Whats best way to check diskspace each vm is using in qubes

[raah...@gmail.com]

is there a better way then using df command in each vm terminal? Would be nice to be able to eyeball the size of all vm's in a list. dom0 gives me the total size but i can't figure out how to see what each vm is specifically using in total.

Also i was wondering if my firefox/html5 issue might be because of small space in /tmp. When watching a long video in firefox the video will constantly stop and i have to refresh the page a couple times and skip to where it left off. quite annoying and i've had to resort to downloading the videos to watch them.

Thanks

Rich.

Check `qvm-ls -d`. There is "priv-curr" and "priv-max" column. It will
not be exactly used space in /rw filesystem, but pretty good
approximation.

This may be the case, same as in chrome[1]. You can make more space
there by remounting tmp:
sudo mount /tmp -o remount,size=512M

I am having a problem updating a Fedora-based templateVM. The VM starts (green icon) then fails. The log says it has run out of memory.  qvm-ls -d gives me:
Priv-max=20480MB Root-curr = 7769 MB Root-max = 10240MB State-on-disk = 9510 MB Priv-curr 608 MB

Qubes 3 is installed on a USB3 device.

Is there any way I can increase memory allocation? I have already increased the private storage capacity but that didn't seem to help.

tks man! just what i was looking for! i notice a disk column too? THough none of them see to add up to what df shows me from dom0, for the /dev/mapper/qubes_dom0-root

And yes increasing /tmp fixed the issue ty once again!! I was wondering, i actually made it 1024M is that too big, could that be a security risk? you're the best Marek!!

[raah...@gmail.com]

ah ok so apparently i have to issue that command everytime i start the vm if i need it.

You could also turn on View/Size in the VM Manager. That will show
root+private size for each vm.

tks for tip that would help to monitor for changes. But I also was curious what added up to the 21gb used when doing df command in dom0.

[raah...@gmail.com]

so when I add everythign up in disk columng after doing qvm-ls -d it adds up to about 16.5gb so I guess i should just assume that dom0 is about 5gb.

You could do that. You could also make it permanent in the template by
adding the following to /etc/fstab (adjust size as needed):

tmpfs /tmp tmpfs nodev,nosuid,size=1G 0 0


...and you could also put the original remount command in
/rw/config/rc.local (and make rc.local +x) to make it permanent only
for that app-vm.
