Hi @seth-arnold, adding some details to this bug:
dn->dn_type = 19 = DMU_OT_PLAIN_FILE_CONTENTS dn->dn_type = 20 = DMU_OT_DIRECTORY_CONTENTS So they look correct, they seem to be just plain files and directories. However, the specific object that is causing the panic seems to have dn_type=32 that is DMU_OT_DSL_PERMS (that's a bit odd, I don't see any other object types like this in your dmesg), moreover the output of "zdb -dddd" shows a lot of UNKNONW stuff (checksum and compression type for example, they are UNKNOWN). So, it seems that we may have some corrupted data here. Do you see any error if you try to run a simple `zpool status -v`? Do you know exactly which pool / volume / filesystem is causing this problem? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1861235 Title: zfs recv PANIC at range_tree.c:304:range_tree_find_impl() Status in Linux: New Status in zfs-linux package in Ubuntu: Incomplete Status in zfs-linux source package in Bionic: New Bug description: Same as bug 1861228 but with a newer kernel installed.
