Thank you for your help. As per your suggestion I have replaced the NVME drives and rebuilt the cache pool and am now restoring from backup.

Same problem root@NAS0:~# /usr/sbin/zpool import -o readonly -d /dev/nvme0n1p1 cache Message from syslogd@NAS0 at Oct 12 20:55:22 ... kernel:VERIFY3(size <= rt->rt_space) failed (281442900570112 <= 2168373248) Message from syslogd@NAS0 at Oct 12 20:55:22 ... kernel:PANIC at range_tree.c:436:range_tree_remove_impl()

Hi, I have been running Unraid for a couple of years without problems, but recently I get kernel panics trying to mount the cache pool. This results usualy in two frozen cores root@NAS0:/boot# /usr/sbin/zpool import -N -o autoexpand=on -d /dev/nvme0n1p1 -d /dev/nvme1n1p1 6597617673992789075 cache Message from syslogd@NAS0 at Oct 12 16:19:49 ... kernel:VERIFY3(size <= rt->rt_space) failed (281442900570112 <= 2168373248) Message from syslogd@NAS0 at Oct 12 16:19:49 ... kernel:PANIC at range_tree.c:436:range_tree_remove_impl() How can I solve this problem?
