I try to remove the FAULTED cache device sdb (zpool remove tank sdb), but it doesn't work and shows: cannot remove sdb: operation not supported on this type of pool

I found that this pool contains a device with the same path name sdb in raidz2-0 group. The zpool command seems to match the device in raidz2-0 group.

In this case, how can I remove the cache device sdb in this pool?

zpool status -g and then remove the ID it reports for the faulted device, I believe.

It works, thanks.
