simfs crippled?

RoboCotRoboCot Member

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).

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

  • eastoncheastonch Member

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

  • RoboCotRoboCot Member

    Ticket sent. I'll keep you informed :)

    BTW i'm on Illinois datacenter.

  • eastoncheastonch Member

    @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.

    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?

  • RoboCotRoboCot Member

    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

  • rds100rds100 Member

    That's 2.6.18.

  • yomeroyomero Member

    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?

  • nabonabo Member

    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.

  • RoboCotRoboCot Member

    @netomx said: can you tell me what is wrong there?

    31Gb - 723 Mb = 5,2 Gb.

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

  • netomxnetomx Moderator, Veteran

    @RoboCot said: illinois math

    lol, didnt get that :(

  • RoboCotRoboCot Member

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

  • camargcamarg Member

    lol mine too

    root@test:~# df -h

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

  • vedranvedran Veteran

    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!

  • camargcamarg Member

    @yomero said: Same node???

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

  • yomeroyomero Member

    @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).

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

  • RoboCotRoboCot Member

    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)

  • rds100rds100 Member

    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.

  • nabonabo Member

    @RoboCot said: 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)

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

  • RoboCotRoboCot Member

    @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.

  • rds100rds100 Member

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

  • rds100rds100 Member

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

  • RoboCotRoboCot Member

    @rds100 said: @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% /
