zfs.ko init hangs with fedora 2.6.33.6-147.fc13 kernel,about openzfs/zfs

behlendorf commented on July 18, 2024

It seems to work fine for me on my FC13 box (2.6.33.6-147.fc13.x86_64). Can you try a clean checkout and NOT running autogen.sh. There is no reason to be regenerating configure particularly using a newer version of autotools I haven't tested extensively with.

I have tried, - uninstalled rpms, did fresh git clone, ./configure and rpm build and installed new rpm. strace modprobe zfs ended with similar result:

and after that computer does not reply pings.
I think it is related to the status of disks there. I did benchmarking, installed zfs-fuse 0.6.9 on the same machine and leaved zpools there in "online" state before switching back to spl/zfs. I will try to check this by zeroing out partition with zpool, and then will check if the problem can be recreated.

It would be helpful if you could get the console logs, the strace output only shows the module being loaded.

Here it is: console log for 'modprobe zfs' on the computer with problem.

Thank you that's exactly what I needed. It clearly shows a stack overflow which explains your symptoms and the full stack trace so we can reduce the usage.

behlendorf commented on July 18, 2024

Ned Bass worked on numerous stack reduction in the latest source. In particular we believe commit 410d8c4 should be enough to address this issue.

I can confirm 'modprobe zfs' now does not hang the system. I've preserved partition with zpool and the kernel. Now it loads the module, but unfortunately it can not deal with zpool.

OK, we're getting somewhere. The original bug is fixed, the next issue you observed is actually a duplicate of issue #39.

from zfs.

seriv commented on July 18, 2024

Issue #39, null dereferencing, is fixed, but some problems with these old bad zpools remain.
Although zpools are imported, they are partially working. There are the calltrace in /var/log/messages:

After import I can see zvols and zfs objects but not zpools:

[root@localhost ~]# zpool list

-         -      -      -      -      -       -  -

rpool/backup   41.3G  44.3G    16K  -

I can access zvols, successfully mounted /dev/zvol/data/phoronix, with /var/log/messages:

from zfs.

behlendorf commented on July 18, 2024

OK, the call trace in /var/log/message is purely debug. It's just a backtrace for a particularly large kmem_alloc which needs to be fixed. I'll take care of that shortly.

The zpool behavior is strange I haven't seen anything like that before. Getting the strace output from both the 'zpool list' and 'zfs snapshot' commands would be helpful to debug this.
