Thanks for the work on this, guys!
I've already managed to find something odd. This message only appears
on console, not via pty/tty.
icarus# zpool create backups ada2
Solaris(cont): !created version 28 pool backups using 28
src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa_history.c
contains:
490 void
491 spa_history_log_version(spa_t *spa, history_internal_events_t event)
492 {
493 #ifdef _KERNEL
494 uint64_t current_vers = spa_version(spa);
495
496 if (current_vers >= SPA_VERSION_ZPOOL_HISTORY) {
497 spa_history_log_internal(event, spa, NULL,
498 "pool spa %llu; zfs spa %llu; zpl %d; uts %s %s %s %s",
499 (u_longlong_t)current_vers, SPA_VERSION, ZPL_VERSION,
500 utsname.nodename, utsname.release, utsname.version,
501 utsname.machine);
502 }
503 cmn_err(CE_CONT, "!%s version %llu pool %s using %llu",
504 event == LOG_POOL_IMPORT ? "imported" :
505 event == LOG_POOL_CREATE ? "created" : "accessed",
506 (u_longlong_t)current_vers, spa_name(spa), SPA_VERSION);
507 #endif
508 }
A "zpool destroy", etc. does not print any similar message. It only
happens on pool creation. Is this intentional behaviour? What does
"Solaris(cont)" represent in the context of FreeBSD?
