If one is willing to accept that data is lost (like the log device is totally
smoked), is there a way to boot knowing that you may have some data loss, or is
the only option to boot alternate media and force a pool import (assuming that
works without the log device)?
I think it's the latter. I am not aware of any way to select a behavior similar
to import -m or import -F during boot.
Perhaps... ZFS_IMPORT_MISSING_LOG should be a default behavior for a root pool
or maybe the behavior could be controllable by a tunable.
Maurizio,
you might want to try the following patch as an interim solution for your
environment:
--- a/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa.c
+++ b/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa.c
@@ -4112,6 +4112,7 @@ spa_import_rootpool(const char *name)
}
spa->spa_is_root = B_TRUE;
spa->spa_import_flags = ZFS_IMPORT_VERBATIM;
+ spa->spa_import_flags |= ZFS_IMPORT_MISSING_LOG; /* XXX make tunable */
/*
* Build up a vdev tree based on the boot device's label config.
HI all,
unfortunately the patch don't works. The laptop returns the same error
message: "Mounting from zfs:tank0 failed with error 6" and the same
"mountroot>" prompt.
I am available for further testing if needs.
Thanks anyway,
Maurizio
