Hello
i try to set a vps diskspace to 100 GB

i ran the following command

vzctl set 110--diskspace 100000000:100100000 --save

then when i ran df on the vps it says


Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/simfs            41718452   3221336  33665168   9% /

Hello,

And what's the problem? Smile

You've described the situation, but there is no information in post about what confuses you?

the problem is that when i set the diskspace to more than 40 GB it only shows 40 even if i set it to 80 GB
and when the /vz partition gets filled i find that disksapce from df -h inside the vz automatically decrease from 40 to 38 to 35 to 30 GB and so on

------
forgot to say
i got this from /etc/fstab

/dev/sda9 /vz ext3 defaults,usrquota 1 2

i have quotas on but when i try to start up a vps it cannot and alwayse say quota error file exists wven when i delete /var/vzquotas/* or do anything
so my only fix to make it able to starta vps is to runthe following command

quotaoff /vz
then when i start my vps's with disk quotas on they start but the problem i described above occures

There is an article at wiki, where this behaviour is described:

Please, start the VE in question (let VE id is <veid>) and provide the following information:

1) output of `df -a`
2) output of `vzquota stat <veid>`
3) output of `cat /etc/vz/conf/<veid>.conf`
4) output of `cat /etc/vz/vz.conf`

Thanks.

P.S. Please, attach this information as a separate files!

hello
thanks for your interest in helping me i do appreciate this
here is the data you asked

commands are excuted and output attached as per requested

ps. this problem is not specific to a certain VEID but its global to all vps ( i cannot make their df to show a total disk space above 40 GB and when /vz has less than 40 GB free i find that total disk space from the vps df command shows the free space of the /vz partition and my problem is that i want to be able to make df for any vps shows the amount i put in the VEID.conf regardless of how much free space i got on the HN /vz partition )

Hello!

According to

# vzquota stat 111
   resource          usage       softlimit      hardlimit    grace
  1k-blocks        2716712        39000000       39100000
                                    ^^^^^

you set a blocks limit for 111th VE to ~39Gb, and only ~2.7Gb are used in VE. Remember these numbers.

According to

#df -a
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda9             95121228  62907700  27381580  70% /vz
                       ^^^^       ^^^^^^

/vz partion is of ~95Gb size and ~63 Gb is used, so ~32Gb is free. Remember these numbers to.

Ok. When you give a df command inside VE, what should it output in this situation? First, consider the total amount of space. Should df output 39Gb? No! VE can't write so much, because there is not enough space on /vz partion.
According to http://wiki.openvz.org/OpenVZ_disk_quota%2C_df_and_stat_weir d_behaviour
df should output quota_usage + free_ext2 = 2.7 + 32 = ~34Gb. This is what we see in your output:

# df -a
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/simfs            34930264   2716712  27381604  10% /
                        ^^^^^^

So you problem is actually formulated in http://wiki.openvz.org/OpenVZ_disk_quota%2C_df_and_stat_weir d_behaviour:
"Do not set random disk quota barrier/limit! Even if you want VE to be unlimited, consider reasonable values."

HTH,
Vasily.

If so, why do you want to set so big blocks limit? Smile

Why not decrease it?

Thanks,
Vasily.

Lolz
thats because i wanted to oversell diskspace and then add new HDDS and the real partition gets filled physically
so am i able to set diskspace string in the VEID.conf to a number higher than the sum of ( the free space on the /vz partition + used space by the ve itself )

More, you can oversell diskspace.
BUT. There is one problem. Some applications like RPM use df output
for determining whether they will succeed. So df should not report
more space then there is *really* physically available on the disk.

So if you have only 1Gb free on /vz, and set 100Gb limit on all your VEs - ok, but df will still show MAX 1GB free.

If you still want to show more - do a small patch for kernel, but I informed about potential problems.

take a look at fs/simfs.c, function quota_get_stat()

I suppose you are interested in 2 if's:

if (buf->f_bfree < free_blk)
adj_blk = free_blk - buf->f_bfree;

if (free_blk < buf->f_bavail)
buf->f_bavail = (long)free_blk; /* min(f_bavail, free_blk) */
