Hi, we officially do not support this OS yet, but I'll look at it, thank you for raising this issue

Hi, thanks for your comment . But where can I find the list of supported versions of linux kernel and operating systems?

[Swistusmen]

Hi, so: -we are currently supporting kernel till 5.15 mainline, Centos and RHEL have another versioning so their 5.14 isn't 5.14 we are supporting now. -list of operating systems: https://continuity.datto.com/help/Content/kb/siris-alto-nas/360040893811.html

Hi , thanks for your comment

[mihaime]

@Swistusmen are CentOS / RHEL on your radar for adding support in the nearby future?

[Swistusmen]

@iv-dev we have a pull request with fix for that, it needs to go through quality process, but pls expect fix soon @mihaime yes they are, here we also have big improvements currently under testing both of this PR when merge should give support for RHEL 9, Centos 9

[Swistusmen]

@iv-dev should work now

[iv-dev]

@Swistusmen Unfortunately, the build problem is still there

Sorry for late response, was on holiday. Can you please provide the way how you are installing dattobd? I see in your logs: grep: /lib/modules/5.14.0-373.el9.x86_64/System.map: Permission denied performing sys_umount lookup grep: /lib/modules/5.14.0-373.el9.x86_64/System.map: Permission denied performing sys_oldumount lookup grep: /lib/modules/5.14.0-373.el9.x86_64/System.map: Permission denied performing sys_call_table lookup grep: /lib/modules/5.14.0-373.el9.x86_64/System.map: Permission denied performing printk lookup grep: /lib/modules/5.14.0-373.el9.x86_64/System.map: Permission denied

and this worries me a lot.

Hello, I did not install dattobd, but built it from the source code according to the instructions given here. https://github.com/datto/dattobd/blob/main/INSTALL.md

And yes, sorry for the oversight, I didn't run the make with sudo privileges. I restarted the project build with sudo privileges. The build errors are the same. The report is attached build_log.txt

@iv-dev I am working on that issue just now, for sure problem reproduces and I am thankful for raising that.

@iv-dev I am working on that issue just now, for sure problem reproduces and I am thankful for raising that. According to your latest message:

1. it's strange for me that you have in build_log:
   make[3]: Entering directory '/usr/src/kernels/5.14.0-373.el9.x86_64'
   make[3]: Leaving directory '/usr/src/kernels/5.14.0-373.el9.x86_64'
   Because it should be
   KDIR := /lib/modules/$(KERNELVERSION)/build from Makefile in src/.
   Have you changed something here or it just happened? Does your code include any changes?
   [for  /lib/modules/$(KERNELVERSION)/build it still doesn't work, but issue is another]

2. Can you share commends you have used to install packages needed for building process?

3. Which commit are you building?

Hi .I download and used the zip file of the main branch. I did not make any changes in the code

Hi @iv-dev , unfortunately my current workload cannot let me fully focus on this ticket, although I've managed to do some work which results you should see here: https://github.com/Swistusmen/dattobd/tree/building-on-new-kernels I know it build on kernel pointed by you although I haven't done more than sudo make, so I wouldn't consider it as tested. At this level I need to jump to something else and will return to this within a month.

Hi. No problem, I understand the difficulty of the task and your workload:). Of course I'll wait. I can test my tasks on Ubuntu, no problem, but Сentos is more actual for my customers. Thank you.

[Swistusmen]

Of course I understand your needs and hope could dedicate to this task. Generally supporting Centos9 is hard cause it's releasing kernel non-stop- 5.14.0 is stable, but what goes further changes (you have made a ticket for 368, now you are building on 373, I have tested on 404 and it's not the newest).

[Swistusmen]

@mihaime I wanted to inform you that we officially released support for RHEL 9.3, so our latest tag works on it.

[mihaime]

Thank you @Swistusmen. I'll test this out.
