I have a 894GB gstripe that I've put gjournal on top of. Since it was
an unused stripe I placed the data+journal into the same partition.
The server is fairly heavily used and hung suddenly. On reboot I got
this in the dmesg:
GEOM_JOURNAL: Journal 3472355975: mirror/gm0s1e contains journal.
GEOM_STRIPE: Device st0 created (id=2649322337).
GEOM_STRIPE: Disk mirror/gm0s1f attached to st0.
GEOM_MIRROR: Device mirror/gm1 launched (1/1).
GEOM_STRIPE: Disk mirror/gm1s1f attached to st0.
GEOM_STRIPE: Device st0 activated.
GEOM_JOURNAL: Journal 2630378703: stripe/st0 contains data.
GEOM_JOURNAL: Journal 2630378703: stripe/st0 contains journal.
GEOM_JOURNAL: Journal stripe/st0 clean.
GEOM_JOURNAL: Timeout. Journal gjournal 3472355975 cannot be completed.
That last line worries me.
>From a quick google, it appears that the gjournal is too small. Since
I created it with the single partition, I would have expected the journal
to be autosized correctly.
I know the OS is a little out of date but has been working very well until
the past couple months. I have 1 hang approximately every month.
