I have a gmirror partitioned into 3 gjournalled filesystems.
The gmirror and gjournal modules have been loaded; the mirror and
journals are reported in dmesg; the geoms appear in /dev and in the
"gjournal status" summary; and "gjournal dump" finds the metadata.
However, when I ask for individual status reports, gjournal claims
that the geoms don't exist. What's going on? (This log shows gm0a
as an example; the others behave the same way.)
In case it matters, the partitions are not mounted.
