Hello Steffan.
Thanks for the log!
[2020-09-23 03:00:03] [ 25] Info2 | Unable to adjust LVM2 snapshot size (LVM2 free space is too low) - ignoring
[2020-09-23 03:00:03] [ 25] Info2 | Simfs layout detected - using "live_sync" backup mode
Long story short:
1) openvz-diff-backups was running as expected
2) downtime is caused by the lack of LVM2 snapshots
3) you need to use some OVZDB options to overcome this issue
# --------
If you can (but it can be tricky, even dangerous), try to free some space on LVM2 volume in order to have al least 1 Go of free space.
After that, OVZDB will be able to use LVM2 snapshots and there will be no more downtime.
# --------
If this is not possible, please use "-o 8" and "-o 16" optimizations (8 + 16 = 24):
=> 8 : pre-sync container data before doing a backup (should decrease suspend time when LVM2/ploop snapshots are not available)
=> 16 : detect and use nocache command (on source and master hosts) to preserve legit kernel page cache when creating a backup
Using "-o 8", OVZDB will sync data twice :
- the first copy will not suspend the CT (there might be some rsync errors, this is harmless) and inodes/dentries will be loaded in kernel cache (you have enough RAM on the Host)
- the second copy will suspend the CT (in order to get a consistent copy of data) but suspend time should be highly decreased because 99% of files will be already synced
Using "-o 16", OVZDB will use "nocache" command :
# wget https://ftp.nluug.nl/pub/os/Linux/distr/pclinuxos/pclinuxos/apt/pclinuxos/64bit/RPMS.x86_64/nocache-1.1-1pclos2019.x86_64.rpm
# yum install nocache-1.1-1pclos2019.x86_64
So, on this (old) OpenVZ 6 host, you should use this command ("-t" option tells OVZDB to run at full speed):
# openvz-diff-backups backup <CTID> auto -k 7 -o 24 -t
Later, tell us if it solve your problem!

Mmmmh... What layout are you using on this server? Simfs ?
Could you send me the OVZDB backup log file?
I would like to understand and, if possible, correct the issue.

Tonight i did a first backup.
But the containers getting blocked, no ping, no access, nothing after more then 10 minutes i stopped the backup.
SO fort his openvz6 server i will keep my old backup system. The server is planned for reinstalling with openvz 7

You have inserted the code at line 138.
please delete it and insert it line 213:

Sorry still not working,
but the quota format error is comming from this vps, it uses 2nd level disk quota and is 32bits
so this VPS will need to migrate the content to a new one.

Hello Steffan.
Could you try this ?
*** 1) install latest release
# OVZDB_RELEASE="v1.0.1.12-stable"
# cd /usr/local/sbin/
# wget <https://download.openvz-diff-backups.fr/releases/openvz-diff-backups_$%7bOVZDB_RELEASE%7d.tar.gz> "https://download.openvz-diff-backups.fr/releases/openvz-diff-backups_${OVZDB_RELEASE}.tar.gz"
# tar xvzf openvz-diff-backups_${OVZDB_RELEASE}.tar.gz
# mv openvz-diff-backups_${OVZDB_RELEASE} openvz-diff-backups_stable
# ln -s openvz-diff-backups_stable/openvz-diff-backups openvz-diff-backups
# rm openvz-diff-backups_${OVZDB_RELEASE}.tar.gz
*** 2) add Bash-static
# cd /usr/local/sbin/openvz-diff-backups_stable/
# sed -i "s/\#\!\/bin\/bash /\#\!\/bin\/bash-static /" openvz-diff-backups lib/*
# vi lib/ovzdb.inc
Line 213, just above "# FIXME (low): hardcoded (CMD_NOCACHE - never called directly)", insert:
readonly CMD_BASH="bash-static"
export CMD_BASH
*** 3) check
# openvz-diff-backups update all auto
=> *Notice* - your release is up to date. Yay!
Normally, backup task should work. :-)

Hello Steffan.
Unfortunately, I cannot provide a patch: it would require too much modifications.
But, after checking with a CentOs 6 container having the same bash version (4.1.2), you can use "bash-static" from Debian packages.
https://packages.debian.org/jessie/bash-static
The only file needed is "bash-static".
On CentOS, save your "/bin/bash" and put "bash-static" at the same place.
openvz-diff-backups should now works.
Have a good day!

You mean making a backup on the openvz6 and then import it on openvz7?
I didnt see that in the documentations but i can give it a try
But i find it a strange problem and i dont think the vfsv1 is the problem
If i look at the mountpoints the other containers also have jqfmt=vfsv1

Hello, Steffan
Can you try openvz-diff-backups and provide your feedback, using the updated instructions sent here on the mailing list?

Trying to make a node empty so i can restore it with openvz7
But this server has a old container of a client
ovztransfer.sh failes with the message:
Running quotacheck ...
quotacheck: Unknown quota format: vfsv1
Supported formats are:
vfsold - original quota format
vfsv0 - new quota format
rpc - use RPC calls
xfs - XFS quota format
is there a way i can fix this so this container can run under openvz7?
Thanx
