Make sure the the geom_stripe module is actually loaded. (with kldstat)
If it's not already loaded, do a kldload geom_stripe (which creates =20
the /dev/stripe directory, if the metadata exist on the disk =20
("automatic mode") and perform a normal fsck afterwards. (e.g fsck -y /=20=
dev/stripe/st0a)
If the metadata /(manual mode) are not stored on the disk, you need to =20=
issue exactly the same commands to recreate it as you originally did.
All this is nicely documented in the man page (man gstripe)
By adding the following line
geom_stripe_load=3D"YES"
to /boot/loader.conf you make sure the stripe will be available after =20=
reboot (at least in "automatic mode").
Hope this helps
Regards
