pve-zsync with bind mounts fails

[Jero]

Hi guys,

I can't use pve-zsync on lxc containers with a "mp" reference in the VMID.conf file. Like my previous requests i don't care about the state of the mount point because that is a different ZFS pool just used as bulk storage.

Is it a bug or do i need to make a feature request?

Greets,
Error

Like this one.. https://bugzilla.proxmox.com/show_bug.cgi?id=1007

 

[wolfgang]

No this is not related to pve-zsync.
pve-zsync is a standalone packet.

I read that "Recursive sync" is a feature not so easy to realize. On the other hand, about this bug/feature... How complicated is it?
Do you have an ETA to fix it, depending on other proxmox development priorities?

Thank you!

 

[wolfgang]

Hi,

no there is no ETA and I can't tell you when it will be done.

Sorry for the noise, but for me it seems that it works as designed!

Despite the bug report and information that is not being implemented, I've done a paranoia try:

This works, but then I was looking for an possible explanation in the code

Line 763 in /usr/sbin/pve-zsync , function sub parse_disks is treating the mp(mount point) use case.
next if $line !~ m/^(?(?:virtio|ide|scsi|sata|mp)\d+)|rootfs): /;

Sorry, but I was talking about "Recursive sync" and not mp.
