OS hangs when running snapshot command on RHEL8.4 #252

Closed yito24 closed 2 years ago

yito24 commented 3 years ago

I installed and tested the driver on RHEL 8.4 or Alma Linux8.4. I tried Ver 0.10.15 and 0.10.16 . Issue occurs in both cases.

Execute the snapshot of [ / ] with the command below causes the OS to hang.

dbdctl setup-snapshot /dev/sda4 /.datto 0

It does not occur in RHEL 8.3. Occurs only on kernel 4.18.0-305.

This issue is fixed with the code below. https://github.com/elastio/elastio-snap

In addition, most of the problems such as kernel 5.x problems and Debian and Ubuntu installation problems have been fixed.

I'm not sure why @e-kov hasn't sent their fixes to us upstream, they would certainly be very welcome. It's on my radar to look into this...

yito24 commented 3 years ago

As far as I test, the following issues have been fixed and are working properly.

RHEL8.4 Hang problem (#252) Debian9 Read only problem (#251) Debian11 kernel5.10 Hang problem Debian10/Ubuntu20.04 kernel5.6 or later install problem (#221 #234 #239 #256) Suse 15.3 Install problem (#253)

I hope you will fix those issue.

I tried to dig through the various topics on the support problems for >5.4, but still I am not sure what the current status is.

Was the code from https://github.com/elastio/elastio-snap already merged/included and if yes: is it solving the various problems?

yito24 commented 2 years ago

The source code has not been updated at all. Therefore, dattobd does not solve this problem.

aradhir commented 2 years ago

Is anyone working on that?
