(Solved) - Syncing Issue (Possible duplicate of 678 681 - but my setup is different so didt think i should write it there) #683

After reading syncoid fails in Ubuntu 20.04.2 LTS kernel 5.11.0-25 due to zfs receive -s issue #665 Which explains that a wrong version of ZFS userspace (zfsutils-linux) and ZFS kernel module (in my case build into the kernel) is the reason for this. And Ubuntu 20.04.2 LTS kernel 5.11.0-25 zfs send | receive broken I tried to install Ubuntu 21.10 Beta in a VM.
And ZFS userspace and kernel module I know the versions dont match exactly. But the Syncoid send/recieve worked without a hitch. So suppose i have to wait for Ubuntu 21.10 on some machines. Hope this will help others out there figuring this out. Best regards, |

I've expected this problem would eventually happen with Ubuntu having HWE kernels with zfs integrated, but the userspace tools of the original distro release. So... today with a 20.04.3 focal LTS HWE kernel 5.11 and the zfs 0.8.3 userspace, I set out to surgically upgrade the userspace tools.

Hi Garrett.
Another option may be to run the Jonathonf PPA which contains the latest
OpenZFS bits -- currently at 2.1.1.
https://launchpad.net/~jonathonf/+archive/ubuntu/zfs
I have lots of machines running that build and it is working well.

First, I added |APT::Default-Release "focal";| to
"/etc/apt/apt.conf.d/01-vendor-ubuntu"
Then, since 5.11 is the hirsute kernel, I added the following to
"/etc/apt/sources.list" (adjust for newer HWE kernels):
|deb http://us.archive.ubuntu.com/ubuntu/ hirsute main restricted deb
http://us.archive.ubuntu.com/ubuntu/ hirsute-updates main restricted
deb http://security.ubuntu.com/ubuntu hirsute-security main restricted |
Then I created the file "/etc/apt/preferences.d/zfs.pref" and put the
following in it:
|Package: zfsutils-linux Pin: release n=focal Pin-Priority: -10
Package: libnvpair3linux Pin: release n=focal Pin-Priority: -10
Package: libuutil3linux Pin: release n=focal Pin-Priority: -10

Finally, I did a |apt update && apt upgrade libc6 libc6:i386
zfsutils-linux|
In the end I got:
|# zfs version zfs-2.0.2-1ubuntu5.3 zfs-kmod-2.0.2-1ubuntu5.1 |

Every time im trying to receive a Dataset. At the end of the transfer i get.
If i use the same command again there is allways data missing that it resyncs.
Followed by another error
This is my setup
Im receiving from Ubuntu 21.04 on RPI4 (ARM64)
Kernel version:
Linux rpi4-ubuntudesktop 5.11.0-1019-raspi #20-Ubuntu SMP PREEMPT Tue Sep 21 15:23:42 UTC 2021 aarch64 aarch64 aarch64 GNU/LinuxAnd receiving on Ubuntu 20.04 on RPI4 (x86_64)
Kernel Version:
Linux zboxri531-lubuntults 5.11.0-37-generic #41~20.04.2-Ubuntu SMP Fri Sep 24 09:06:38 UTC 2021 x86_64 x86_64 x86_64 GNU/LinuxOn both version im using the built in ZFS in kernel.
No dkms module in use here.
I followed the install guide for ubuntu and this is my syncoid version
I have done as described in Syncoid wiki on the end sending for non root user.
sudo zfs allow -u <MyUser> send,snapshot,hold <MyPool>I have used
sudo suon the receiving end so all commands are Super User.My command with debug is as following.
Doing the command again sometimes finishes it.
But then end with a new error.
cannot destroy snapshots: permission deniedCommand with debug as follow
I hope its possible to be resolved.
Ty for reading,
Darkyere
