Its in production and I can't just do that. :(

Code:

du -sh /.zfs/snapshot/*

 

[hikurakx]

Code:

du -sh /.zfs/snapshot/*

 

[hikurakx]

I ran

Code:

zfs list -t snapshot

teespool is the pool, so those snapshots should be inside the pool right?

 

[Sakuru]

Correct.

zpool get all freenas-boot

and

Code:

zfs get all freenas-boot/ROOT/default
