How to fix ZFS corruption?

[rum-z]

I recently switched to ZFS for my cache because I thought it would be more reliable than BTTRFS. I'm about a month into it and experienced my first corurption already. I'm seeing: PANIC at range_tree.c:436:range_tree_remove_impl()

I am new to zfs. Are there any good recovery methods for ZFS? 

For extra contedt: I've been using 6.12.6 since it came out

You can try mounting the pool read-only:

 

zpool import -o readonly=on cache

 

if it works, start the array, it will still show up as unmountable but the data should be under /mnt/cache.

 

P.S. having corruption issues with multiple filesystems suggests there can be an underlying hardware issue, like bad RAM

Thank you. Sadly that did not work, I ended up wiping the drives, and starting fresh, back to bttrfs for the cache drive. Thankfully I had backups. I'll look into the bad RAM. I wonder if bad RAM broke the zfs since it uses RAM.
