Crashing under Gentoo 6.10.6 #16502
Comments
@mauricev can you please update this with the information requested in the issue template. We need that info to begin triage. |
Distribution Name | Gentoo |
Are you doing something in particular at the time this happens? I see docker and overlay filesystems are in play; does this coincide with a particular docker activity? You say "occasional", so it would be nice to line this up with a particular action. Did anything change on this system recently? You mention another system on 6.10.5, and a recent upgrade. Was this system running that older kernel before? Did this happen then? If you're able to downgrade your kernel, I'd be interested to see if anything changes there. Are you able to try with a release OpenZFS (say 2.2.5)? |
This is a new installation replacing an older system. This new system has a new, third docker container and when I build the image for it, about 50% of the time, this crash will happen. However, it just happened again today unrelated to my building a docker image. There is another nearly identical server running 6.10.5, but without docker. It has not crashed so far. Could a low-memory condition trigger zfs to crash this way? I think I would have to revert the kernel version to install zfs 2.2.5. |
Can you please share the build command/Dockerfile? 50% luck is good enough, I'll give it a try (need to make sure 6.10 runs well, we'd like to move onto it at vpsFree) |

I had no luck, left that running in a loop over night, no crash :( Can you describe how the pool and datasets are set up? What properties are set, etc.? |
I had run the docker build twice and it did crash again once. When I run the command on the staging server, it never crashes but that has only btrfs disks. |
Maybe it's something in |
start.sh
requirements.txt
Come to think of it, the crash always occurs during the processing of requirements. |
I left it looping for 8 hours, nothing :( |
Uh I enabled block cloning in hope to reproduce this, perhaps it could be related... - only to see endless txg syncs with no data written whatsoever. OK, got it, continuing to keep that feature off and recreating my dev pool now :-D |
I have the most recent zfs-9999 installation (I assume this is a recent github snapshot) of ZFS installed on Gentoo x64 with gentoo-sources kernel 6.10.6. I have one mirrored zpool. I am seeing occasional kernel panics.
The pool passes scrub with no errors.
I'm not sure of any other way to document panics. I have another similar system slightly older running 6.10.5 and it has yet to crash.
