simfs crippled?

RoboCot

It's me or there is something wrong?

df -H File system Dim. Usati Disp. Uso% Montato su /dev/simfs 31G 723M 5,2G 13% / tmpfs 269M 0 269M 0% /lib/init/rw tmpfs 269M 0 269M 0% /dev/shm

Is there a way to use fsck with simfs?

Thanks!

No free space on the node (i.e. oversold node HDD space).

RoboCot

Good to know. Ticket to bluevm on the way...

eastonch

ouch, that doesnt seem right lol! Let us know the outcome @RoboCot

RoboCot

Ticket sent. I'll keep you informed :)

BTW i'm on Illinois datacenter.

eastonch

@robocot do you know much more about your spec of your server? Just curious, it's not relating to your problem, but i'm curious what plan you're on with BlueVM.

nabo

BTW @RoboCot, can you do a dd if=/dev/simfs/ | dd of=/backup/bck.iso as root to generate an ISO-copy of your HD or do you get access errors?

RoboCot

BlueVM answered. They said it's caused by abusers overusing space on the node and that a technician will fix it. Does this mean that disk quotas are not enforced? I dunno.

@eastonch i have a bluevm3

BLUE3 (Illinois) 256 MB of Guaranteed Ram 512 MB of Burstable RAM 2 CPU's (@2.5 Ghz+ Each) 1 IP Address 40 GB of Storage 1 TB of Bandwidth

@nabo i can't do it because i don't have /backup mounted. What's it?

There is a bug in some .32 kernels with vzquota's. I

I had a VM that VZQuota thought was only using 30GB, it was actually using 520GB.

@daniel it could be:

uname -a Linux ikulkran 2.6.32-308.el5.028stab099.3 #1 SMP Wed Mar 7 15:56:00 MSK 2012 x86_64 GNU/Linux

rds100

That's 2.6.18.

yomero

Indeed.

So, "users overusing space". You can't do that ¬_¬ In other words, the users are not allowed to use their assigned space?

Translation: overselling not only RAM, but even disk space.

can you tell me what is wrong there?

I'm just interested if it is possible for you (no access restriction) to make a iso-copy from the whole filesystem for backup-purposes. The dd of= can be changed to any file you like as it is the iso generated from the filesystem.

31Gb - 723 Mb = 5,2 Gb.

I'm not an expert in illinois math, but i suspect it's not 100% correct ;)

lol, didnt get that :(

RoboCot

I said illinois because my vps is there. Not intended as a pun toward you.

lol mine too

Same node??? If is a different one... holy CRAP

vedran

It's not that bad to oversell disk space, but in that case you should monitor it and under no circumstances run out of disk space!

camarg

@yomero said: Same node???

don't know where can I find the node name in hypervm?

yomero

@camarg said: where can I find the node name in hypervm?

Dunno, (I can't remember) but probably if you have the same IP than @Robocot to access to the vz console (don't post it xD).

JoeMerit

lol! i'm going to start using all my 40GB and we'll see if I get terminated for abuse!

RoboCot

i tried to dd some big files and i'm able to create them exceding the free space (0% left, but i can create more files)

rds100

There is 5% fs space reserved and hidden for root by default.

Not sure you can save an image of a filesystem on the same filesystem.

Were you able to use the /dev/simfs/ as the input file?

RoboCot

@rds100 said: There is 5% fs space reserved and hidden for root by default.

5% of 40gb is 2gb. I create 3 files of 4.3gb each.

rds100

@nabo there is no /dev/simfs, this is not how OpenVZ works.

rds100

@RoboCot that's 5% of the entire /vz filesystem on the node, not specific to your VPS.

This explain the results of my tests.

df update: /dev/simfs 43G 3,3G 17G 17% /
