That post refers to bug 6740597 http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6740597 which also refers to http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=2178540 So it seems like it's fixed in snv114 and s10u8, which won't help your s10u4 unless you update.. /Tomas -- Tomas Ögren, st...@acc.umu.se, http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Umeå `- Sysadmin at {cs,acc}.umu.se _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
