Good day everyone! I've got a problem creating containers. I installed the system, evrth went quite well, I created containers and destroyed and dumped and restored. Evrth was fine. But suddenly I tried to create a container and it said

Creating container private area (debian-8.0-x86_64)
/usr/lib/vzctl/vzctl/scripts/vps-create: 53: test: Illegal number: 2.62483e+090
vps-create ERROR: Failed to get available disk space on /var/lib/vz/private/1000.tmp

There is 2.5 Tb of free space. this error is shown when I use simfs layout, if I use ploop, then it says
....
Error in ploop_mount_fs (ploop.c:1326): Can't mount file system dev=/dev/ploop31453p1 target=/var/lib/vz/private/1001.tmp/root.hdd/root.hdd.mnt data='(null)': Invalid argument

take look at failed script:

52 AVAIL=$(awk "BEGIN {print $(stat -f -c '%a*%s/1024' $VE_PRVT)}")
53 test "${AVAIL}0" -gt 0 ||
54 vzerror "Failed to get available disk space on $VE_PRVT" ${VZ_FS_NEW_VE_PRVT}

Obviopusly test on line 53 was unable to handle 2.5Tb converted to kilobytes.

You can modify this line, to work around the problem,
but I afraid you can fail on other place.

I believe it's better for you to create small partition for containers private areas.

thanks for answer! I'll try to do smth with the script. But I'm just confused about the fact that I have already created containers here on that 2,5Tb disk earlier. I think that I upgraded the system after those successful attempts and that upgrade changed smth, but I can't exactly say what was upgraded, I just made "apt-get upgrade"..

The problem was triggered by output of
awk "BEGIN {print $(stat -f -c '%a*%s/1024' /some/partition>)}"

Please check who is guilty here: awk or stat ?

my df -h shows

/dev/md0 2.7T 108G 2.5T 5% /
there is no special partition for /vz catalog, so I should replace <some/partition> to /dev/md0 ? right?

then I have the following

# awk "BEGIN {print $(stat -f -c '%a*%s/1024' /dev/md0)}"

originally it was $VE_PRVT -- i.e. directory for containers private areas.

You can use "/" here, stat should return the same numbers for any directories of the same partition.

but /dev/md0 -- is wrong, it is located on another (tmpfs?) partition

Directory for containers private areas is /var/lib/vz/private/

so I try:

awk "BEGIN {print $(stat -f -c '%a*%s/1024' /var/lib/vz/private/)}"

and this is the result

2.62468e+09

so how I understand this is the result which the script can't handle?

the command

stat -f -c '%a*%s/1024' /var/lib/vz/private/

results in 656168065*4096/1024

Yohooooooooo!!!!

I just commented out the tests in that script /usr/lib/vzctl/vzctl/scripts/vps-create - on line 53 and on line 86 and it works!!!!
Thank you SU much, vaverin!!! It's a shame of me, that didn't think carefully about the error line
"/usr/lib/vzctl/vzctl/scripts/vps-create: 53: test: Illegal number: 2.62467e+090" - it gives the whole info.

But I still have what to do))) repaired creating the 'simfs' containers only, not 'ploop'. Now I'll go and take a close look on ploop.c)))
