Boot drive full..9.10.2-U2 seems huge

[Penbrock]

I am trying to clear room after getting
CRITICAL: May 27, 2017, 7:55 a.m. - The capacity for the volume 'freenas-boot' is currently at 94%, while the recommended value is below 80%.

I have looked around the forums for help and see one strange thing.

Code:

[root@freenas] /# zfs list -r freenas-boot
NAME  USED  AVAIL  REFER  MOUNTPOINT
freenas-boot  70.7G  1.52G  31K  none
freenas-boot/ROOT  70.6G  1.52G  25K  none
freenas-boot/ROOT/9.10.2-U1  10.8M  1.52G  647M  /
freenas-boot/ROOT/9.10.2-U2  70.6G  1.52G  70.0G  /
freenas-boot/ROOT/Pre-9.10-STABLE-201605021851-893932  1K  1.52G  481M  legacy
freenas-boot/grub  25.3M  1.52G  6.34M  legacy

Why is 9.10.2-U2 so HUGE next to 9.10.2-U1?

 

[Ericloewe]

70GB? Yeah, something is on the boot device that should definitely not be there.

 

[zoomzoom]

Simple enough fix, save the config, then clean install. See @Ericloewe's post below

 

[Ericloewe]

The config could be the source of the problem, though. FTP stuff ending up on the boot device is surprisingly common.

 

[zoomzoom]

@Ericloewe I didn't realize that... is there a way to mitigate that prior to it occurring?

 

[Penbrock]

So s fresh install is best? Or backing out to U1 then deleting U2 and install the latest?

None of that. Figure out what exactly is taking up so much space, fix that and go on your merry way.

We can probably help once you've identified the storage hog.

The question is too vague to be answered. As I said above, this needs to be examined before action is taken.

I am used to Ubuntu a little and thought /boot/ only held the OS.
Where do I go to dig down to see what is taking the space? This server is set up to feed a large move and TV shows collection using the Plex plugin.

I do have 3 volumes each made up of 2 mirrored 3t drives.

Where do I start digging to find the issue?

It's supposed to, but if you put something else there it can fill up. What's the output of du -sh /*?

I was going to respond to you that I did not have FTP services running when I thought I would make sure before just saying it and low and behold FTP IS turned on! I do not use it so turning it off will not effect me at all (in fact it is a bit scary to have it opened. I did firewall SSH but never thought FTP was even on)
Where is the FTP logs,files, ect saved by default so I can delete them and turn it off?

 

[danb35]

Turning it off is easy; just turn off the switch in the web GUI. Logs are stored in /var/log, which is on your .system dataset, which isn't a problem if you have sensible system settings (i.e., your .system dataset is not on your boot device). Any files received via FTP will be in wherever the FTP path is--go to Services in the web GUI and click on the wrench next to FTP to see what that's set to.

This is what is shows

Code:

[root@freenas] ~# du -sh /*
4.0K  /COPYRIGHT
 69G  /TV
723K  /bin
 55M  /boot
5.0K  /compat

[danb35]

There's your problem; you've put the TV folder on your boot device. It should go on your pool. But this is strange, because your output isn't showing anything for /mnt, which is where your pool would be. What's the output of zfs list?

[danb35]

OK, looks like it was doing the same thing mine is doing: taking a long time to calculate the usage for /mnt, so you only showed the output through /media. Your answer is simple: move /TV (or its contents) somewhere else--looks like /mnt/movies/PlexTV would be the place. mv /TV/* /mnt/movies/PlexTV.

And then figure out why you were putting things in /TV, and change that process to put them in /mnt/movies/PlexTV.

Edit: I see you have a separate pool called TV, and another called RAID2. I'm not sure what your intent is in this regard, but I think you can probably adjust the above command appropriately. But seeing that you have a pool called TV makes it easier to understand what happened--you meant to put stuff in /mnt/TV, but put it in /TV instead.

 

[Penbrock]

Not sure how but thanks, I do see that one of my series was placed in that /TV folder. deleting the files now as they are also in the normal pools

 

[Penbrock]

Down to 1% used. Thanks again all
