Hey.
Recently my server started behaving strangely, hanging randomly.
It has been rock solid for years, but now i can't even start the main array without kernal panic, the UI dies and i loos connection. starting the array in Maintenance Mode works fine.
Error when starting the array:
VERIFY3(size <= rt-yrt_space) failed (281442900004864 <= 1786707968)
PANIC at range_tree.c: 436 :range_tree_remove_impl()
Ran memtest86 twice with 4 passes each, both passed, no errors.
I have a few zpools, perhaps a problem with one of them. but i managed to import them all without any fuss.
Not sure what else to try. Dockers and VM are disabled.
Any ideas very much appreciated, diagnostics and screenshots attached.
thanks.
