Problem partition full

[Philou15]

Hye

Sorry i'm french so my english is not good.

I have a jeedom on proxmox 5.2 and the last 2 night i have proxmox bug.

I would like to acces on log but on ssh when i put on console
/var/log/daemon.log

proxmox say permission denied but i have log my console on root with ssh

And i Have a probleme
My systeme have a ssd 32gb and i think the ssd is full

on ssh i put lvs he say :

root@jeedomok:~# lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
data pve twi-aotz-- 13.06g 100.00 0.61
root pve -wi-ao---- 7.25g
swap pve -wi-ao---- 3.62g
vm-100-disk-1 pve Vwi-aotz-- 20.00g data 65.31


And on the web interface the local-lvm is full,


That solution i have ? because my VM ID 100 is not full on disk.

Tks
Sorry for my english

I would like to acces on log but on ssh when i put on console
/var/log/daemon.log

proxmox say permission denied but i have log my console on root with ssh

`/var/log/daemon.log` is a logfile - not a command - try `less /var/log/daemon.log`.

Your thinpool is 13.56GB large - vm-100-disk-1 is 20GB (too large)

You need to delete something inside vm-100 and run `fstrim` afterwards

 

[Philou15]

Yes i have 20Gb on vm100 disk but i use only 40% of 20Gb,
It is not full so that solution for down vm100 disk to 10Gb ?

Tks

 

[Stoiko Ivanov]

you need to run fstrim - inside vm 100

 

[Philou15]

Ok tks but how

I log on sddh

i put fstrim and he say :


root@jeedomok:~# fstrim
fstrim: no mountpoint specified

Tks

 

[Philou15]

I have delete log and save on my VM 100 ( On jeedom directily ) but the local-vm already 100%

So it is not my vm. I use 5Gb Of 20 Gb on disk Vm100.

I waiting the command fstrim for test because i dont say the good i tking.

tks you very mush

 

[Stoiko Ivanov]

read the man pages - `man fstrim` - you need to specify a mount-point - for example `fstrim /`

 

[Philou15]

My english is very bad, so i dont understand..

I dont find the commande i put on ssh
root@jeedomok:~# fstrim /


and no reaction


root@jeedomok:~# fstrim /
root@jeedomok:~#

tks

 

[Stoiko Ivanov]

in the VM (jeedomok):
try 'fstrim -v /' (then you get an output)
run `fstrim -v $fs` for every filesystem in the output of `df -h`

then on the PVE-host check the output of:
`vgs`
`lvs -a`

hope that works

 

[Philou15]

OK i would like to reside the disk of my VM 100 but not down the size it is up only, so i have 20GO and nox 42Go.....
I have put the commande and no way.

that is the screeen shoot
Tks for your help

 

[Stoiko Ivanov]

Run fstrim inside the VM 100, not on the hypervisor.
Connect to VM 100 (via GUI -> VM -> Console), log in, run fstrim

 

[Philou15]

Tks you

It ok now, the partition is not full now.

What explication ?

And now i would like to reduce my partition of VM because I have create a 42GB and i use 5go,
The GUI propose to augment but not reduice partiton

42gb to 10 Gb that solution ?

Tks a lot

 

[Stoiko Ivanov]

Hm - in the first post the lvm-volume was 20G, now it's 42G ?

In any case you only have 13.06 g on the thin-pool.

Reducing the Partition is more difficult than augmenting.

I guess the best option is to search in google for "Reduce KVM LVM" (in french) - I'm sure there are many helpful links !

Hope this helps!
