Crash when trying to mount ZFS filesystem

[ghost]

Hi everyone,

So I have a homemade NAS running debian 12. The OS is on separate SSD (under ZFS) and I have 6 disks for data which I configured as raidz2.
I set up 4 different storages, everything has been working really fine since several years now until last week.

I was massively deleting data and the system crash suddenly; since then I am not enable to mount one the dataset anymore...
I had to set allow_mount=noauto to be able to boot correctly. I tried tons of things like mount -f, zfs scrub (which says that the pool is actually sane). The problem is specific with this dataset because the 3 others mount perfectly and are usable.

I don't have any access to any log at all and... I'm lost to be honest :(
Some usefull infirmation: dedup and compression are enabled and that dataset.

The best thing I can provide is that picture of a stacktrace (I guess it is): https://imgur.com/ukuwQ90

Do you have an idea of what's happening and how I can solve this problem?

Regards;

Solved it: It was actually a hardware problem.... It was to determine as the system boot normally and after a while. I suspect it was somehow in the RAM bus (not the RAM itself).
