Hello,

I got strange problem. I cannot live migrate one vps to another server.I cannot even vzdump it on the existing server.

Rsync copies data much above user quota.User has 36GB and Rsync goes to 46GB and does not stop!

I tried to do strace of this proccess and here is info
it continues all the time probably at the point when it fullfill all disk space
select(1, [0], [], NULL, {60, 0})       = 1 (in [0], left {60, 0})
read(0, "\374\17\0\7", 4)               = 4
select(1, [0], [], NULL, {60, 0})       = 1 (in [0], left {60, 0})
read(0, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4092) = 4092
select(1, [0], [], NULL, {60, 0})       = 1 (in [0], left {60, 0})
read(0, "\374\17\0\7", 4)               = 4
select(1, [0], [], NULL, {60, 0})       = 1 (in [0], left {60, 0})
read(0, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4092) = 4092
select(1, [0], [], NULL, {60, 0})       = 1 (in [0], left {60, 0})
read(0, "\374\17\0\7", 4)               = 4
select(1, [0], [], NULL, {60, 0})       = 1 (in [0], left {60, 0})

Ok I let the vzdump working...it has ended after:

INFO: vps is online again after 218 seconds
INFO: creating archive '/backup/vzdump-4820.dat' (/var/tmp/vzdumptmp9173/4820)

You have new mail in /var/spool/mail/root


70GB size?? How it is possible when:
[root@L57 ~]# vzlist -a
      CTID      NPROC STATUS  IP_ADDR         HOSTNAME
      4820        112 running 10.10.10.10.   spvps
[root@L57 ~]# vzctl exec 4820 df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/simfs             39G   33G  5.3G  87% /
tmpfs                 4.0G     0  4.0G   0% /lib/init/rw
tmpfs                 4.0G     0  4.0G   0% /dev/shm
[root@L57 ~]#


Quota is 39GB for this VPS. Can you tell me the reasons for this? Thank you in advance.

Well, I found the reason. Maybe this would help someone.

Somhow, I don't know why, client went over quota on old server.

df -h showed 33GB but in fact he did 70GB

On the new server the proper quota was set and rsync could not move this vps. I think vzmigrate should report that but it didn't.
